Hertel 1002283 Wnmg 332-AS Turning Insert HC1250T Carbide

Product Description

The HERTEL 1002283 is a solid carbide turning insert designed for precision metal-cutting operations on CNC and manual lathes. It carries the WNMG 332-AS designation with manufacturer grade HC1250T, applied via CVD coating for elevated heat and wear resistance. The insert features an 80-degree trigon shape, a negative rake angle of 10 degrees, and a neutral cutting direction, making it well-suited for general-purpose external and internal turning. Cutting geometry includes a 3/8-inch inscribed circle, a 3/16-inch insert thickness, and a 1/32-inch corner radius. Maximum depth of cut is 0.1181 inches (3.00 mm). The G-style chip breaker supports consistent chip control across a range of feed rates. Professional machinists and tooling specialists install and index these inserts.

This insert is intended for turning applications where the primary workpiece material falls within ISO material group M, which covers stainless steel and similar austenitic alloys. The WNMG 332-AS geometry is appropriate for medium to finishing passes in both production and job-shop environments. The multi-tipped configuration provides multiple usable cutting edges per insert, reducing tooling cost per part. The insert is held in place using a clamp-and-pin method, which is standard for WNMG-style toolholders. Package quantity is one insert per package; minimum order quantity is 10 units.

Key Features

• WNMG 332-AS insert style with 80-degree trigon shape and neutral cutting direction
• HC1250T grade with CVD coating for wear resistance in stainless and difficult-to-cut materials
• Negative rake angle and G-style chip breaker for controlled chip evacuation
• 1/32-inch corner radius suitable for medium finishing passes
• Multi-tipped design delivers multiple cutting edges per insert
• Clamp and pin holding method compatible with standard WNMG toolholders

Compatibility

Designed for use in WNMG-style turning toolholders that accept a 3/8-inch inscribed circle insert with clamp-and-pin holding. ISO designation WNMG 060408-AS. Verify toolholder seat geometry and clamping system before installation.

Installation Notes

Installation and indexing of carbide turning inserts should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked. Use the correct torque wrench and manufacturer-specified clamping hardware for the toolholder to avoid seat damage or insert fracture. Inspect the toolholder pocket and seating surfaces for wear or debris before seating a new insert. Never overtighten the clamping screw, as this can cause insert cracking or premature edge failure.
