Kennametal 1016512 Cbt Chipbreaker Indexable Insert

Product Description

The KENNAMETAL 1016512 is a triangular indexable insert featuring the CBT chipbreaker geometry, designed for use in indexable toolholders across turning and boring applications. The insert has a 0.5-inch inscribed circle (IC) and a 0.13-inch effective chipbreaker width. These CBT-style inserts are engineered to control chip flow and reduce cutting forces during metal removal operations. Licensed machinists, toolroom operators, and CNC programmers specify this insert geometry for general-purpose turning on steel and similar workpiece materials. Each package contains one insert, with a minimum order quantity of 10 units.

This insert is suited for production turning, facing, and light profiling operations where controlled chip formation is required. The triangular shape provides multiple cutting edges per insert, making it a cost-effective choice for high-volume machining environments. Typical applications include OD turning on lathes and turning centers in job shops and manufacturing facilities handling ferrous and similar materials.

Key Features

• CBT chipbreaker geometry for controlled chip evacuation during turning
• Triangular insert shape provides multiple usable cutting edges per insert
• 0.5-inch inscribed circle for compatibility with standard triangular insert pockets
• 0.13-inch effective chipbreaker width suited for general-purpose turning passes
• Sold individually per package with a minimum order quantity of 10 units

Compatibility

Designed as an OEM-style replacement or standard supply insert for indexable toolholders accepting triangular inserts with a 0.5-inch inscribed circle. Confirm seat geometry and clamping style against your specific toolholder specifications before ordering.

Installation Notes

Indexable insert installation should be performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified clamp screw procedure - do not over-tighten the clamp screw, as this can fracture the insert. Inspect the insert seat and shim for wear or debris before seating a new insert.
