The first uniformly adjustable, positive rake, indexable insert hollow mill enables you to hollow mill from the end of the part with multiple indexable inserts.

Combines standard ISO inserts in precision, match ground, uniformly adjustable insert holders for hollow milling both ferrous and non-ferrous materials.

Tools have ¼” range of adjustability from .040″ to 2″ diameters.

A unique combination of toolholder geometry and insert geometry produces constant axial and radial rake and constant clearance angles through the entire range of diameter adjustment.

All tools have at least three, and, in larger sizes, as many as five inserts hollow milling for maximum productivity.

Tools are standard with straight shanks for use with toolholders in CNC machining centers, lathes and screw machines or in conventional turning, milling or automatic screw machines. All tool bodies are precision hardened and ground for years of dependable use. Special tools, shanks, toolholders quoted on application.



Genesee’s large selection of precision ground GEN-DEX® inserts provide the distinct advantage of the “C” tolerance on I.C. and thickness. This feature, normally available only by special order, contributes to optimum, balanced cutting of the hollow mill.
