Materials used for endmill

HSS - The majority of end milling cutters will be made from standard High Speed Steel

(M7).

obalt - !or tougher machining applications cobalt end mills will be re"uired. obalt is a

M#$ tool steel with an %& cobalt content. 't usually will re"uire a premium price. obalt end

mills allow for an increase in feed rates oer regular M7. t Melin* we offer our complete

line of tools in M#$ cobalt steel* but all are priced at M7 price leels.

arbide - This tool material combines increased stiffness with the ability to operate at higher

S!+M. arbide tools are best for shops operating newer milling machines that do not hae

much chatter as the material can be brittle. arbide end mills re"uire a significant premium

 price oer the cobalt end mills* but they can also be run at speeds $ ,$ faster than HSS end

mills. !or best results mount in a hydraulic type holder.

ll types of end mills must be handled with care. This is particularly important when storing

in the Tool rib. Tools should be stored in a tube protector or dipped in a protectie coating.

Tool life will be significantly shortened if the tool edge is damaged.

Special ote about oatings - The use of coatings will increase the surface hardness of the

tool. This will allow for greater tool life andor increased cutting speeds / feeds (between ,0

- $0&). Standard coatings aailable at Melin include Titanium itride (Ti)* Titanium

arbonitride (Ti)* and luminum Titanium itride (lTi). These coatings are allaailable at the same price* depending on the tool. 1ther coatings aailable includeTitanium

luminum itride (Til)* 2irconium itride (2r)* 3iamond* and 4lac5 16ide. More info

on coatings.
