There’s a common problem with everything on earth that spins. In machining, we call this problem runout. It’s the inaccuracy of anything that spins. That’s because the tool or shaft doesn’t turn with perfect alignment to its main axis. It’s a common problem. But, it’s also a huge problem. For 5C collets, a simple collet wrench solves the problem.
TIR Measures Your Accuracy
Are you accurate? When your drill chuck can’t hold the drill bit in the center, as it turns, it turns on a secondary axis. Meet runout. Total indicator runout (TIR) measures the concentricity of the collet. It’s how you measure accuracy and runout. Just place a dial indicator against the rotating bit. The tool amplifies all minute variations, enough for you to see them with the naked eye. Basically, it is a magnifier. It just makes the very slight deviation from true concentricity big enough for you to see and measure. You must measure to make adjustments. That’s because you’ll never adjust what you never measure. Naturally, you can’t measure what can’t be seen. Once you can see and measure, you can adjust.
Try something as simple as cleaning. Open the jaws and blow out with compressed air. Just a small bit of debris could be the cause of the problem. Then check the drill rod and verify it is still true. Take time to verify the runout on the spindle as well as checking the bearings on the spindle.
Correcting Brake Lathe Runout
Taking care of the arbor is taking care of runout. Every once and awhile, check the spindle and arbor. Look for metal chip buildup or rust. Clean your arbor with fine steel wool and some WD40. Don’t use sandpaper or a wire brush. Removing metal makes the runout worse. While you’re at it, inspect the spindle bearings. When the lathe is properly set up and the arbor looks good, this is probably the runout source.
Use a Collet Wrench and Protect Your Collets
An ounce of prevention is worth a pound of cure. In other words, the simplest way to correct runout is to prevent it. Runout happens with collets that aren’t properly tightened. Runout can ruin the collet.
Use a collet wrench to tighten all three jaws evenly. Just align the prongs into the collet. Now simply turn the wrench. That threads the collet in the machine.
See, its easy. You didn’t do it because you didn’t know. Now you know. So, what are you waiting for, a collet wrench? That’s easy too.

Runout. It’s the bane of everything in the world that spins. Including our world (Earth) itself. Runout refers to the inaccuracy of any mechanical system as it spins. It happens when the tool or shaft doesn’t turn in complete alignment with the main axis. It might be a common problem, but it causes really big problems in machining. With 5C collets the solution is a simple collet wrench.
When the drill chuck doesn’t hold the bit in the center, the bit turns on a secondary axis as it rotates. Like a wobble. This is runout. Total indicated runout (TIR) is how you measure the concentricity of a collet. It’s not hard to do. Just press a dial indicator against the rotating bit after it starts turning. The dial indicator amplifies any minute variations, so they can easily be seen with the naked eye. The dial indicator just takes the slight deviation from true concentricity and makes it large to see and measure. Since you can’t make adjustments to what you can’t measure and you can’t measure what you can’t see, the dial indicator solves this problem. The deviations become visible and thus correctable. Make sense?
Start with a good cleaning. Many times this solves the problem. Fully open the jaws and blow them clean with compressed air. Just one speck of dirt can cause runout. Next, check the drill rod to make sure it is true. While you are at it, check the runout on the spindle and check the bearings on the spindle.
Fix Brake Lathe Runout
This revolves around arbor care. Yes,the pun was intended. Just inspect the arbor and spindle every once in a while. Look for metal chip buildup or rust. Simply clean the arbor with fine steel wool and some WD40. Don’t use sandpaper or a wire brush. If you accidentally remove some metal when you clean, the runout only gets worse. When you check the arbor take a look at the spindle bearings. That could be the source of the runout if you verify lathe setup and arbor condition.
Instead of correcting runout, prevent it. When collets aren’t properly tightened you get runout. Runout can also damage the collet.
Use a collet wrench and tighten all three jaws evenly. Just align the three prongs into the top of the collet. Next, turn the wrench to thread the collet into your machine.
So buy a collet wrench and stop runout.

Edgar Cayce was an American psychic. He fell into a deep trance and began to make predictions. Someone gave him the name the “Sleeping Prophet.” He said many things while he was in this sleeping state. Did he say anything about the collet wrench? Maybe he did!
Dealing with Difficult Relationships
Cayce predicted that difficult relationships would arise. He counseled that these difficulties are an opportunity to grow in this life and the next. You just need a tool to help through those difficult times. Could the tool he recommended be a collet wrench?
Face it, you probably have a love/hate relationship with your mill. Sometimes everything sets up right and sometimes setup gives you a fit. But with a collet wrench in hand, you get just the right amount of torque on the collet for the best hold. Maybe Cayce prophesied the difficult relationship you can have with your collets and saw the collet wrench as a tool to help.
