ZCCCT QEHS32N Tungsten Carbide Grooving Blade 32mm Nominal Size Neutral Hand for Steel External Turning

The ZCCCT QEHS32N is a high‑performance carbide parting/grooving blade from ZCC Cutting Tools (ZCCCT, Zhuzhou Diamond) – China’s leading carbide tool manufacturer. Designed for external diameter parting and grooving, it features a rigid structure and reliable clamping for stable, high‑efficiency cutoff operations on CNC and conventional lathes.

• Model: QEHS32N (parting blade, 32mm nominal size, neutral hand)
• Brand: ZCCCT (Zhuzhou Diamond Cutting Tools, China)
• Material: Premium tungsten carbide for high hardness and wear resistance
• Application: External diameter parting (cutoff) and grooving of steel, alloy steel, and cast iron
• Rigid Construction: Enhanced blade rigidity minimizes vibration and deflection during heavy cuts
• Neutral Hand (N): Suitable for both left‑ and right‑hand machining
• Compatible Holders: Fits standard QEHS‑series tool blocks for secure screw clamping

• Carbon steels (Q235, 1045, S45C) – primary
• Alloy steels (4140, 42CrMo4, HRC < 45)
• Grey cast iron (HT200, HT250)
• Low‑strength stainless steels (light cutoff only)

• External bar cutoff / parting operations
• Straight and shoulder grooving
• Mass production of standard mechanical parts
• General‑purpose turning on CNC and manual lathes

Engineered for stable cutoff and grooving, the QEHS32N delivers consistent performance, long tool life, and excellent value. Its robust carbide substrate and ZCCCT’s precision manufacturing ensure reliable results in both low‑ and high‑volume production environments.
