Precision ER Straight Shank Collet Chuck & Extension for Professional Machining

High-grade hardened steel construction ensures durability and wear resistance under heavy-duty operations. Precision-ground M or A type taper guarantees seamless tool alignment for zero runout accuracy.

Engineered for CNC milling, lathe work, and high-speed drilling applications. Compatible with ER collets (ER11-ER40) for versatile tool clamping across metals, plastics, and composites.

Heat-treated alloy steel extension provides vibration damping during deep-hole boring. Mirror-polished inner surfaces prevent chip buildup for smooth collet release.

Direct-mount design fits standard machine tool spindles without adapters. Ideal for aerospace part machining, automotive prototyping, and precision mold making workshops.

Wholesale bulk pricing available for factory procurement. Globally shipped with OEM-quality assurance.
