Use tungsten carbide burrs on hard materials including steel, aluminum and cast iron, various stone, ceramic, porcelain, wood floor, acrylics, fibreglass and reinforced plastics. When suited for soft metals like gold, platinum and silver, carbide burrs are fantastic while they last for years with no breaking or chipping.

Different cuts of carbide burrs will likely be best suited for sure materials.

Uses for SB-3 Carbide Burr Die Grinder Bit
Use carbide burrs in air tools including die grinders, pneumatic rotary tools and also speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.

Carbide burrs are traditionally used for metalworking, tool making, engineering, model engineering, wood carving, making jewelry, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. Carbide burrs are utilized from the aerospace, automotive, dentistry, stone and metalsmith industries.

What SB-3 Carbide Burr cut should you?
Single cut (one flute) carbide burrs have a very right handed (up cut) spiral flute. Single cut is utilized with stainless, hardened steel, copper, iron and ferrous metals and can remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Heavy elimination of material
Milling
Deburring
Cleaning
Creates long chips

Use double cut carbide burrs on ferrous and non ferrous metals, aluminium, soft steel as well as all non-metal materials including stone, plastics, real wood and ceramic. This cut has more cutting edges and can remove material faster. Double cut otherwise known as Diamond Cut or Cross Cut (2 flutes cut across the other person) and may leave a smoother finish than single cut due to producing smaller chips while they cut away the fabric. 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 removing material
Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips

What SB-3 Carbide Burr RPM speed the use of?
The velocity from which you employ your carbide burr with your rotary tool will depend on the pad you’re using it on and the contour being produced but it’s safe to assume you don’t need over 35,000 RPM. If your burs are chipping easily this may be as a result of speed being not fast enough. It’s ideal to begin the bur off slow, increasing the speed as you go along. High speeds may prevent clogging from the flutes of the carbide burs.

As with most drill bits and burrs, permit the burr perform the work and apply only a little pressure, otherwise the cutting edges from the flutes will chip away or become smooth too quickly, minimizing the time of your burr.
