Description
High-Precision C25-ER20 x 100L Cylindrical Shank Baby Collet Chuck Holder (Slotted Nut)
The MTM C25-ER20-100L cylindrical shank baby collet chuck holder delivers high clamping rigidity and versatile capacity for CNC milling centers and lathe tool posts. Fitted with an ER20 slotted nut, it handles cutters up to 13mm shank diameter with runout accuracy ≤ 0.005mm.
Key Features & Benefits
- Versatile Clamping Range: Clamps tooling shanks from 1.0mm up to 13.0mm using standard ER20 collets.
- High-Speed Dynamic Balancing: Pre-balanced up to 15,000 RPM for vibration suppression and extended cutter life.
- Rigid 25mm Cylindrical Shank: Minimizes deflection during aggressive feeds and side-milling cuts.
- Sub-Micron Grinding Accuracy: Precision ground shank and taper with runout accuracy ≤ 0.005mm.
