TT Style Carbide Inserts - Grade TNC |
|
|
TT Style Carbide Inserts: TNC coated grade C5/C6 carbide for cutting steel.
For indexable lathe turning tool holders.
Inserts have 7 degree positive rake and chipbreaker groove.
These are the only inserts that will work in our series "TTIM-" indexable turning tools.
These inserts will not work in toolholders that require inserts with an 11 degree positive rake (like some USA brand holders.)
The 3/8" shank holders use TT-221 or TT-222.
Other sizes use TT-321, TT-322, or TT-323.
Made in the USA.
The I.C. dimension is the diameter of a circle that could be drawn within a triangular insert, touching the midpoint of each side.
