Sandvik Coromant 5745871 R390 Milling Insert 11mm Carbide

Product Description

The SANDVIK COROMANT 5745871 is a solid carbide milling insert designed for high-performance face and shoulder milling operations. Carrying the ANSI/ISO designation R390-11 T3 16E-KM H13A, this insert fits the R390 cutter series and is manufactured in the H13A uncoated grade. It measures 11.00 mm wide and 3.97 mm thick, with a 1.60 mm corner radius and a positive rake angle of 25 degrees. The KM chip breaker geometry promotes efficient chip evacuation during interrupted and continuous cuts. This insert is installed by machinists and tool-room technicians working on CNC milling centers and manual mills.

This insert is suited for single-sided, right-hand cutting applications across a range of workpiece materials including cast iron, non-ferrous metals, and superalloys and titanium. The uncoated H13A solid carbide substrate performs reliably in applications where coating adhesion or thermal sensitivity is a concern, making it a practical choice for machining aluminum alloys, copper-based materials, and high-temperature alloys. The maximum depth of cut is 10.00 mm, which supports both roughing and semi-finishing passes. Compatible with M-32 and R390 cutter series toolholders.

Key Features

• Solid carbide construction in uncoated H13A grade for cast iron, non-ferrous, and superalloy applications
• KM chip breaker geometry promotes controlled chip formation and evacuation
• Positive rake angle of 25 degrees reduces cutting forces on the workpiece
• 1.60 mm corner radius with corner-rounded cutting edge style for improved edge strength
• Maximum depth of cut of 10.00 mm supports roughing through semi-finishing
• Right-hand, single-sided insert secured by screw clamping for positive seating

Compatibility

Compatible with M-32 and R390 series milling cutters. ANSI code R390-11 T3 16E-KM H13A and ISO code R390-11 T3 16E-KM H13A. Insert size code 11T316.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder specification; do not over-torque the screw as carbide inserts are brittle and can fracture under lateral stress. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure proper contact and runout.
