ROTARY BURR DEBUR & GRIND
Rotary burr products come in various shapes and sizes. It’s important to buy a selection of different shaped tools to get the best use out of them. A simple way to help you decide which burrs to purchase is to consider the material you work with. Combined with the shape of that material you can then decide on which rotary burr products are the most appropriate for your workshop.
The end result you are after will determine the type of rotary burr to use. Similarly what type of shank you require is another decision to consider. Shanks come in different sizes at different lengths for use on drill presses and portable drills. Usually a rounded 6mm or hex shank are your options. The most common shapes of carbide burrs are the ball, tree, inverted cone, pointed cone, ball nose and rotary burr with end cut. They all differ from one another in terms of purpose.
Cylindrical carbide burrs with end cuts, in particular, are ideal for contour finishing or surfaces with curved edges. The end cut on the rotary burr allows your drill to reach areas with angles to ensure you’re able to achieve the best grind.
This cylindrical rotary burr with end cut is made with tungsten which is commonly used in heavy metal alloys. The tungsten carbide has a grading of K20, meaning it can withstand high impact with other hard metal surfaces such as alloy and stainless steel. It also has a double-cut type that provides additional cutting edges to the product. This cut assists the removal of material faster than using a single-cut type grinder. The product also features left-hand flutes. Left-hand flutes reduce the pulling action of the grinder giving you better control of the machine. Reducing the size of the chips on the material helps achieve superior results.
Moreover, you can adjust your grinder at a lower speed and still be able to achieve the finish you require using these cylindrical tools.
