Carbide burs are probably the most widely used and versatile cutting tools utilized in practically every industry. Manufactured from Tungsten Carbide these are primarily utilized to remove burrs (the tiny flakes of metal) that always stay on the job piece as soon as the machining process. Burs are available in standard lengths long series (for hard to reach applications) and in miniature sizes (to 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 should be used with rigid tool holding systems
Uncoated tools feature exactly the base substrate with no additional treatment or coatings and they are suitable for an array of applications
Round shanks allow use with a wide variety of tool holding systems
Double-cut style has rows of cutting teeth cut 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 good material removal rates
This tool leaves a nice finish on most all materials, nevertheless the bite can be demanding on operators
Doublecut
For general purpose use including certain, copper, brass and steels
The Doublecut relies on a cross flute of exactly half the amount of standard flutes inside a opposing helix
Sliver sizing is cut down tremendously, as is the operator fatigue from your balanced cutting forces
Lower RPMs could be utilized with little negative affect performance
The decreased load compatible operator’s often feeding it more aggressively
Alumacut
Great for all non-ferrous, non-metallic workpieces like aluminum, zinc, plastic, wood, etc.
An exceptionally aggressive cutting action, with little if any potential for plugging these flutes up
Diamondcut
Is really a finer cut of opposing helixes
Operating control is very good as the biting action is fixed as they are the silver size produced from it
This version tends to be preferred to acquire 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 commonly a few import
Fiberglass tends to cut nicely with Diamondcut
Chipbreaker
Another type of the Doublecut, this is the slightly less aggressive tool whose main purpose is usually to simply interupt the cut
A unitary, opposing helix is ground in the spiral throughout the tool, typically
Silver size decreases, surface finish decreases marginally, hand control rises, marginally
