Every ultra precision saw arbor sold at The Tool Company holds your blade for precision cutting use after use. It doesn’t matter if your CNC application calls for a high speed steel blade or a carbide saw, you need saw arbors as precise as your saw.

saw arbors hold saw bladesThe Cobalt Enhanced High Speed Steel Option

Cobalt enhanced high speed steel is the alloy of choice for CNC saws and has been for ages. Alloys are mixtures of metal and the most common HSS mixture includes a generous helping of tungsten and with cobalt added for strength and resistance to wear. Cobalt-enhanced HSS makes working with titanium alloys, stainless steel, and other metals easier.

Because HSS is strong, it is perfect for  face mills, slitting saws, and gear cutting.

HSS costs less than carbide and is easier to sharpen to boot.

HSS does have a downside. That is the limitation on speed. HSS can’t run as fast as carbide steel. But, if tool life trumps speed (like in ultra precision cutting) HSS comes out on top.

The Carbide Option for Precision Cutting

In high speed CNC applications, carbide has replaced high speed steel. Carbide may not be as strong as HSS, but it cuts with a greater speed range.

A carbide saw can cut 4 to 12 times faster than HSS. That’s why carbide is well-suited for high speed CNC applications.

If carbide is out of the budget or you need the durability of HSS, then check out how to get more performance from your HSS tools.

Why Use Our Ultra Precision Saw Arbors

precision saw arborsNo matter the saw blade material, if you are using an ultra precision saw, you need an ultra precision saw arbor. This is true no matter the application. From  cutting, grinding, or sharpening tools, if you need  precision, you can’t settle for an arbor that chatters or slips. Precision requires control. Control requires an ultra precision saw arbor from The Tool Company.

With a variety of sizes, The Tool Company has the diameter you need in the ultra precision saw arbor you will love. The unique “Vibra-Core Design”, results in a saw arbor that actually absorbs cutter vibration. So you can run at normal depths, feeds, and speeds and maintain productivity without chatter, slipping, or vibration.

You also get the closest cutter to work area on the market when you buy your precision arbor at The Tool Company.  Our saw arbors are all made in the USA, feature Weldon shanks, and are covered by a full 5 year warranty.


Do you machine with precision or do you machine with ultra precision? Know the difference?  Ultra precision machining removes material to an ultra-high standard at a tolerance of tolerance of 0.002″ or 0.005 MM. You can grind, turn, and mill at ultra high precision tolerances.  But, to maintain those tight tolerances you can’t tolerate staggering tools. Ultra precision machining demands ultra rigidity. You need an ultra precision arbor to get that required ultimate rigidity.

Ultra Precision Machining for Different Industries

Manual and CNC machinists serve many different industries. Parts for defense, dental/medical, aerospace, and high tech industries require machining with ultra precision and tight tolerances. It’s not easy to produce these very small parts. Think of them as tiny in size and huge in requirements. But, the pay-off is tremendous. This is definitely a money-making niche.

Are you up to the challenge? If so, customers are waiting. See, there’s no room for mistakes when you have tight specifications. But if you can handle tight tolerances and produce parts on schedule you’ve got a ready-made market. Just prove your shop is up to the job.  Assure them you have the machines, training, and tools to get it done. That means using ultra precision tools held with with an ultra precision arbor.

ultra precision saw arborUse an Ultra Precision Arbor for Tight Tolerances

Precision machining means removing material precisely. That takes a cutter held by an ultra precision arbor for maximum rigidity. Rigidity is required if you want to keep the cutter on the work instead of staggering around the stock. It doesn’t matter if you are protoGold Series ultra precision arbor settyping or producing the finished product, the finished piece must match the job specifications. You must control the cutter at all times. Keep the cutter on the job with an arbor. Keep cutting with ultra precision with an ultra precision arbor from The Tool Company.

The Tool Company sells tools made in the USA with ultra precision. You need rigidity, we’ve got it. If you want tight tolerances, don’t tolerate anything less than The Tool Company quality. Order today.

The Tool Company is just full of good news. Your favorite seller of the ultra precision arbor and fly cutter is stoked to share some good news for metalworkers. The Gardner Business Index for Metalworking has been decreasing in durable goods capacity utilization.

So What?

Why do you care? Because its incredible news for metalworkers. So, you better grab your tool tray, your collet wrench and your ultra precision arbor and get to work.

Because the backlog index is accelerating, durable goods capacity utilization should shift from contraction to expansion. After 22 months of contraction, that’s good news too.

Remember,  the backlog index is a growth leading indicator.  And, it’s a reliable leading indicator to boot. Finally, contraction is ready to shift to growth.

