Collet-Chuck-Style Broach Tool Holders
The versatile collet-chuck-style broach toolholders use ER-style collets, which are said to reduce the time-consuming, three-screw method of centering a high speed steel broach in the broach toolholder. Also, an ER style collet can hold broaches with shanks of virtually any diameter within its range. For example, one holder can hold three different broach tools with varying shank diameters.

The ER-style collet will hold virtually any diameter shank broach tool in the holder within the range of the collet. A built-in stop screw allows the operator to adjust for different length broaches and to compensate for different lengths on re-sharpened broaches.

Cut-Off And Pulling Operation Performed By One Tool
The combination bar puller/cut-off tool for CNC from Somma Tool Company is built to reduce cycle times because there is no need to index between cut-off and pulling operations. A single screw adjustment allows the jaws to be set up and adjusted for the next job. One turn of the screw moves both jaws in or out exact
