Description

Utilizing left-hand helix geometry, these reamers avoid chip scratches on processed hole walls, specifically for demanding through-hole precision tasks.

Left-hand spiral pushes chips forward, designed for high-precision through-holes. Supports H7 tolerance.

This series combines spiral chip-pushing technology with the high rigidity of solid carbide. Within the 3-20mm range, they achieve H7 precision in carbon and alloy steels while delivering longer tool life and better surface consistency.
