Sandvik Coromant 5747874 Milling Insert Solid Carbide R790

Product Description

The SANDVIK COROMANT 5747874 is a solid carbide, uncoated milling insert designed for high-precision metal removal in milling applications. Carrying the H13A manufacturer grade, this parallelogram-shaped insert features a positive 9-degree rake angle and a corner-rounded cutting edge style that reduces cutting forces and promotes clean chip evacuation. It measures 16.00 mm wide and 5.00 mm thick, with a 0.80 mm corner radius. The insert seats via screw-lock clamping and is rated for a maximum depth of cut of 18.00 mm. It is intended for installation by machinists and CNC tooling technicians working with non-ferrous metals.

This insert is engineered for use in R790-series milling cutters and is primarily suited for machining non-ferrous metals, including aluminum and copper alloys. The bright, uncoated finish is well matched to applications where coatings may cause built-up edge or where sharp cutting geometry is critical to surface finish quality. The right-hand configuration suits standard R790 cutter bodies in both horizontal and vertical milling setups across light industrial and production environments. The single-sided design provides two cutting edges per insert, maximizing usable life before replacement.

Key Features

• Solid carbide construction in material grade K20, N15, and S20 for rigidity and wear resistance
• Uncoated bright finish optimized for non-ferrous metal machining
• Positive 9-degree rake angle with corner-rounded edge reduces cutting forces
• 0.80 mm corner radius for controlled surface finish at cut transitions
• Maximum depth of cut of 18.00 mm suits medium to heavy milling passes
• Screw-lock insert holding for repeatable, secure seating in the cutter body
• Two cutting edges per insert on a single-sided parallelogram form

Compatibility

Designed for use with R790-series milling cutter bodies. ANSI and ISO code: R790-220508PH-NM H13A. Insert size code 220508. Compatible with right-hand R790 cutter configurations.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to the cutter body manufacturer's recommended seating procedure when tightening the clamping screw — do not overtighten. Inspect the insert pocket for debris or damage before seating the new insert to ensure proper registration and runout.
