Iscar 5567135 SOMT16HD IC808 Indexable Drill Insert

Product Description

The ISCAR 5567135 is a solid carbide indexable drill insert designed for use in indexable twist drills requiring a square SOMT-style insert. Manufactured under the IC808 grade with a PVD coating process, this insert features a 16 mm (0.6300 inches) inscribed circle, a 0.219-inch thickness, and a 1.19 mm corner radius. The HD chipbreaker geometry is optimized for controlled chip formation across a broad range of workpiece materials. Installation and replacement are performed by qualified machinists and tooling technicians during routine insert indexing or drill body maintenance.

This insert is suited for universal application across multiple material categories, including ISO material groups H, K, M, P, and S. It is part of the DR-TWIST series and is intended for use in compatible ISCAR DR-TWIST indexable drill bodies that accept SOMT 160512-style inserts. Typical applications include through-hole and blind-hole drilling operations in production machining environments across steel, stainless, cast iron, non-ferrous, and heat-resistant alloy workpieces.

Key Features

• IC808 grade with PVD coating for wear resistance across universal workpiece materials
• HD chipbreaker geometry for effective chip control in a wide range of drilling conditions
• Square SOMT insert style with 16 mm inscribed circle and 0.6300-inch width
• Fine grain carbide substrate for toughness and edge stability
• 1.19 mm corner radius reduces stress concentration at the cutting edge
• Compliant with ISO 13399 tooling data standards

Compatibility

Designed for use in ISCAR DR-TWIST series indexable drill bodies that accept SOMT 160512 square-style inserts with a 16 mm inscribed circle.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle powered off and the machine in a locked-out, tagged-out state. Use the correct torque screwdriver or insert clamp key specified for the drill body to avoid seat damage. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Do not force the insert into position; proper seating requires no gap between the insert and pocket walls.
