Carbide burs are probably the most in-demand and versatile cutting tools used in just about any industry. Made of Tungsten Carbide they are primarily used to remove burrs (the little flakes of metal) that frequently stay on the work piece after the machining process. Burs can be purchased in standard lengths long series (for hard to reach applications) as well as in miniature sizes (for use in pencil grinders).
Features
Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but they are more brittle and ought to provide with rigid tool holding systems
Uncoated tools feature only the base substrate without additional treatment or coatings and so are ideal for many applications
Round shanks allow use with a wide array of tool holding systems
Double-cut style has rows of cutting teeth cut 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 higher material removal rates
This tool leaves a great finish of all all materials, but the bite could be demanding on operators
Doublecut
For general purpose use including iron, copper, brass and steels
The Doublecut relies on a cross flute of exactly half the volume of standard flutes within a opposing helix
Sliver dimension is reduced, as they are the operator fatigue from the balanced cutting forces
Lower RPMs could possibly be utilized with little negative impact on performance
The decreased load compatible operator’s often feeding it more aggressively
Alumacut
Best for all non-ferrous, non-metallic workpieces like aluminum, zinc, plastic, wood, etc.
A very aggressive cutting action, with no chance of plugging these flutes up
Diamondcut
Can be a finer cut of opposing helixes
Operating control is superb as the biting action is limited as they are the silver size created from it
This version is usually preferred to get where titanium as well as other difficult materials (superalloys) are deburred
Together with the teeth being smaller and a little more fragile consequently, tool life’s not usually a matter of import
Fiberglass will cut nicely with Diamondcut
Chipbreaker
Another type of the Doublecut, it is a slightly less aggressive tool whose main objective is usually to simply interupt the cut
A unitary, opposing helix is ground in a spiral around the tool, typically
Silver size decreases, surface finish goes down marginally, hand control rises, marginally
