Tool life
largely decided by the quality of the cutting
edge, which depends on the surface finish
of rake and clearance, face. Grinding with
high removal rates produces rougher face
and should be used for pregrinding operations
only. A properiy ground carbide face must
show neither heat discolorations nor grinding
marks. Tools for the machining of steel
(grades SB and EB will live considerably
longer it their cutting edges are dressed;
this is done manually with a diamond file,
or with a silicon carbide stone, if the
tools have been ground with a S;C wheel.
