* High quality China made 90 degree cone shape carbide rotary burrs die grinder bits.
* 90° cone shape carbide burrs on 1/4" Shank. Our carbide burrs we manufacture here in the China are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the tungsten carbide, they can be used on much more demanding jobs than High Speed Steel.
* Diameter: 1/2", Length of Flute: 1/4", OAL: 2 1/4"
* Cut Type: Double Cut.
Product Features and Applications
* 90° cone shaped carbide rotary burrs on 1/4" Shank.
* Double cut allows for rapid stock removal in harder materials. The addition of the left hand flutes reduces the pulling action, allowing better operator control. It reduces the size of the chips and can be used at slower than normal speeds. Used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as stone, plastics, hard wood and ceramic. They have more cutting edges and will remove material much faster.
* Double cut will leave a smoother finish than single cut due to producing smaller chips as they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning. Designed for medium- light removal of material, deburring, fine finishing, cleaning, smooth finish, and creating small chips.
* Uses: Carbide burrs are widely used in metalworking, tool making, engineering, model engineering, wood carving, jewelry making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. Carbide burrs can be used in the aerospace, automotive, dentistry, stone and metalsmith industries.
* Suggested RPM Speeds: The speed that you use your carbide burr in your rotary tool will depend on the material you're using it on and the shape being produced, but typically you do not need more than 35,000 RPM. If the burrs are chipping easily, this could be due to the speed being too slow. We suggest starting the burr off slow, and increasing the speed as you go along. High speeds will prevent clogging in the flutes of your carbide burrs. As with all drill bits and burrs, let the burr do the work and apply light pressure, otherwise the cutting edges of the flutes will chip away or become smooth too quickly.