In reading 4666, Cayce predicted the electric motor that powers mills and lathes today. Honestly, when is the last time you had to add diesel to your machine?
You will have before you the gasless motor invented
Now granted, Cayce did live until 1945. That was plenty of time to see electricity and electric motors become commonplace. Wonder if while he was dreaming of motors that ran without gas if he dreamed of the lathes and mills operated by these motors? If so, surely he knew that the collet would be the preferred method of tool holding, and collets need collet wrenches. This means he must have predicted the collet wrench!
Cayce predicted that cataclysmic events would change the face of the Earth forever. On August 11, 1936 he asked about changes that might happen with the start of a new millennium (2000 or 2001). He responded
When there is a shifting of the poles a new cycle begins.
Well that’s been about 17 or 18 years. There are scientists that believe that about that time, the North and South Poles started to shift. No joke. It’s happened before. They say when it happens, its bad.
So just in case he was right, you should probably get your collet wrench now. That way you have time to use it before the end is near. Cayce didn’t prophsey about where to find a good collet wrench, but if he had, he would have said The Tool Company.
Cayce appreciated quality. He’d predict the best quality collet wrench would be made in the USA. Even then, he was suspicious of goods made in China.
Get your Armageddon-proof collet wrench from The Tool Company now. The design made by Sierra American Multi-systems has a concave face that aligns perfectly. The handle is sturdy, durable and easy-to-find. So, follow the lead of the sleeping prophet and buy your collet wrench today.
*Edgar Cayce didn’t really predict the collet wrench. His dictated prophesies while in a trance and many of them were so vague you can manipulate them to mean almost anything. Most of the predictions in this blog are pure fiction. But CNC machining is based on hard physical science. You need serious equipment (tool tray, saw arbor, collet wrench) like you find at The Tool Company. We’ve made what you need when you mean business.
January can be kind of a cold, dreary and dull month. The holiday season has passed and life settles back into a routine that can almost feel like a rut. So, let’s spice things up with an impromptu celebration. Let’s recognize American manufacturing and the collet wrench. Why not? January needs some life. The economy is up. We see signs of growth in American manufacturing as well. Since your collet wrench is a tool that makes your life easier and your balance sheet healthier let’s celebrate it as well.
Time spent tooling isn’t time spent on machining. You want to work as efficiently as possible. A collet wrench makes you a quick change artist. Remove 5C or R8 collets from the nose of your mill easily and quickly. You’ll get just the right amount of torque. Collets have low runout (natural deviation caused by spin of tool). Runout is costly. If you want a healthy bottom line, you must find ways to control runout. Decrease runout with collets, and decrease wasted motion by using a collet wrench. Sound simple? It is! Grab your collet wrench and celebrate.
Celebrating American Manufacturing
While you are celebrating, don’t forget the American manufacturing economy that continues to recover. Forbes predicts continued growth for 2018 and even more gains in 2019. Changes in tax laws has many companies repatriating dollars to the US. That’s certainly something to celebrate. Growth will continue in the oil and petrochemical sectors. If you machine parts for these sectors, the future looks bright.
Need to purchase new machinery? 2018 might be a good year. Because capacity utilization is low, it’s a great time to shop equipment. Its a good time to shop financing as well.
American manufacturing is making a comeback and The Tool Company is proud to play a supporting role. We sell the collet wrenches, saw arbors, multistops, and tool trays you need. Everything we sell is also made in the USA.
So, don’t let January get you down. Create something new. Try a new technique. Celebrate little things like your collet wrench and big things like a growing economy and the resurgence of American manufacturing.

There are two choices for tool holding or work holding: chuck or collet. While collets may be chucks, they are still different. The collet wrench gets close and personal with your collets every day. So, let’s see which the collet wrench thinks is better.
Collet Advantages vs The Chuck Advantage
The collet wrench assesses performance. It sees that chucks don’t perform as well as collets. They are not as centered or balanced as a collet. If you use a collet over a chuck you will get less wobble and less run out. That’s because collets use a design that is reliable, durable and versatile. Use collets to hold work or use them to hold tools.
The collet wrench also knows the short-coming of collets. They can’t handle a wide range of sizes. A chuck with a 3-jaw design can accommodate a wide range of sizes. But that is the only advantage of a chuck. Collets offer better speed and accuracy and that leads to more productivity. Advantage: collet!
Collets are Fast
The collet wrench knows physics as well. They always recommend collets for turning at high spindle rpm. A chuck takes longer to accelerate because its mass is greater. Longer acceleration times equals longer cycle time. Longer cycles time reduces productivity. Even collet wrenches know that less productivity is not a goal.
