Sandvik Coromant 5743992 Milling Insert Grade 3040 R245

Product Description

The SANDVIK COROMANT 5743992 is a solid carbide milling insert designed for use in R245 series face milling cutters. It carries ANSI and ISO designation R245-12 T3 M-KM 3040 and features a TiCN plus Al2O3 CVD coating applied over a grade 3040 carbide substrate. The square insert geometry provides four usable cutting edges, a positive 6-degree rake angle, and a 1.50 mm corner radius. Maximum depth of cut reaches 6.50 mm. The KM chip breaker geometry promotes controlled chip evacuation across a range of cutting conditions. This insert is held in place by a screw clamp and is right-hand oriented.

This insert is suited for milling steel, cast iron, and hard materials, covering ISO material application codes P, K, and H. It is appropriate for both roughing and semi-finishing passes where consistent chip control and wear resistance are required. The CVD coating process delivers a hard, thermally stable surface layer that extends tool life in moderate to high cutting speed applications. Machinists and CNC tooling technicians working in job shop, production, and maintenance environments will find this insert applicable to a broad range of workpiece materials.

Key Features

• Grade 3040 solid carbide with TiCN and Al2O3 CVD multilayer coating for extended tool life in steel and cast iron
• Square insert shape with 4 cutting edges maximizes cost-per-edge value
• Positive 6-degree rake angle reduces cutting forces and heat generation
• KM chip breaker promotes reliable chip control across varying feed rates
• Corner radius of 1.50 mm reduces edge chipping and improves surface finish at corners
• Maximum depth of cut of 6.50 mm supports both roughing and semi-finishing applications

Compatibility

Designed for use with R245 series milling cutter bodies. ANSI and ISO designation R245-12 T3 M-KM 3040 confirms fitment within compatible R245 cutter platforms accepting insert size code 12T3.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Disengage and lock out machine power before changing inserts. Use the correct Torx or hex key driver for the clamping screw and seat the insert fully against the pocket before torquing. Inspect the insert pocket for chips or debris prior to seating a new insert, as contamination in the pocket can affect seating accuracy and edge life.
