Komet 1082251213 Indexable Drill Insert BK7935 Square Carbide

Product Description

The KOMET 1082251213 is a solid carbide indexable drill insert designed for use in KOMET BK7935 series indexable drilling systems. This square-style insert features an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in demanding holemaking operations. With a 1/2 inch inscribed circle, a 0.2031 inch thickness, and a 0.0315 inch corner radius, it is sized for precision fit and controlled chip formation. Installation is handled by machinists and tooling specialists working in CNC or manual drilling applications across metalworking environments.

This insert is suited for indexable drilling operations on steel, cast iron, and similar workpiece materials where AlTiN-coated carbide provides a performance advantage over uncoated or TiN-coated grades. Typical install scenarios include production drilling in machining centers and drill presses using compatible KOMET BK7935 indexable drill bodies. The insert is sold individually but carries a minimum order quantity of 10 units, making it appropriate for toolcrib stocking and production cell replenishment.

Key Features

• Solid carbide substrate for rigidity and wear resistance in holemaking applications
• AlTiN coating provides elevated heat resistance and extended cutting edge life
• Square insert geometry with 0.0315 inch corner radius for controlled chip flow
• 1/2 inch inscribed circle diameter ensures precise seating in BK7935-series drill bodies
• 0.2031 inch insert thickness for stable clamping and repeatable indexing

Compatibility

Designed for use with KOMET BK7935 series indexable drill bodies that accept a square solid carbide insert with a 1/2 inch inscribed circle.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician. Ensure the drill body pocket and clamping screw threads are clean and free of chips before seating the insert. Use the manufacturer-specified torx or hex key at the recommended seating torque for the insert clamping system - do not over-torque the clamp screw, as this can fracture the carbide. Power down and lock out the machine spindle before indexing or replacing inserts.
