Long shank carbide burrs are common in air tools. They include hobby rotary tools and pneumatic rotary tools. Besides, others are high-speed engravers and die grinders. So, it means that it is vital to have the correct shank size of the burr.
This article explains how to use long shank carbide burrs for successful metalwork. Whether for engineering, carving, chamfering, or any process that you need them for, long shank burrs have some benefits. Browse below to learn more!
What Is the Meaning of Shank in Carbide Burrs?
A shank in carbide burrs is the section of the burr that a craftsman inserts into the router. It could be on a rotary or any other tool that accepts burrs for use. In a carbide burr, the shank will be the specific part that the chuck will hold onto to remain intact.
There has been a remarkable evolution in the designs and types of shanks. Of them all, there are a few standard models that engineers and designers use. Some of them are straight, hex, SDS, brace, triangle, and morse-tapered shanks.
Where Do You Need to Use Long Shank Carbide Burrs?
Most deburring applications need long shank carbide burrs for the best results.
Depending on your application, you might need the shanks in various sizes. The shapes and styles differ as well.
The good news about these long-shank carbide burrs is that you can re-sharpen them. Also, you can shorten them using a hacksaw.
The best place to use long shank carbide burrs is when using a well-maintained grinder. It should be handheld. Before starting your grinder, stabilize your shank. You can do this by checking it against your workpiece.
Besides, always use protective gear on your eyes, face, and ears. The long shank carbide burrs are available in two fluting styles. These are single cut and double cut.
Single cut long shank carbide burrs are for general purpose. They offer moderate stock removal. Moreover, their use is in milling, deburring, finishing, and cleaning applications. These result in long chips.
Likewise, double-cut long shank carbide burrs offer effective stock removal. These are for cleaning, finishing, and deburring applications. Besides, these result in small chips for an excellent finish. They boast excellent operator control.
How to Use Long Shank Carbide Burrs?
First, this step-by-step guide shouldn’t replace the hands-on training that you should undergo. We insist that you should follow all safety procedures.
This section takes you through the steps of using long shank carbide burrs from start to finish.
Carbide burrs are common materials in workshops. It will be most important to use them when considering safety.
Step 1: Select Your Long Shank Carbide Burr
Know the size of the shank you would want to use. That’s because the diameter of your shank matters. Thus, it should match that of your screws. There are different types of shanks. Each might need you to drill a different type of hole for it to fit well.
Step 2: Put the Chosen Long Shank Carbide Burr into the Grinder
Loosen your grinder’s chuck. Depending on the model and design you have, you can twist it anticlockwise and widen its mouth. Insert your shank into its jaws and tighten it well. It should be intact and not wobbling.
Step 3: Check All Essential Settings
It is one of the primary steps to ensure that your project runs well. Ensure that you connect the grinder to a power source and it is functional. Low power will make you work slower.
Check its speed setting. You will most often be using a faster setting. Also, confirm the direction you intend to work in at the moment.
Moreover, you can run the grinder slower and look at how the grinder moves during the test. Check whether it is the correct one for your project.
Step 4: Place Your Material
Ensure that the material you intend to use is secure and in a sturdy area. You can secure it with a vice or clamp. If you want cleaner edges, you can clamp scrap wood under your material.
Always check if you have enough clearance space to avoid any accidents.
Step 5: Start the Work
So, it is the point where you will begin working on your project. Everything should be well set for you to use the long shank carbide burr as you need. Angle the shank well to avoid damaging it.
Even if you create a mess, you can shorten the shank using a handsaw. Of course, it depends on whether your tool has this provision. But, it is better to be keen to avoid wasting a part of the shank.
You can speed up and slow the grinder when the need arises. Apply the correct pressure where necessary until you finish the task.
Speed and overheating are some of the concerns of using long shank carbide burrs. Ensure that you free-run your burr every several minutes. That’s because it helps to maintain a cooler temperature on the burr and prevents overheating.
For efficient use of the carbide burr, ensure that you maintain working at a higher speed. When at high speeds, there is a low chance of chips.
It will be easy for the burr to cut well in pockets and corners. What’s more, it reduces instances of bouncing, jamming, and wedging.
Step 6: Do Some Finishing and Clean Up Work
If the material you are working on doesn’t have cleaner edges, work on it for a fantastic finish and a cleaner look. You could use the procedure above to re-work with your long shank carbide burr if there was much left to do.
Once you finish the project to your satisfaction, remove the shank from the grinder. Return to where it should be for safety. Vacuum the working surface to remove all the dust and chips.
Safety Notes to Follow When Using Long Shank Carbide Burrs
Long shank carbide burrs are becoming a favorite in many workshops. Depending on where you use them, they can last longer with no breaking or chipping. But, are you aware of the precautions and safety measures to take while using them?
Remember that this is not a shortcut to hands-on training. These are safety measures to remind you of the standards in the work area that you should follow.
You will most often be using carbide burrs at very high speeds. The guidelines below will help you reduce burr fatigue and user errors.
#1. Before turning on your power tool, you should be very cautious about how you place the long shank carbide burr. The burr MUST be in contact with your workpiece.
#2. Check that it is well secured and intact. Any wobbling will result in accidents or unsatisfactory results. Please insert it into the slot or bore and check that it fits well.
#3. The carbide burr should ALWAYS remain in complete contact with your workpiece. Ensure this anytime the machine will be running. Don’t loosen it whatsoever.
Otherwise, you will experience bends on the shank. The worst will be deadly accidents as the burrs will be at very high speeds.
#4. Ensure that you don’t exceed the highest idling speed. It is if you are skeptical about the contact of the carbide burr and the workpiece.
#5. When the shank is in contact with your workpiece, the application’s top speeds need to be minimum. It should be lower than the usual speed of these burrs when using them on standard shanks. It lets you be on the safer side without risking bends and accidents.
Final Thoughts!
Long shank carbide burrs can be tricky to use, especially if you are new to metalwork. We expect that you have the best training before attempting any tasks with carbide burrs. Also, ensure that you follow all the precautionary measures and safety guidelines.
It prevents waste of material and any accidents. Besides, one of the concerns of working with long-shank carbide burrs is speed and overheating. Ensure that you use the right amount of pressure when you reduce the speed of the grinder.
You will prevent overheating and chipping. These can reduce the longevity of the carbide burr. Above all, make sure you buy long-shank carbide burrs from a reliable carbide burr manufacturer. So, it ensures your carbide burr offers the best performance and also lasts longer.