It’s time to work.

Potential for Growth in Jobs

The U.S. Bureau of Labor Statistics predicts a faster than average job growth rate. They predict growth of 17% to 2024. This includes jobs for metal and plastic workers. For toolmakers, the news is even better. How does a job growth rate of about 6% sound to you? Toolmakers are getting close to retirement and few workers are entering the field. This is one job with tremendous potential for growth.

Millwrights have an even brighter future. Their predicted job growth rate  is 14%.

So, CNC workers have lots of good news to cheer about. When the manufacture of durable goods grows the number of jobs grows too.  It doesn’t matter if you make goods or make parts, you’re going to have plenty to do. So, get your tools ready!

Ever get the feeling your shop is possessed? Are strange things happening in there?  Maybe you’ve just been away for awhile. Even dedicated hobbyists can get a bit rusty when life comes between them and their hobby. Maybe all you need is a quick refresher on some tools and techniques. Ready? Let’s begin with definitions. Slotting and slitting saws blades have a specialized purpose. These tools make deep and narrow cuts. Use a slotting saw to slice material from stock. Slitting saw arbors are the tool holders that keep the slitting saw blade on the spindle. Slitting saws and slotting saws do a better job than endmills when it comes to cuts that are deeper than wide. See, isn’t it all coming back to you? Nothing to be afraid of here.

Always  Buy the Right Blades

Don’t buy garbage because it is cheap. You will only lose money over the long haul. Always start with the number of teeth on a blade. Go with a high tooth count to get a clean, finished cut.

Always choose the right blade material for the job you are doing. Slitting saw blades are usually made from carbide or high speed steel.

Next, go with the thickest saw blade the operation can handle. Thicker blades mean more stability. Stability means rigidity. You want rigidity in all times and places.

Now, select the right blade size. Most slitting saws have a 3” to 4” in diameter. If you go big, you will go home with run out, wobbling, and staggering. All bad things.

Use Proper Feeds and Speeds

Feeds and speeds are always important. But, working with a slitting saw is literally a make or break operation. Get it wrong and trash the blade. All cuts are precise, but slitting cuts are extra, super precise. Pick software that handles slotting and slitting saw cuts. The wrong feed and speed setting will destroy your slitting blade faster than Godzilla destroyed Tokyo.

One Pass or Two?

There are two techniques for making deep cuts. With one approach, you make a series of multiple cuts.  Start shallow and then cut progressively deeper. Another way is to dig in and make the full cut in one single pass.  The single pass method avoids the problem of chips that don’t clear and then foul the blade on the next passes. But, if you just program the right feeds and speeds and use plenty of fluids, this shouldn’t be a problem. Seasoned machinists use a series of cuts.

slitting saw arborsAlways Use Quality Slitting Saw Arbors

Every machinist must deal with chatter. Manual machinists deal with chatter. CNC’ers deal with chatter too. It really doesn’t matter the source of the chatter. Whether it is chatter is from the tool or chatter from the work, how you deal with chatter is what matters. By the way, this isn’t the chatter during smoke breaks or the banter in the lunch room. This is the resonance caused when either the tool or the piece  vibrates. Don’t be so quick to blame the tool, the workpiece, or the machinist. Blame physics. Chatter is physics in action. You get chatter at all speeds and with all materials. It’s a bigger problem the faster you machine. A good machinist knows that chatter must be vanquished.

Workpiece Chatter

You get workpiece chatter when the wall of your work starts to vibrate. Minimize this by maintaining as much rigidity as possible in workpiece for as long as possible.

Remove less material in each pass and make more passes.  The CNC Cookbook recommends upping rigidity by adding a material that is easily removed once the work is done.  They go as far as recommending a mixture of petroleum jelly and lead shot! Additive manufacturing to achieve subtractive manufacturing. What a concept!

Workpiece chatter is more of a problem when you literally cut corners. The geometry of the engagement increases the number of teeth in the cut. This increases the cutting forces and causes chatter.  Use a larger initial radius to make the first cut, and then remove the remaining stock in another pass.

Machine Chatter

The machine is the home sweet home of chatter.  The machine, the tool holder, and the tool are all sources of chatter problems. These parts want to naturally vibrate.  Don’t let chatter limit your machining. Your only limits should be the limits of your machine, your tool, and your material.  Here’s some things to keep in mind in reducing chatter.

Speed.  Instinct makes you want to go slower.  Fight that urge. Speeding up might be the right.  If chatter starts, speed up. That sweet spot is probably higher; not lower.  Create a Stability Lobe Diagram to help. Get help from companies that specialize in analyzing your tooling equipment and creating the diagram for you.
