PG-S Short Shank and PG-L Long Shank powRgrip collets

January 01, 2015

REGO-FIX has expanded its powRgrip product line with the introduction of PG-S short shank and PG-L long shank powRgrip collets. The additions facilitate customer use of shorterand longer-length carbide cutting tools.

To conserve carbide, many U.S. toolmakers are producing tools that are shorter than European/DIN equivalents. At the same time, some Asia-region and other customers prefer tools that are longer than European tools.

For the shorter tools, REGO-FIX now offers PG-S collets that have 3mm to 6mm shorter engagement than standard PG collets. PG-S collets permit customers to use off-the-shelf cutting tools instead of specials, and also provide more latitude for regrinding. PG-L collets accommodate longer tools by providing 3mm – 6mm longer engagement than standard collets. PG-S collets are available in PG 6, 10, 15, 25 and 32 sizes, while PG-L collets are available in PG 15, 25 and 32.

The REGO-FIX powRgrip system utilizes a special shallow-tapered collet that is pressed into a holder with a matching taper using either a hydraulic handpump or a tabletop hydraulic press. The system is engineered as an alternative to shrink fit and hydraulic toolholding systems and provides minimal runout, maximum clamping force, high vibration dampening and ease of use.
