Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal.
Cemented carbide is capable of cutting speed 3 to 4 times greater than HSS cutting tools.

Single point cutting tools contain only one main cutting edge in the cutter body. While machining with single point cutting tool, only one main cutting edge continuously remains in contact with work-piece.
Examples of single point cutters: Turning tool, Shaping tool, Planing tool, Slotting tool, Boring tool, Fly milling cutter, etc.
Multi point cutting tools contain more than one (even up to hundreds) cutting edges in the cutter body.
While machining with multi point cutting tool, more than one cutting edges simultaneously engage in material removal action in a pass.
Examples of multi-point cutters:, Milling cutters, Hobs, Broach, Grinding wheels, Reamer, Knurling tool, etc.

The width of a form tool should never exceed 3 times the smallest diameter of the finished part.
