BT ER Collet Chuck with M type Nut

BT ER spring collet chuck with M type nut, only the Nut is different with the normal BT ER collet chuck. The feature of M type nut is the small diameter that can prevent interference during operation. BT ER Spring Collet Chuck Milling Tool Holder, Mechanical spindle and cutting tools and other accessories. High Precision BT shank Tool Holder, balanced G6.3 or G2.5 For choose, With DIN6499 collet chuck can be straight shank cutter clamping various sizes. Due to the thread is different, the M type tool holder cannot change the nut to other type nut, like A type, UM type and GER type nut.

When ordering, please specify the form: A, AD Or (AD+B).

We are specializing in the production of BT ER Spring Collet Chuck, we can to figure to sample processing, and perfect after-sales service and technical support. Looking forward to your cooperation!
