Hello for all
A newbie's strange question of the day :
Can we choose between HSS cutters, end mills versus cutters or end mills
with carbide inserts
what are the advantages and disadvantages of each one?


In general:

HSS tools can be ground sharper that carbide inserts.
A properly ground HSS tool can produce a smoother finish than a
carbide insert.
Carbide inserts can remove more metal faster than HSS tools.
Carbide inserts tend to chip on interrupted cuts, HSS tools don't.
Carbide inserts wear better than HSS tools, espcially on hard or
abrasive metals.
