Sandvik Coromant 5743980 Milling Insert H13A Solid Carbide

Product Description

The SANDVIK COROMANT 5743980 is a solid carbide milling insert designed for use in R245 series face and shoulder milling cutters. Grade H13A in an uncoated, bright finish, this insert carries a square shape with a positive rake angle of 6 degrees and a corner radius of 0.0591 inches (1.50 mm). Four cutting edges per insert maximize tool life before replacement. The KM chip breaker geometry promotes controlled chip evacuation across a range of workpiece materials. It is installed by licensed machinists and CNC tooling specialists in metalworking and precision machining environments.

This insert is suited for milling cast iron, non-ferrous metals, and superalloys including titanium. The H13A grade corresponds to ISO material grades K20, N15, and S20, covering applications from gray and ductile cast iron to aluminum alloys and titanium-based superalloys. Right-hand cutting orientation supports standard cutter configurations. Maximum depth of cut reaches 0.2559 inches (6.50 mm), making it appropriate for both roughing and semi-finishing passes in industrial machining operations.

Key Features

• Solid carbide H13A grade, uncoated bright finish for cast iron, non-ferrous, and superalloy applications
• Square insert shape with positive rake angle of 6 degrees for reduced cutting forces
• Corner radius of 0.0591 inches (1.50 mm) for corner-rounded cutting edge style
• Four cutting edges per insert for extended tool life per unit
• KM chip breaker geometry for controlled chip formation
• Screw-held mounting in standard R245 series toolholders

Compatibility

Designed for use with R245 series milling cutter bodies. ANSI and ISO code: R245-12 T3 M-KM H13A. Insert size code: 12T3. Compatible with right-hand R245 cutter configurations requiring a 12-size square insert.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the milling cutter is fully de-energized and spindle is locked before seating or replacing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer when tightening the insert clamping screw. Do not exceed the maximum depth of cut for the cutter body series being used.
