Tungaloy 6864674 Pcbn Turning Insert Triangle BXM10

Product Description

The TUNGALOY 6864674 is a triangular Polycrystalline Cubic Boron Nitride (PCBN) turning insert in the BXM10 grade, designed for high-performance machining of hard materials. Manufactured to ANSI and ISO standards, it carries a TiCN coating applied via PVD process, which improves wear resistance and extends cutting life on hardened steels and other difficult workpiece materials. With a 0.25-inch inscribed circle, a 0.0157-inch corner radius, and a positive rake geometry with honed cutting edges, this insert is suited for precision turning, facing, and boring operations. It is installed via screw-holding method and features a flat-top chip breaker with no wiper edge.

This insert is intended for turning, facing, and boring applications on hard materials, classified under ISO workpiece material code H. The triangular shape provides three cutting edges per insert, making it a multi-tipped, multi-use tool suitable for a range of lathe and boring operations in industrial machining environments. It is typically used by machinists and tooling specialists working on hardened components where carbide tooling has reached its performance limits. The ISO code for this insert is 3QP-TPGW110204 BXM10 and the industry standard number is 3QP-TPGW 21.51.

Key Features

• PCBN insert material with TiCN PVD coating for extended tool life on hard materials
• BXM10 manufacturer grade engineered for ISO H workpiece material classification
• Triangular insert shape with 60-degree included angle provides 3 usable cutting edges
• Positive rake angle with honed cutting edge style reduces cutting forces
• Screw-holding method with clearance code P and tolerance code G for precise, repeatable seating
• Suitable for turning, facing, and boring in a single insert geometry

Compatibility

Designed as an OEM-style replacement or direct-fit insert for tool holders accepting TPGW-style triangular inserts with a 0.25-inch inscribed circle and screw-holding method, conforming to ANSI and ISO insert standards.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using the specified screw-holding clamp system on compatible TPGW-style insert tool holders. Always power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and seating surfaces for debris or damage before securing the insert. Handle PCBN inserts with care, as the cutting edges are brittle and susceptible to chipping from improper seating or impact.
