What is a Tungsten Carbide Burr Die Grinder Bit?
What is a Tungsten Carbide Burr Die Grinder Bit? Tungsten Carbide burrs can be used on most hard materials: metals including steel, aluminum and cast iron, all types of stone, ceramic, porcelain, hard wood, acrylics, fibreglass and reinforced plastics. When used on soft metals such as gold, platinum and silver carbide burrs are ideal as they will last a long time with no chipping or breaking.
Steel, Carbon Steel & Stainless Steel
Gold, Platinum & Silver
Ceramic & Porcelain
Plastic, Carbon Fiber Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Different cuts of carbide burrs will be best suited to certain materials
What do you use Carbide Burrs on?
Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools and high speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel. Always use a handpiece that runs true i.e with no wobble.
Who uses Carbide Burrs?
Carbide burrs are widely used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And are used in the aerospace, automotive, dental, stone and metal sculpting, and metal smith industries to name but a few.
What speed should be used on Carbide Burrs?
The speed at which you use your carbide bur in your rotary tool will depend on the material you’re using it on and the contour being produced but it’s safe to say you do not need to exceed speeds of 35,000 RPM.
If the burs are chipping easily this could be due to the speed being too slow. However, it’s ideal to start the bur off slow, increasing the speed as you go along. High speeds will prevent clogging in the flutes of your burs.
