Sandvik Coromant 7564351 Milling Insert 4340 Grade Cvd

Product Description

The SANDVIK COROMANT 7564351 is a solid carbide milling insert in the 490 series, designed for face and shoulder milling operations in demanding metalworking environments. It carries a 4340 manufacturer grade and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life across a range of workpiece materials. The square insert geometry offers 4 cutting edges, a 90-degree included angle, and a positive 23-degree rake angle. The inscribed circle measures 13.80 mm and insert thickness is 3.90 mm. This insert is sold individually but requires a minimum order quantity of 10 units.

The 7564351 is suited for milling operations on steel, stainless steel, and cast iron, corresponding to ISO material application codes P, M, and K (P40, M40, K40 material grades). It is a right-hand insert with a PM chip breaker and a corner-rounded cutting edge style, making it well suited for general-purpose roughing and semi-finishing passes on CNC machining centers and manual milling machines in both production shop and job shop environments. The insert is compatible with the Sandvik Coromant 490 cutter series and is held in place via screw clamping.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for wear resistance across P, M, and K material groups
• 4 cutting edges on a single-sided square insert for cost efficiency per edge
• Positive 23-degree rake angle reduces cutting forces on the spindle and workpiece
• PM chip breaker geometry designed for steel and stainless steel chip control
• Corner radius of 0.80 mm (0.0315 inches) with corner-rounded cutting edge style
• Screw-held insert style ensures rigid, repeatable seating in the cutter body

Compatibility

Designed for use with the Sandvik Coromant 490 cutter series. ANSI and ISO code: 490R-140408M-PM 4340. Insert size code: 140408. Fits 490-series cutter bodies that accept screw-clamped square inserts with a 0.1614-inch hole diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key for the clamping screw and follow the cutter body manufacturer seating guidelines. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
