ER32 Square and Hex Collet Block Set | 0.005mm High Accuracy Carbon Steel Workholding Holder, for CNC Lathe Engraving Milling Machine (ER32)

Kraciva ER32 square and hex collet block is a professional upgraded workholding fixture, specially designed for ER32 series collet clamping and multi-angle machining operations.Made of high-quality 45# carbon steel and processed by overall quenching hardening, the whole tool block features high structural density, strong toughness and outstanding wear resistance. After multiple fine precision grinding procedures, the clamping surface is smooth and flat, ensuring tight fitting with ER32 collets without gap and slipping.This ER32 collet block maintains ultra-tight industrial tolerance with total accuracy within 0.005mm. Stable clamping performance can effectively offset machining vibration, ensure consistent dimensional tolerance of batch workpieces, and lower defective rate in long-term production.It can complete cross drilling, lateral cutting, special-shaped parts processing and tool clamping tasks. Dual square and hexagonal design greatly expands the processing range, suitable for round shank, square shank and hexagonal shank cutting tools.Widely applicable to CNC lathes, milling machines, engraving machines, bench drills and mechanical processing equipment. Solid thickened body improves pressure resistance and impact resistance, suitable for light and medium cutting, precision finishing, small mold making and mechanical parts processing. Easy to install and fix, it is an essential auxiliary tool for machinery workshop processing.
