Helical Flute Thread Mills – Solid Carbide Surface Treated, TiAlN Coated

Features and Benefits

For high temperature and/or abrasive conditions
Use in stainless steel, high alloy carbon steels, nickel-based high-temp alloys and titanium. Not for use in aluminum.
Requires an increase of 75% to 100% in machine speeds
Eliminates secondary threading operations
Helical design produces superior finish and thread quality
Full thread forms to within one pitch of a shoulder
Cuts right or left-hand threads
Cuts large diameter threads with low horsepower machines
Solid micrograin carbide
Shank tolerances: +.0000 – .0005″
Metric shank tolerances: +.000 – .013mm

Surface Treatment: TiAlN (Titanium Aluminum Nitride)
