Hertel 1001147 VNMG332R HC335 Carbide Turning Insert

Product Description

The HERTEL 1001147 is a VNMG332R-style indexable turning insert manufactured from solid carbide and coated with TiC, TiCN, and TiN via a CVD process. Grade HC335 provides a balanced combination of wear resistance and toughness suited to general turning operations. The insert measures 0.654 inches in length with a 3/8 inch inscribed circle, a 3/16 inch thickness, and a 1/32 inch corner radius. The neutral hand orientation and G-style chip breaker geometry make this insert a practical choice for machinists running steel and stainless steel turning applications on CNC lathes and turning centers.

This insert is designed for use in external and internal turning operations where consistent chip control and surface finish are priorities. The diamond 35-degree included angle (V shape) allows access to complex workpiece profiles with minimal interference. Primary workpiece material code P indicates suitability for steel, while secondary code M covers stainless steel and similar materials. Material grades C5 and C6 position this insert for medium to finishing cuts. It is held in the toolholder using clamp and pin methods, consistent with standard VNMG toolholder configurations used in production and job-shop environments.

Key Features

• CVD multilayer coating: TiC, TiCN, and TiN for enhanced wear resistance and heat control
• HC335 carbide grade suited for steel and stainless steel turning
• G-style chip breaker geometry for reliable chip evacuation during medium to finishing cuts
• Neutral hand insert fits both left-hand and right-hand VNMG toolholders
• Clamp and pin holding method for secure, repeatable seating in compatible toolholders
• 1/32 inch corner radius balances workpiece surface finish with cutting edge strength

Compatibility

Designed as an OEM-style replacement or standard stocking insert for VNMG332 toolholders accepting clamp and pin retention with a 0.150 inch hole diameter.

Installation Notes

This insert is installed and serviced by machinists and tooling technicians on CNC lathes and manual turning centers. Power down and lock out the spindle before indexing or replacing inserts. Use a torque wrench appropriate for the toolholder manufacturer's specified clamp screw to avoid cracking the insert or stripping the clamp. Inspect the insert seat and chip pocket for debris before seating the new insert to ensure proper contact and runout.
