Carbide burs are probably the most widely used and versatile cutting tools used in just about any industry. Made of Tungsten Carbide they’re primarily utilized to remove burrs (the little flakes of metal) that usually stay with the job piece as soon as the machining process. Burs can be bought in standard lengths long series (for challenging 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 they are more brittle and must be utilized with rigid tool holding systems
Uncoated tools feature exactly the base substrate with no additional treatment or coatings and are ideal for a variety of applications
Round shanks allow use with a wide range 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 good material removal rates
This tool leaves a good finish of many all materials, though the bite can 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 in a opposing helix
Sliver dimension is cut down tremendously, out of the box the operator fatigue through the balanced cutting forces
Lower RPMs could possibly be utilized with little negative effect on performance
The decreased load compatible 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 no chance of plugging these flutes up
Diamondcut
Is a finer cut of opposing helixes
Operating control is very good since the biting action is fixed as they are the silver size produced from it
This version is usually preferred in shops where titanium and also other difficult materials (superalloys) are increasingly being deburred
Using the teeth being smaller and more fragile as a result, tool life’s not often a few import
Fiberglass is likely to cut nicely with Diamondcut
Chipbreaker
Another sort of the Doublecut, it is a slightly less aggressive tool whose main objective is always to simply interupt the cut
One single, opposing helix is ground in the spiral round the tool, typically
Silver size falls, surface finish decreases marginally, hand control rises, marginally
