Collet Chuck-Style Broach Toolholders
The new collet chuck-style broach toolholders are said to be versatile because they use ER-style collets, which are designed to reduce the three-screw method of centering the HSS broach in the broach toolholder. 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.
