COLLET CHUCK STYLE OFFSET INTERNAL ROTATING BROACH TOOL HOLDERS

Internal Rotating Broach Holder

• More versatile, just change the collet to accept any shank diameter broaching tool within the collet range. For example, you may want to purchase three common size collets, 0.315 (8mm), 0.472 (12mm), and 0.500 for the ER20 broach tool holder. This will allow you to use one holder for all shank sizes.

• Built in stop screw allows you to adjust for different length broaches or to compensate for lengths on re-sharpened broaches.

• Eliminates necessity of centering cutting tool to "spindle" of broaching holder. No screws to knock cutting tool off center.

• Use only exact size High Precision DIN6499 ER collets.
