You can have the finest SaberJet XP equipment and the sharpest blade for the material and still end up with a less than quality cut. High quality cuts require the right saw arbors, the proper coolant or lubricant for the material, and just the right combinations of feed and speed.

How Slitting Cuts Differ

If you visit any of the internet forums frequented by pro and hobby CNC’ers  you will see hundreds and hundreds of threads about slitting saw cut problems. Grown men figuratively cry over broken blades, broken arbors, and ruined work. Seems like if it can go wrong when you are machining, it will probably go wrong when you make a cut with a slitting saw. But some times, you just gotta have a slitting saw cut.

Pros. Slitting saws are perfect for a very narrow cut. You don’t want to use them for thick or deep cuts. But even if you must go deep it’s still easier than using an end mill.

Cons. Slitting saws need slow cutting speeds. Especially for large blades. Feed speeds need to be slow, too. But don’t let the blade dwaddle in one place or run super slow. Slitting cuts need lots of cutting oil or lubricant. If the slit is really thin, it’s hard to get the fluid into the scene of the cutting action. Same for deep slits.

Don’t Skimp on the Fluid

It doesn’t matter the material or the blade type, slitting cuts demand plenty of lubricant. Slitting saw blade are thin and fragile.

The blade metal is heat treated. That keeps it hard and sharp. As the blade cuts, friction is created. Friction equals heat. Heat ruins blade treatments.  So, the blade dulls quickly. In addition, swarf can fuse to the blade. Swarf fusion ruins work and kills blade. All bad things.

Stop swarf fusion with plenty of cutting oil, lubricant, or even air. Provide a constant flow of liquid or air to the slitting blade. The blade stays cool and the chips stay clear. All good things.

Don’t Skimp on the Saw Arbors

So you have a most excellent piece of equipment, a fabulous saw blade, and a flood of fluid, coolant or air. It’s the perfect set up. Don’t mess it up with a crap saw arbor.

There are plenty of cheap, imported saw arbors on the market but you need to steer clear of them. You get what you pay for when it comes to CNC’ing. If you don’t pay much, you won’t get much. Chinese-made  arbors are rarely every true. That’s a problem when making horizontal slits and slots.

In one of those famous internet forums, a fellow CNC’er complained that his saw was wandering like a drunk sheepherder. The group told him to get a grip and get a saw arbor made by  Sierra American! Except they forgot to tell him where to find Sierra American products. And that’s at The Tool Company.

Gone are the days when you first started machining. Was your first machine an end mill? Did fly cutters terrify you?  As a seasoned machinist, do you get the most out of your tools? Stretch your mind and skills. Think out of the box. Here’s new slitting saw and slitting saw arbor uses. Maybe one will spark your imagination.

saw arbors hold saw bladesSlice it Off

No, don’t use your slitting saw arbor and blade to remove a finger or other body part. But that doesn’t mean you can’t cut a part off and finish it by hand. The result won’t be the same as with a fly cutter, but it is an alternative. On a 3 axis mill, just cut the piece off with a slitting saw. Once removed, finish the underside by hand. This is the perfect solution for machining a very thin part or working on a piece that is particularly hard to hold. Just cut it off and finish it by hand. Hand finishing the piece saves time. If you ruin the work with a machine finish, you’ve got to start over. It wastes time, money, and material.

Cut a Relief Slot

Does your part need a little relief? Don’t let it break. Cut a relief slot and prevent a break.

Relief slots provide just enough give without destroying the integrity of the part.

A relief slot would help here


Cut your relief slot with a slitting saw. Hold the blade firmly in place with a slitting saw arbor and make the slot in just one or two passes. A slitting saw arbor with a deep cap and low profile will get you as close as you need to be.

Selecting a Slitting Saw and Slitting Saw Arbor

Because slitting saws are thin and run fast, they get hot fast too. Select a carbide blade  if the budget allows. While steel is less expensive, carbide lasts longer.

