Carbide burs are among the most favored and versatile cutting tools employed in virtually any industry. Constructed from Tungsten Carbide they’re primarily utilized to remove burrs (the tiny flakes of metal) that always stay with the task piece after the machining process. Burs can be bought in standard lengths long series (for tough to reach applications) plus miniature sizes (for use in pencil grinders).

Features
Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but you are more brittle and should be used with rigid tool holding systems
Uncoated tools feature only the base substrate without the additional treatment or coatings and therefore are suited to a wide range of applications
Round shanks allow use which has a wide selection of tool holding systems
Double-cut style has rows of cutting teeth decline in two intersecting directions for fast material removal plus a rougher finish
For deburring, interior contour work

CUT TYPE

Singlecut
General purpose tool for certain, copper, brass and steels
Fairly aggressive cutting action, with good material removal rates
It leaves a good finish of many all materials, though the bite could be demanding on operators

Doublecut
For general purpose use including surefire, copper, brass and steels
The Doublecut works with a cross flute of exactly half the number of standard flutes within a opposing helix
Sliver dimensions are reduced, out of the box the operator fatigue from the balanced cutting forces
Lower RPMs could be utilized with little negative effect on performance
The decreased load equates to operator’s often feeding it more aggressively

Alumacut
Ideal for all non-ferrous, non-metallic workpieces like aluminum, zinc, plastic, wood, etc.
A very aggressive cutting action, with minimum possibility of plugging these flutes up

Diamondcut
Can be a finer cut of opposing helixes
Operating control is excellent because the biting action is bound as they are the silver size made out of it
This version is usually preferred to get where titanium and other difficult materials (superalloys) are deburred
With all the teeth being smaller and slightly more fragile as a result, tool life’s not commonly a couple of import

Fiberglass has a tendency to cut nicely with Diamondcut

Chipbreaker
Another type of the Doublecut, this can be a slightly less aggressive tool whose main objective is usually to simply interupt the cut

One single, opposing helix is ground within a spiral round the tool, typically
Silver size falls, surface finish decreases marginally, hand control rises, marginally
