Carbide burs are some of the hottest and versatile cutting tools utilized in virtually any industry. Manufactured from Tungsten Carbide they may be primarily used to remove burrs (the tiny flakes of metal) that frequently stick to the project piece after the machining process. Burs can be bought in standard lengths long series (for difficult to reach applications) plus miniature sizes (to be used in pencil grinders).
Features
Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but they are more brittle and has to provide with rigid tool holding systems
Uncoated tools feature only the base substrate without any additional treatment or coatings and so are suited to a variety of applications
Round shanks allow use which has a wide array of tool holding systems
Double-cut style has rows of cutting teeth decline in two intersecting directions for fast material removal as well as 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
It leaves a nice finish on many all materials, however the bite may 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 quantity of standard flutes in a opposing helix
Sliver sizing is greatly reduced, as is the operator fatigue from the balanced cutting forces
Lower RPMs may be utilized with little negative influence on performance
The decreased load compatible operator’s often feeding this tool more aggressively
Alumacut
Perfect for all non-ferrous, non-metallic workpieces like aluminum, zinc, plastic, wood, etc.
An extremely aggressive cutting action, with minimum possibility of plugging these flutes up
Diamondcut
Is really a finer cut of opposing helixes
Operating control is very good because the biting action is limited as is the silver size produced from it
This version is usually preferred in stores where titanium and also other difficult materials (superalloys) are increasingly being deburred
Together with the teeth being smaller and slightly more fragile because of this, tool life’s not commonly a matter of import
Fiberglass will cut nicely with Diamondcut
Chipbreaker
Another form of the Doublecut, this is a slightly less aggressive tool whose main purpose is to simply interupt the cut
One single, opposing helix is ground inside a spiral throughout the tool, typically
Silver size falls, surface finish falls marginally, hand control rises, marginally
