Double Flat Bottom Silver Welding Flutes Tungsten Carbide Rotary File Burr
Tungsten carbide burr provides a method of deburring, shaping and chamfering internal grooves using a die grinder. We provide various shapes to facilitate different tasks. We also provide 2 grades to suit different metals. Most are "hard metal" grades, very suitable for steel, stainless steel and cemented carbide. The "non-ferrous" grades have a smaller range of options, and are more suitable for bronze, aluminum alloy and brass. They are also effective on wood and are very helpful for carving.
Drive tool:
