Sandvik Coromant 5744707 Milling Insert Grade 1025 Carbide

Product Description

The SANDVIK COROMANT 5744707 is a solid carbide milling insert in grade 1025, designed for use in indexable milling cutters operating across a broad range of workpiece materials. The insert carries a dual PVD coating of TiCN and TiN, which provides wear resistance and thermal stability during interrupted and continuous milling cuts. It measures 9.5 mm wide and 3.5 mm thick, with a maximum depth of cut of 4.60 mm. The rectangular insert shape, 90-degree included angle, and corner-rounded cutting edge style suit shoulder and slot milling applications. Insert holding is by screw clamp. This insert is installed by machinists and toolroom technicians on CNC and manual milling equipment.

The 5744707 is intended for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, N, S, and H. It is a single-sided, right-hand insert with a positive rake geometry and WL chip breaker configuration. The insert fits the R331.1A cutter series and is compatible with the N331.32 cutter series. It is cataloged under ANSI and ISO code R331.1A-04 35 15H-WL1025. Typical applications include shoulder milling, face milling, and profile milling on production machining centers and toolroom mills.

Key Features

• Solid carbide substrate with PVD-applied TiCN and TiN dual coating for extended tool life
• Grade 1025 — suited for steel, stainless steel, cast iron, non-ferrous, superalloys, titanium, and hard materials
• WL chip breaker geometry with positive rake for controlled chip evacuation and reduced cutting forces
• Corner-rounded cutting edge style with 1.52 mm corner radius minimizes edge chipping and vibration
• Maximum depth of cut 4.60 mm with two cutting edges per insert
• Screw-held single-sided insert for secure, repeatable seating in the cutter pocket

Compatibility

Designed for use in SANDVIK COROMANT R331.1A series cutter bodies with N331.32 cutter series compatibility. ANSI and ISO designation: R331.1A-04 35 15H-WL1025. Insert size code 043515.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Disengage machine power and confirm spindle lock before changing inserts. Use the correct Torx or hex key to the cutter body manufacturers specified torque — refer to the cutter body documentation, as over-tightening the clamping screw can fracture the insert or damage the pocket seat. Inspect the pocket seat and clamping screw for wear or debris before seating a new insert.