No matter the blade material, use copious amounts of fluid. Did you know that slitting saws run hot? Of course you do, we just told you! A flood of coolant lets you cut long and cut fast.

Picking the slitting saw arbor is easy. Just buy one at The Tool Company. Their deep, low profile caps  get your blade close. The “Vibra Core” design absorbs vibration. Anytime you reduce vibration you reduce runout.

The slitting saw arbor made in America for American machinists. Just like everything at The Tool Company. Buy yours today and start looking at the slitting saw differently. It’s one of the most versatile and underused tools in your box.



You can start with the best equipment and the finest blade. But, if you don’t use a high quality saw arbor, the right fluid and the proper feeds and speeds you won’t end up with a quality cut. Quality cuts come from quality saw arbors.

saw arbors hold saw bladesHow Slitting Saw Cuts Differ

The internet is packed with forums for machinists. One of the most common denizens of these forums are those with slitting saw cuts. They complain about broken blades, broken arbors, and tons of destroyed work pieces. If it can go wrong in cutting, it will probably go wrong with a slitting saw cut. But  some times you just need that slender cut from a slitting saw.

Pros. Slitting saws excel when you need a very slender cut. No, they aren’t designed for thick cuts or particularly deep cuts.  But that doesn’t mean you can’t cut fairly deep. It’s harder to get a thin slot with an end mill than a slitting saw.

Cons. Don’t hurry. Slow speeds are the norm for most slitting saws. This is especially true when the blade is large. Feed speeds are also slow. But that doesn’t mean you can let the blade dwell. Slitting saws demand copious amounts of cutting oil or lubricant. Sometimes it is hard to get fluid to the cutting site if the slit is particularly thin or deep.

Be Generous with Fluid

No matter the material or blade, use generous amounts of lubricant. Slitting saw blades are very thin. They are also incredibly fragile. That’s why they break so easy and confound those forum denizens.

The saw blade has been heat treated to keep it hard and sharp. As the blade cuts, it generates friction. Friction creates heat; and heat destroys the blade treatment and dulls the blade quickly. Chips and/or  work material  fuse to the blade. Now you’ve ruined the work and murdered the blade.

Plenty of cutting oil or lubricant provides a constant cooling. It keeps the blade clear of chips. It is good to be generous with your fluid.

If you have an awesome machine, a spectacular blade, and a truckload of coolant, don’t ruin things with a crap saw arbor.

Many cheap, imported arbors flood the market. With tools, you always get what you pay for. Don’t pay much, don’t get much. Those imported arbors are warped. That’s a real problem for true horizontal cuts.

One internet forum denizen complains his saw was wandering like a drunk sheepherder. The group told him to get with it and get a good arbor. That would be like  a saw arbor from The Tool Company!

Did you start machining with an end mill? Did fly cutters terrify you? It’s okay, that’s where most machinists start. But if you’ve been working for awhile, those days are long gone. That doesn’t mean you get the most out of your tools. Take a minute to look at some jobs differently.  Grab your slitting saw arbor, load your blade, and open your eyes.

Use Your Hands

There’s nothing wrong with a hand job. No, not that hand job. We’re talking about cutting a part off and then finishing it by hand. The hand finish quality isn’t equal to a fly cutter, but it is an alternative. On  a 3 axis mill, just use your slitting saw and lop the piece off. Now you can finish the underside by hand. This is the perfect answer if you are machining a very thin part or working on a piece that is particularly hard to hold. Just cut it off and give it a hand finish. Believe it or not, you’ll save time by hand finishing the piece. That’s because if you ruin the part trying to machine finish it you’ve got to begin again. That wastes time, money, and material. Don’t waste.

Use Slots for Relief

We all need a little relief from time to time. That includes your parts. No, your parts don’t need to take a break, they need a relief slot to stop breakage.

A relief slot provides a part just enough give to clamp tightly without destroying part integrity.

