Sandvik Coromant 6289923 Milling Insert 2040 Solid Carbide

Product Description

The SANDVIK COROMANT 6289923 is a solid carbide milling insert designed for use in Series 419 milling cutters. It carries the manufacturer grade 2040 and features a multilayer CVD coating of TiCrN, Al2O3, and TiN, providing wear resistance and thermal protection during interrupted and continuous cuts. The insert has a pentagon shape with five cutting edges, a positive rake angle of 5 degrees, and a corner radius of 3.00 mm (0.1181 inches). Thickness measures 5.47 mm (0.2154 inches) and the inscribed circle diameter is 13.50 mm (0.5315 inches). A screw-held mounting method and SM chip breaker geometry are standard. Installed by machinists and tooling technicians in CNC milling operations.

This insert is suited for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. It is applicable to medium-to-roughing milling passes with a maximum depth of cut of 2.00 mm (0.0787 inches). The single-sided, neutral-hand design and corner-rounded cutting edge style make it appropriate for a range of face and shoulder milling applications in both production and job-shop environments. The 2040 grade is positioned within the P45, M40, and S30 material application ranges, targeting demanding cuts in difficult-to-machine alloys as well as general steel work.

Key Features

• Pentagon shape with 5 cutting edges for efficient edge utilization per insert
• CVD multilayer coating: TiCrN, Al2O3, TiN for thermal barrier and crater wear resistance
• Positive rake angle (5 degrees) reduces cutting forces on difficult materials
• SM chip breaker geometry designed for steel, stainless steel, superalloys, and titanium
• Corner radius of 3.00 mm contributes to surface finish and edge strength
• Screw-held mounting method for secure, repeatable seating in Series 419 toolholders

Compatibility

Designed for use with Series 419 milling cutter bodies. ANSI and ISO code: 419N-140530E-SM 2040. Insert size code 140530. Compatible cutter series: 419.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket locating surfaces before torquing the clamping screw; use the manufacturer-specified torque driver for Series 419 toolholders. Inspect the insert pocket for chips or damage before each insert change to ensure accurate seating and runout control.
