Tungaloy 6741710 VNMG332HRF AH8015 Turning Insert

Product Description

The TUNGALOY 6741710 is a VNMG332HRF-series indexable turning insert in grade AH8015, manufactured from solid carbide with a PVD-applied TiAlN coating. The insert features a 35-degree diamond (V) shape with a neutral hand orientation and a 0 degree relief angle (N clearance). With 4 cutting edges, a honed cutting edge style, and the HRF chip breaker geometry, it is suited for productive turning, facing, boring, back turning, and back boring operations. Licensed machinists and CNC lathe operators use this insert in toolholders designed for VNMG-style clamped and pin-lock seating.

This insert is rated for use on a broad range of primary workpiece materials including steel (P), stainless steel (M), cast iron (K), non-ferrous metals (N), superalloys and titanium (S), and hard materials (H), corresponding to ISO material grades M10, M20, S10, and S20. Its AH8015 PVD grade is designed to maintain edge integrity at elevated cutting temperatures, making it a practical choice for both roughing and semi-finishing passes on demanding materials in production turning environments.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket before engaging the clamp and pin; an improperly seated insert can fracture under cutting load. Follow the toolholder manufacturer torque recommendations for the clamping screw - do not overtighten.