The slitting saw is the superior tool for cutting a relief slot. With the saw blade tightly held in place with a good slitting saw arbor, make a relief slot in one or two passes. A good slitting saw arbor has a deep cap and low profile to get the blade as close as you want it to be.

slitting saw arbor setPick a Good Slitting Saw and Slitting Saw Arbor

Because slitting saws are thin and run fast, they heat up very fast. Buy a blade made from carbide if your budget can handle it. Steel costs less, but it doesn’t have the staying power of carbide.

Regardless of the blade metal, always run with copious coolant. Remember, slitting saw blades run hot. Fluid will let you make long cuts and fast cuts without warping.

Selecting a slitting saw arbor is simple. Just buy your slitting saw arbor from The Tool Company. Their deep, low profile caps get the cutter close. A”Vibra Core” design absorbs vibration. Less vibration means less runout.

Made in American for American machinists. Buy a slitting saw arbor today. And start looking that your slitting saw blade a bit different. Make it one of the most valuable tools in your cutter arsenal.


Ready to grow? You should be. Grab your slitting and slotting saw and your slitting saw arbor and get working. The American manufacturing outlook is bright this year so you better grab sunglasses with your safety glasses.

growth in GDP is good news for manufacturing

GDP is Growing

Growth in GDP

The overall gross domestic product was initially expected to increase 2.5% in 2018.  But with 6 months of growth under our collective belt, turns out GDP should grow 2.9% this year. That makes 3 years of consecutive growth. That’s even better than 2016.  It could be higher, if the stock market is any indication. We are just days away from a record for number of days a bull market.

What this means for Manufacturing

Here is better news. Manufacturing should rise almost as much as GDP. This is the time to get your tools (know where you put your slitting saw blade and slitting saw arbor) and get to work. U.S. manufacturing is forecast to  grow 2.8% this year. The Bureau of Labor Statistics is projecting job growth too. 20.5 million new jobs before 2020. Consumer spending and business investment are up too. That’s good news for manufacturing, too. There will be more health care spending. More spending in health care requires more medical supplies. In the US, mills and lathes are busy. Grab your accufeed to drill those small holes and your slitting saw blade and slitting saw arbor to make tiny cuts. Healthcare isn’t the only industry that needs you!

There will be an additional 2.1 million jobs in technology. If you can design and convert to G-code you are in high demand.

Growth in Defense and Aerospace Industries

You don’t need alien technology or work experience at Area 51 to get in on aerospace. Globally, aerospace and defense are expected to grow 4.1%. After their recent decline, this growth is welcome. There’s a backlog of civilian plane orders to clear. That’s going to require parts. Who is going to machine the parts? Let’s machine them in the U.S. The United States makes up half of aerospace global production. That’s a lot of work for machinists and machine shops. Are you ready?

Grow through Quality

It’s no secret, some of the most successful machine shops grow because they have a reputation for quality. If you’re going to machine for aerospace, defense, medical or other high-tech industries, you need precision and a commitment to perfection.

By the beginning of the year, most people are tired of celebrating. Not The Tool Company. We’re not done celebrating by far. We’re celebrating the slitting saw arbor today. And we’re celebrating other saw arbors too. If Arbor Day can celebrate trees, January 10 can celebrate the Slitting Saw Arbor. The average person thinks arbors are leafy areas. But to a machinist, an arbor is the bar or shaft holding a spinning cutting tool. So, let’s celebrate the slitting saw arbor and make today Saw Arbor Day.

slitting saw arbor setThe Slitting Saw Arbor

The slitting saw and the slotting make narrow cuts. These saws need an arbor that keeps the blade steady. This is even more important if you are run at high speeds. Slitting and slotting saws work best if you don’t make those deep slits or slots in one pass.  Get the best results using the same peck cycle used for drilling. Yes, a good slitting saw arbor holds your blade on the vertical or horizontal, but it can’t protect the blade from heating up and fouling if you run too fast.

Slitting saw arbors must be different. Because many slitting saw cuts are deep, the slitting saw arbor has an extra long reach. They must be the NBA players of the machine shop.

