Kennametal 1191811 Triangle Indexable Insert Cbt Chipbreaker

Product Description

The KENNAMETAL 1191811 is a triangle-shaped indexable insert with a CBT chipbreaker geometry, designed for turning and boring operations in metal cutting applications. It features a 3/8 inch inscribed circle and an effective chipbreaker width of 0.087 inches. This insert is used in indexable toolholders where controlled chip formation is required during continuous or interrupted cuts. Machinists and tool room technicians rely on this style of insert for medium-duty turning applications across a range of workpiece materials. The triangle geometry provides three usable cutting edges per insert.

This insert fits standard indexable toolholders sized for triangle inserts with a 3/8 inch inscribed circle. It is suited for CNC lathes, manual lathes, and boring bars in production machining and job shop environments. The CBT chipbreaker is intended for applications where chip control is critical, such as finishing and semi-finishing passes on ductile metals. This insert is sold individually and requires a minimum order quantity of 10 units.

Key Features

• Triangle insert geometry with three usable cutting edges per insert
• CBT chipbreaker for controlled chip formation in turning and boring operations
• 3/8 inch inscribed circle for compatibility with standard triangle indexable toolholders
• 0.087 inch effective chipbreaker width suited for finishing and semi-finishing passes
• Indexable design allows quick edge rotation without removing the toolholder from the machine

Compatibility

Designed for use in standard indexable toolholders accepting triangle inserts with a 3/8 inch inscribed circle. Confirm toolholder insert pocket specification before ordering.

Installation Notes

Installation is performed by machining professionals following standard indexable insert seating procedures. Ensure the toolholder pocket and clamping mechanism are clean and free of chips before seating the insert. Torque the clamping screw according to the toolholder manufacturer specification. Inspect the cutting edge and chipbreaker geometry before initiating a cut to confirm correct seating.
