REGO-FIX ER 20 5.0 mm Collet - 0.0004" TIR | BlackHawk Industrial Supply

Rego-Fix AG achieved international recognition in 1972 with the invention of the ER clamping system, made in Switzerland, is an industrial standard clamping element. It set the industry standard and even became DID standard (DIN 6499) in 1993. Today, the ER collet made by REGO-FIX is still the most used clamping collet worldwide. REGO-FIX manufactures its products in Switzerland to fit highest quality standards. The products are used in the fields of automotive, aerospace, medical, engineering, watchmaking, telecommunications and in the die and mold industry. NOTE: Never clamp oversized tool shanks. For example, never use a 12mm collet to clamp a 12.2mm shank. Rather, use the next bigger collet. Insert tool to the full length of the collet for best results. Also, never insert the tool less than 2/3 of the collet length. Improper tool insertion can permanently deform the collet and will result in poor runout. Improper assembly can permanently damage the runout TIR of the collet and may result in the destruction of the clamping nut. Only mount clamping nuts with correctly assembled collets.
