Sandvik Coromant 5888547 R390 Milling Insert 1040 Tialn

Product Description

The SANDVIK COROMANT 5888547 is a solid carbide milling insert designed for shoulder and face milling operations using R390-series cutter bodies. Manufactured to ANSI and ISO standard R390-17 04 12E-MM 1040, this parallelogram-shaped, single-sided insert carries a 1040 manufacturer grade with a PVD-applied TiAlN coating for heat and wear resistance. It features a positive rake angle of 22 degrees, two cutting edges, and a corner-rounded cutting edge style with a 1.20 mm corner radius. The insert is held in place by screw clamping and is suited for use by CNC machinists and tool-and-die professionals working in production milling environments.

This insert is intended for milling steel and stainless steel workpieces, corresponding to ISO material groups P and M. The MM chip breaker geometry supports a maximum depth of cut of 15.70 mm. Typical applications include shoulder milling and face milling in general machining and precision manufacturing settings, both in job-shop and production environments. Right-hand cutting orientation must be matched to the appropriate R390-series cutter body and spindle rotation before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before seating or removing inserts. Use the appropriate Torx or hex key for the insert clamping screw and follow the toolholder manufacturer seating procedure. Inspect the insert pocket and clamping surfaces for chips or debris before installing a new insert to ensure proper seating and runout.
