Steel / carbide shank applications

Sign	Shank Type	Drawing
A	Steel Shank With Oil hole
C	Carbide Shank
S	Steel Shank
H	Alloy Tool Steel
-O	Alloy Steel shank With Oil Hole

Application range by shank type

Deep hole drilling of L/D = 6 with work diameters of 32mm and above.
Negative inserts reduce unit price per corner.
Combinable with a wide range of chipbreakers for use in everything from rough cutting to finishing.

Cutting Speed Vc=20~200m/min, Depth of cut ap=0.1~2.0mm, Feed Rate f=0.1~0.3mm/rev

*Actual amount of overhang may differ according to work material, tool shape, and machining conditions.
