Description

The SECO 02468532 is a solid carbide milling insert carrying the ANSI/ISO designation SEMX1505AFTN-M18. It is a square-shaped, single-sided insert with a neutral hand orientation and a positive rake angle of 5 degrees. The insert features a TiAlN and TiN PVD coating over a fine-grain solid carbide substrate, providing wear resistance and thermal stability in demanding milling operations. With four cutting edges, a T-Land cutting edge style, and a 20-degree relief angle, this insert is engineered for productive face and shoulder milling in steel, cast iron, stainless steel, non-ferrous metals, superalloys, and titanium. It is sized at 5/8 inch inscribed circle with a thickness of 0.2189 inches and a corner radius of 0.0591 inches.

This insert is suited for use in CNC milling centers and machining centers across light manufacturing, aerospace, and general metalworking environments. It is compatible with the SECO R220.53-15 cutter series and is held in place by a screw-mount method. The M18 chip breaker geometry is optimized for medium-duty milling passes on steel and stainless steel as well as interrupted cuts in cast iron and superalloys. Installation is typically performed by machinists and CNC setup technicians in production or job-shop settings. The insert is sold individually but carries a minimum order quantity of 10 units.

Key Features

Solid carbide fine-grain substrate with TiAlN and TiN PVD dual coating for thermal and abrasion resistance
Four usable cutting edges per insert for extended tool life and lower per-edge cost
M18 chip breaker geometry suited for medium-duty milling of steel, stainless steel, cast iron, and superalloys
Positive rake angle of 5 degrees and T-Land edge style reduce cutting forces and protect the edge
Screw-mount insert holding method ensures secure, repeatable seating in compatible cutter bodies
Maximum depth of cut of 0.4055 inches with an effective cutting edge length of 0.6248 inches

Compatibility

Designed for use with the SECO R220.53-15 cutter series. ANSI and ISO code SEMX1505AFTN-M18 applies. Confirm cutter body pocket dimensions and screw specifications before installation.

Installation Notes

Insert replacement is performed by machinists or CNC tooling technicians with the machine powered off and the spindle locked. Use the appropriate torx or hex key as specified by the cutter body manufacturer to seat the clamping screw to the correct engagement without overtightening. Inspect the insert pocket for debris or damage before seating a new insert. Always verify insert orientation and confirm the cutting edge is properly engaged before resuming operation.
