Sandvik Coromant 5854747 Milling Insert 490 Series Tialn

Product Description

The SANDVIK COROMANT 5854747 is a solid carbide milling insert designed for use in 490 series face and shoulder milling cutters. Coated with TiAlN via a PVD process, it delivers wear resistance and thermal stability in demanding cutting applications. The insert features a square shape with a 90-degree included angle, four cutting edges, and a positive 26-degree rake angle for reduced cutting forces. At 3.90 mm thick with an inscribed circle of 13.80 mm, it fits standard 490 series tooling. A 0.80 mm corner radius with a rounded cutting edge style helps manage chip load and extend tool life in production environments. Licensed trade machinists and CNC tool setters are the primary installers of this insert type.

This insert is sized to the 490R-140408M-PL 1020 ANSI and ISO code and is intended for milling cast iron workpieces in right-hand cutting configurations. The PL chip breaker geometry and positive rake are well suited to finish and semi-finish passes in cast iron applications where chip control and insert longevity are priorities. Typical install scenarios include horizontal and vertical machining centers running 490 series cutter bodies at speeds appropriate for grade 1020 solid carbide in K-class workpiece materials.

Key Features

• Solid carbide substrate with TiAlN PVD coating for thermal and abrasion resistance in cast iron
• Four usable cutting edges per insert maximizes cost-per-edge value
• Positive 26-degree rake angle reduces cutting forces and spindle load
• 0.80 mm corner radius with rounded cutting edge style for controlled chip formation
• PL chip breaker geometry optimized for cast iron finish and semi-finish milling
• Screw-held, single-sided insert with right-hand orientation for direct 490 series body compatibility

Compatibility

Designed for use with 490 series milling cutter bodies. ANSI and ISO designation 490R-140408M-PL 1020 confirms fitment. Insert size code 140408 applies. Compatible with right-hand cutter configurations in the 490 platform.

Installation Notes

Insert seating and screw torque should follow the cutter body manufacturer specifications for 490 series toolholders. Power down and lock out the spindle drive before changing inserts. Inspect the insert pocket seat for chips or debris before seating the new insert, as contamination can cause insert rocking and premature breakage. Handling solid carbide inserts with gloves or an insert tool is recommended to avoid edge damage and skin contact with metalworking coatings.
