Somma Tool Co. offers a new style of broach toolholder designed to be interchangeable with any style of ER collet chuck. The compact, adjustment-free offset rotary toolholder threads onto an existing ER (16, 20, 25 and 32) collet chuck and features a built-in 1-degree wobble cutting edge for offset rotary broaching. This versatile broaching holder enables the user to swap one holder among different styles of shanks including round, Capto, VDI, Morse, CAT and NMTB taper. The holder reduces the need for toolholder adapter bushings, making it an economical alternative to other broaching systems, the company says.
These rotary broach holders use SommaSiwss broaches with 8-mm diameter shanks and ½" diameter shank broaches. The system is adjustment-free for on-center applications not requiring offset compensation.
