Sandvik Coromant 5737264 Milling Insert Grade 1020 Carbide

Product Description

The SANDVIK COROMANT 5737264 is a solid carbide milling insert designed for precision face and shoulder milling operations in metalworking applications. Manufactured to the N331.1A series specification, this insert carries a Grade 1020 designation and features a TiAlN coating applied via PVD process. The rectangular insert shape measures 9.5 mm wide and 4.45 mm thick, with a 0.80 mm corner radius and a maximum depth of cut of 7.70 mm. Four cutting edges are available per insert, and the neutral hand orientation makes it compatible with a range of milling configurations. The chip breaker style is KM, suited for positive rake cutting setups targeting cast iron workpiece materials.

This insert is intended for use in industrial milling operations where cast iron is the primary workpiece material, corresponding to material grade K05 and ISO/ANSI material code K. The N331.1A-08 45 08E-KM1020 catalog designation identifies this insert within structured tooling systems. Typical installation scenarios include production milling of gray cast iron, nodular cast iron, and hardened cast iron components in both horizontal and vertical machining centers. The screw-holding method provides secure clamping during interrupted and continuous cut operations. This insert is used by machinists, toolroom technicians, and CNC setup operators working in precision machining environments.

Key Features

• Grade 1020 solid carbide construction with TiAlN PVD coating for extended tool life in cast iron applications
• 4 usable cutting edges per insert, maximizing cost efficiency per insert
• 0.80 mm corner radius reduces edge chipping during interrupted cuts
• Maximum depth of cut of 7.70 mm supports productive material removal rates
• Positive rake geometry with KM chip breaker reduces cutting forces in cast iron
• Screw-mount holding method provides rigid, repeatable seating in the cutter body
• Conforms to ANSI and ISO standards; ANSI/ISO code N331.1A-08 45 08E-KM1020

Compatibility

Compatible with the L331.52C cutter series as specified by the manufacturer. Designed for use in N331.1A series milling cutter bodies accepting insert size code 084508 with screw-type clamping. Verify cutter body insert pocket specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician with the spindle fully powered down and the machine in a locked-out state per applicable safety procedures. Use the appropriate torx or hex key driver as specified by the cutter body manufacturer when seating the clamping screw — do not overtighten. Inspect the insert pocket seating surface for chips or debris before installing a new insert. Replace all inserts at the same time when possible to maintain consistent cutting geometry across the cutter body.