Slitting saws get up close to their work. So, slitting saw arbors must get the cutter as close as possible.

The slitting saw arbor is a hard working tool. That’s why we say “Hoo Rah” for the slitting saw arbor.

The Ultra Precision Arbor

set of saw arborsThe slitting saw arbor may work slow, but the ultra precision arbor is all about speed. High speed cobalt and carbide saws require a steady arbor. They provide extra support and prevent cutter slippage. Their weldon shank and hub configuration provides the rigidity necessary for small tools. They excel at high speed CNC applications.

The ultra precision arbor works hard at engraving, micromachining, or grinding. They don’t complain; the just do their job.  Hoo Rah for the ultra precision arbor.

General Purpose Arbors

 saw arborThe slitting saw arbor and the ultra precision arbor are specialists. But, the general purpose arbor is the polar opposite. It is the unsung hero of arbors. It holds all of the other saw blades. The general purpose arbor absorbs vibrations, gets the cutter close to the work piece and does it all with rigidity. This hard-working arbor doesn’t chatter. It is testament to the virtue of hard work. Day in and day out it keeps the blade from straying.  Yipee for the general reach arbor.

Every Day is Arbor Day at The Tool Company

The Tool Company  sells the highest quality saw arbors made. Every day is Arbor Day at The Tool Company. Every slitting saw arbor has a deep profile cap. You get up close and personal with the cutter. The cutter gets close to the work. That’s something to celebrate.

Every tool we sell is made in the USA.  A full 5 year warranty is standard on every product. Celebrate Saw Arbor Day with the best. Order your slitting saw arbor, ultra precision saw arbor, or general purpose arbor today.

You can have the most expensive equipment and the highest quality blade, but if you don’t have a high-quality saw arbor and apply the proper fluid as you cut with the correct feed and speed rates then you aren’t going to end up with a clean cut.

Cutting with a Slitting Saw is Different

saw close upThe internet is loaded with CNC’ers posting, complaining, and asking about problems with slitting saw cuts. If it can possibly go wrong with machining, it will probably go wrong when you try to make a cut with a slitting saw. Broken blades, broken arbors, ruined work are all woes associated with slitting saw cuts gone wrong.

Slitting Saw Advantages. Let’s face it, if you need a very thin cut, a slitting saw is the tool for the job.  They really aren’t designed for thick  cuts, you can make a  thin cut  fairly deep. It’s also much easier to get a thin cut with a slitting saw than trying to do it with an end mill.

Slitting Saw Disadvantages. Most slitting saw cuts require slow speeds.  This is particularly true if the blade is large. So while the feed speed needs to be slow, you run the risk of letting the blade dwell if you run too slow. Slitting saws requir lots of cutting oil or lubricant. It can also be very hard to get the cutting fluid to the slit, especially if the slit is particularly thin or deep.

Let the River Flow

It doesn’t matter the material you are working or the blade you are using, making a slitting cut requires a flood of lubricant. This is because slitting saws are very thin by nature.  As far as saw blades are concerned, they are fragile as well.

Your slitting saw blade has been heat treated to make it hard and keep it sharp. As the blade makes contact with the material and begins to cut, friction is created. Everyone knows that friction creates heat.  This heat will ruin the slitting saw blade treatment and as a result the blade will dull quickly. Heat can also cause chips and/or the work material to fuse to the blade. That’s a recipe for ruined work and ruined blades.

By flooding the work with plenty of cutting oil or lubricant you keep the work area cool and flush away chips.

A Superior Saw Arbor is Necessary if you Want Superior Cuts

So you have a great machine, a killer blade, and loads of coolant. Don’t ruin your perfect set-up with an under performing saw arbor.

There are plenty of cheap, imported arbors for sale. But like most things in life, you get what you pay for. That means if you don’t pay very much, you probably won’t get very much. Foreign arbors are rarely very true. If you need to make a horizontal cut, this causes very true problems.  You aren’t going to get a quality cut if the saw arbor allows the blade to wander like a drunken sailor.
