The Hardinge Sure-Grip® Expanding Collet System is ideal for internal gripping of larger diameter bores. The Sure-Grip system has a larger gripping range and considerably more gripping force due to its true parallel closing. The #400 Series Expanding Collet will handle a range from 1-1/2" to 2.249" (38.1 to 57.12 mm). Collets are available in 1/64" increments within the above stated ranges. Each collet will hold a workpiece with a bore of -.001" (.0254 mm) under the size of the collet to +.015" (.38 mm) over the size of the collet.

Advantages of the Sure-Grip Expanding Collet System...
