Broaches

Somma Tool Co. announces the development of a broach toolholder that is reportedly uniquely interchangeable among any style of ER collet chuck. The compact, adjustment-free, offset, rotary broach toolholder will thread to an existing ER (16, 20, 25 and 32) collet chuck and features a built-in 1-degree wobble cutting edge for offset rotary broaching.

Slater Tools’ new indexable punch broach toolholder facilitates punch or index broaching on a CNC lathe or mill. When rotary broaching is not an option due to the need to remove full form, excessive material and/or depth, static punch broaching is the preferred method of CNC broaching.
