Sandvik Coromant 5854762 Milling Insert 490R-140408E-ML 2040

Product Description

The SANDVIK COROMANT 5854762 is a solid carbide milling insert in the 490 series, designed for high-performance shoulder milling and face milling operations. It carries ANSI and ISO designation 490R-140408E-ML 2040 and is manufactured in grade 2040 with a CVD-applied multilayer coating of TiCrN, Al2O3, and TiN. The square insert geometry features a 90-degree included angle, a positive rake angle of 26 degrees, a 16-degree relief angle, and a corner radius of 0.80 mm (0.0315 inches). With four usable cutting edges and a maximum depth of cut of 10.00 mm (0.3937 inches), this insert delivers consistent performance across a range of ferrous and exotic workpiece materials.

This insert is intended for use in 490-series cutter bodies and is suited for machining steel, stainless steel, superalloys, and titanium — corresponding to ISO material grades P45, M40, and S30. Typical applications include shoulder milling, pocket milling, and ramping operations in aerospace, energy, and general machining environments. The ML chip breaker geometry is optimized for medium-light cutting conditions and helps manage chip formation when working with difficult-to-machine alloys. Licensed machinists and CNC technicians are the primary installers of this insert type.

Key Features

• Solid carbide substrate with CVD multilayer TiCrN, Al2O3, and TiN coating for wear resistance in high-heat cuts
• Four cutting edges on a single-sided, right-hand square insert maximizes cost-per-edge value
• ML chip breaker geometry suited for medium-light feeds on stainless steel, superalloys, and titanium
• Positive rake (26 degrees) and 16-degree relief angle reduce cutting forces and minimize built-up edge
• Maximum depth of cut of 10.00 mm (0.3937 inches) with a 0.80 mm corner radius for controlled edge entry
• Screw-lock insert holding method ensures repeatable seating in 490-series toolholders

Compatibility

Designed for use with 490-series cutter bodies. ANSI and ISO code 490R-140408E-ML 2040 confirms fitment in any 490-series holder accepting a 14 mm inscribed circle square insert with a screw-lock retention method.

Installation Notes

Insert replacement is performed by CNC machinists or toolroom technicians. Before changing inserts, power down the spindle and engage the machine lock-out per facility safety procedures. Use the appropriate Torx or hex key specified by the cutter body manufacturer to seat the clamping screw — do not overtighten, as carbide inserts are brittle and will crack under excess clamp force. Inspect the pocket seat and screw threads for chips or debris before installing a new insert.
