Carbide burs are probably the most favored and versatile cutting tools used in just about any industry. Manufactured from Tungsten Carbide they are primarily employed to remove burrs (the small flakes of metal) that usually remain on the work piece after the machining process. Burs are available in standard lengths long series (for hard to reach applications) along with 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 must supply with rigid tool holding systems
Uncoated tools feature only the base substrate without additional treatment or coatings and therefore 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 decline in two intersecting directions for fast material removal and a rougher finish
For deburring, interior contour work
CUT TYPE
Singlecut
General purpose tool for iron, copper, brass and steels
Fairly aggressive cutting action, with higher material removal rates
This tool leaves a pleasant finish on many all materials, though the bite might be demanding on operators
Doublecut
For general purpose use including cast iron, copper, brass and steels
The Doublecut works with a cross flute of exactly half the number of standard flutes within a opposing helix
Sliver sizing is cut down tremendously, as is the operator fatigue from the balanced cutting forces
Lower RPMs might be utilized with little negative influence on performance
The decreased load equates to operator’s often feeding this tool more aggressively
Alumacut
Great for all non-ferrous, non-metallic workpieces like aluminum, zinc, plastic, wood, etc.
An extremely aggressive cutting action, with little if any probability of plugging these flutes up
Diamondcut
Is a finer cut of opposing helixes
Operating control is excellent because the biting action is limited out of the box the silver size produced from it
This version tends to be preferred to get where titanium and also other difficult materials (superalloys) are deburred
Together with the teeth being smaller and slightly more fragile as a result, tool life is not often a couple of import
Fiberglass tends to cut nicely with Diamondcut
Chipbreaker
Another version of the Doublecut, this is a slightly less aggressive tool whose main purpose is always to simply interupt the cut
A single, opposing helix is ground within a spiral round the tool, typically
Silver size falls, surface finish goes down marginally, hand control increases, marginally
