BEYOND DSBNL2525M12 (25x25mm / 1.000" Shank) Left-Hand 75° Lead Angle CNC Lathe External Turning Tool Holder | 150mm Length Heavy Facing Chamfering SNMG1204 Indexable Toolholder uncoated-holder External reverse threading is notoriously

External reverse threading is notoriously prone to harmonic micro-vibrations because the pointed nose geometry of threading inserts creates concentrated tool pressure

this standard 20mm diameter shank tool holder body features an R-type length profile (200mm total length) optimized to minimize deflection harmonics under heavy torsional loads

use a CVD coated carbide grade

A: Use any standard ISO holder that accepts SCMT 09T3 size (like the SSDCN series)

The -S Chipbreaker is a specialized geometry designed for low cutting resistance