Doubling the spindle speed quadruples the centrifugal force. That centrifugal force pulls the chuck jaws out. Now you’ve reduced the clamping force. Centrifugal force doesn’t effect collets. You get the same tool holding or work holding force no matter the speed.
That’s because a collet applies force around the entire circumference area. A chuck just applies force at the contact areas. A collet wrench knows this, do you? Because the collet exerts force over the entire circumference area, it applies even holding force.
Collets open and close fast too. Much faster than a chuck. You can change collets quick. Collets increase time spent machining and decrease time spent setting up. Increased productivity is the goal.
Want to change even faster? Get the right collet wrench.
Quality Collet Wrench
A good R8 or 5C collet wrench makes it easy to insert or remove collets from the spindle noses of CNC turning machines. A good, sturdy model has 3 metal prongs to grip your collet. It should also fit your hand.
- designed with a concave face for perfect alignment
- made from high impact plastic with a steel insert
- bright fluorescent orange
- tapered for comfort in the hand and ease of use
Trust your collet wrench and use collets over chucks. Don’t have a collet wrench? Buy one today.
Most CNC machinists started machining in a school shop class or a hobby shop. This is where they learned to screw collet chucks into a knee mill. Collet holding is a simple concept. That’s why it is an early lesson. Collets give you excellent symmetry in tool holding. They reduce vibration. This makes them the perfect tool holder for high speed milling. A perfect tool holder deserves the perfect tool. A collet wrench is the perfect tool for your collets.
Collets are just a set of concentric wedges that apply force to the tool shank to hold it is place. The more force you apply to the collet, the more force clamping the tool. According to Engineering.com the runout characteristics of collet clamping are 10 times better than other styles of tool holders like side locking tool holders.
Centrifugal force comes into play as the tool and tool holder spins. The centrifugal force gets higher as you mill faster. So, if the mass of the tool and holder is not balanced, the faster it spins the out of balance it becomes. Motion on a curved path represents an accelerated motion and requires a force directed at the center of the path. This force is centripetal force. In physics the formula is:
Centripetal force = mv2/r
m = the offset center of mass from the spin axis
v = rotational speed
r = radius of the toolholder/tool assembly
If a set screw is off even slightly, the result is vibration at high speeds. High speed machining demands symmetry. You get symmetry with collet tool holding.
Torque and the Collet Wrench
Collets are the perfect tool holder for machining at high speeds and the collet wrench is the perfect tool for tightening collets.
To determine the optimal torque, check out Techniks handy torque chart. Make sure your collet is clean. Chips or cutting fluid on the inside of the collet keeps the collet from holding properly.
Make sure you use the perfect collet wrench. Remove 5C collets with ease from the nosepiece of your mill when you use a collet wrench.
The Tool Company sells a collet wrench made of high impact plastic molded for long life. It has a large, tapered handle for easy to use. It’s easy to hold and because it is bright fluorescent orange, it is easy to find.
Every tool, tray, and tool holder sold by The Tool Company is made in the U.S.A. Support American manufacturing and get a great collet wrench at the same time.

Do you ever think about your collets? Probably not. Even if you do, you probably don’t spend much time thinking about them. You probably even spend less time thinking about your collet wrench. You know your collets have an important job to do; but your collet wrench has a big job too. A good collet wrench can save time and money.
Collets are Essential
If you are operating a CNC machine you use collets. It’s just that simple. Collets are essential for tool holding.
Bridgeport Machines developed the R8 collets for tool holding with their machines. R8 collets are internally threaded and fit into the machine taper itself.
5C collets can be used as tool holders or work holders. They are externally threaded.
It doesn’t matter the name or the reason for your collet. What does matter is that the collet is secured properly. If your collet isn’t tight it will lead to vibration, chatter, ruined material, and destroyed tools.
Damaged cutters, damaged work; neither is a good thing. They are an unnecessary waste of valuable time and money.
Instead of wasting time and money; just make sure the cutter is tight. To get the right amount of torque don’t tighten by hand. To get it tight right, use a collet wrench.
Tormach, the equipment manufacturer ran tests to determine what it takes to pull a tool out of its collet. They discovered that one of the worst things you could do was to leave the protective oil coating found on new cutters. Removing the oil and properly tightening from 20 ft lb to 40 ft lb resulted in an increase in holding power from 1300 lb to 3600 lbs.
So for your safety and to protect your tools, keep them clean and dry and tighten them properly with collet wrench. By the way, if you didn’t know that you should remove that protective coating; you know now.
The Tool Company sells quality tools, made in the USA. So its no wonder that the only collet wrench they sell is the high quality collet wrench made by Sierra American Multi-Systems. You know you can tighten your collets properly with a collet wrench from The Tool Company.
