Use tungsten carbide burrs on hard materials including steel, aluminum and surefire, all kinds of stone, ceramic, porcelain, real wood, acrylics, fibreglass and reinforced plastics. When suited for soft metals including gold, platinum and silver, carbide burrs are perfect because they can last for some time without breaking or chipping.

Different cuts of carbide burrs will probably be best suited for several materials.

Purposes of SB-3 Carbide Burr Die Grinder Bit
Use carbide burrs in air tools for example die grinders, pneumatic rotary tools and speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools for instance 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 widely-used in the aerospace, automotive, dentistry, stone and metalsmith industries.

What SB-3 Carbide Burr cut if you choose?
Single cut (one flute) carbide burrs possess a right handed (up cut) spiral flute. Single cut is used with stainless-steel, hardened steel, copper, cast iron and ferrous metals and definately will remove material quickly having a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Heavy removal 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 for all non-metal materials including stone, plastics, real wood and ceramic. This cut has more cutting edges and may remove material faster. Double cut also called Diamond Cut or Cross Cut (2 flutes cut across the other person) and may leave a smoother finish than single cut on account of producing smaller chips because they cut away the information. Use double cut for medium-light stock removal, deburring, finishing and cleaning. Double cut carbide burrs are hottest and help most applications.

What SB-3 Carbide Burr RPM speed should you use?
The velocity of which you employ your carbide burr with your rotary tool is determined by the material you’re using it on and the contour being produced but it’s reliable advice you no longer need more than 35,000 RPM. If the burs are chipping easily this might be due to the speed being not fast enough. It’s ideal to begin the bur off slow, enhancing the speed in the process. High speeds minimizes clogging in the flutes of the carbide burs.

As with most drill bits and burrs, allow the burr carry out the work and apply merely a little pressure, otherwise the cutting edges from the flutes will chip away or become smooth too soon, lowering the lifetime of your burr.
