Which Carbide Cut Should I Choose?
Choose Single Cut or Double Cut?
Single Cut Carbide Burr Cutting Tools
Single cut is a general purpose tool designed for cast iron, steel, some copper and brass and other ferrous materials. It will give good material removal and good workpiece finishes.
Double Cut Carbide Burr Cutting Tools
Double cut allows for rapid stock removal in harder materials. The addition of the left hand flutes reduce the pulling action, allowing better operator control.
Non-Ferrous Aluminum Cut Carbide Burrs
Non-ferrous are exactly what you would expect them to be. They are specially designed to be used on non-ferrous materials such as aluminum, copper and magnesium.
Our USA made tungsten carbide burrs can be used on most hard materials 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 perfect as they will last for a long time with no breaking or chipping.
Different cuts of carbide burrs will be best suited for certain materials.
Uses for Carbide Burr Tools
Use carbide burrs in air tools such as die grinders, pneumatic rotary tools and high speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.
Carbide burrs are widely used for metalworking, tool making, engineering, model engineering, wood carving, jewelry making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. Carbide burrs are used in the aerospace, automotive, dentistry, stone and metalsmith industries.
What cut should you choose?
Single cut (one flute) carbide burrs have a right handed (up cut) spiral flute. Single cut is used with stainless steel, hardened steel, copper, cast iron and ferrous metals and will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Heavy removal of material
Creates long chips
Use double cut carbide burrs on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as stone, plastics, hard wood and ceramic. This cut has more cutting edges and will remove material faster. Double cut also called Diamond Cut or Cross Cut (2 flutes cut across each other) and will leave a smoother finish than single cut due to producing smaller chips as they cut away the material. Use double cut for medium-light stock removal, deburring, finishing and cleaning. Double cut carbide burrs are most popular and work for most applications.
Medium- light removal of material
Creates small chips
What RPM speed should you use?
The speed at which you use your carbide burr in your rotary tool will depend on the material you’re using it on. If the burs are chipping easily this could be due to the speed being too slow. 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 carbide burs.
As with all drill bits and burrs, let the burr do the work and apply only a little pressure, otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your burr.
Our carbide burrs we manufacture 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 HSS (High Speed Steel). Carbide Burrs also perform better at higher temperatures than HSS, so you can run them hotter, and for longer. HSS burrs will start to soften at higher temperatures, so carbide is always a better choice for long term performance.
