Seco 02505935 Milling Insert SPMX12T308-75 F40M Carbide

Product Description

The SECO 02505935 is a solid carbide milling insert carrying ANSI/ISO designation SPMX12T308-75 in manufacturer grade F40M. It is a square-shaped, single-sided insert with a positive rake geometry and a T-Land cutting edge style. The insert features a PVD-applied TiAlN and TiN dual coating over a fine-grain carbide substrate, producing a wear-resistant edge suited for interrupted and continuous cuts. With four usable cutting edges, a 0.5000-inch inscribed circle, a thickness of 0.1563 inches, and a 0.0315-inch corner radius, it is sized for moderate-depth milling operations. Machinists and tool-room professionals install this insert into compatible SECO cutter bodies to machine steel, cast iron, stainless steel, non-ferrous metals, superalloys, and titanium.

This insert is intended for use in milling applications across job-shop and production environments where a single insert geometry must cover a broad range of workpiece materials. Primary material compatibility includes steel (ISO code P), cast iron (K), and superalloys and titanium (S). Secondary material compatibility extends to cast iron (K) and non-ferrous metals (N). With a maximum depth of cut of 0.5000 inches and a cutting edge effective length of 0.5000 inches, the insert suits face milling, shoulder milling, and copy milling passes. It is held in place by a screw-lock method and operates in a neutral hand orientation.

Key Features

• Solid carbide fine-grain substrate with PVD TiAlN and TiN dual coating for extended edge life
• Square insert shape with 90-degree included angle and positive 14-degree rake angle
• T-Land cutting edge style reduces cutting forces and edge chipping on difficult materials
• Four cutting edges per insert maximize cost-per-edge value
• 11-degree relief angle and 0.0315-inch corner radius balance surface finish with chip clearance
• Chip breaker designation 75 optimized for steel, stainless steel, cast iron, non-ferrous, superalloys, and titanium
• Screw-lock mounting method provides secure, repeatable seating in the cutter pocket

Compatibility

Designed for use with SECO cutter series R215.49-3, R220.69, and R417.19-3. Conforms to ANSI and ISO standard designation SPMX12T308-75, insert size code 12T3, series SPMX-12.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked out before changing inserts. Seat the insert fully into the cutter pocket and torque the clamping screw to the tool body manufacturer specification. Inspect the pocket seat and screw threads for debris or damage before installing a new edge.
