Seco 02923701 RPHT1204M0T-6-M08 Round Milling Insert F40M

Product Description

The SECO 02923701 is a solid carbide round milling insert carrying ANSI/ISO designation RPHT1204M0T-6-M08 and manufacturer grade F40M. Fine-grain solid carbide substrate is coated with a dual-layer TiAlN and TiN finish applied via PVD process, delivering thermal resistance and edge retention during high-speed milling operations. The insert features a positive rake angle of 16 degrees, an 11-degree relief angle, and a T-Land cutting edge style. Six usable cutting edges are available on this single-sided, neutral-hand insert. Inscribed circle diameter measures 0.4724 inches (12 millimeters) and thickness is 0.1874 inches. The M08 chip breaker geometry is optimized for moderate feed milling across a range of metallic workpiece materials.

This insert is suited for milling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits within insert size code 1204 of the RPHT-12 series and is designed for use in cutter bodies requiring a round, screw-held insert at this diameter. Typical install scenarios include face milling, shoulder milling, and copy milling in both production shop and field-maintenance contexts. The maximum depth of cut reaches 0.2362 inches, making it practical for moderate stock removal passes. The insert is held in place by a screw-type clamping method.

Key Features

• Solid carbide substrate with fine-grain material grade for rigidity and wear resistance
• Dual PVD coating: TiAlN plus TiN for elevated temperature and abrasion resistance
• 6 cutting edges per insert, single-sided neutral hand
• Positive rake (16 degrees) with T-Land edge style for reduced cutting forces
• M08 chip breaker geometry suited to moderate-feed milling of steel, cast iron, and superalloys
• Compatible with RPHT-12 series cutter bodies including R217.29-06 and R220.29-06

Compatibility

Confirmed compatible with Seco cutter series R217.29-06 and R220.29-06. Insert conforms to ISO standard RPHT1204M0T-6-M08 designation and fits any cutter body specifying RPHT-12 series round inserts with a 0.1772-inch hole diameter and screw clamping.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using the appropriate Torx or hex key for the insert clamping screw specified by the cutter body manufacturer. Ensure the machine spindle is fully stopped and locked out before seating or indexing inserts. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper contact and runout. Follow the cutter body manufacturer torque specification for the clamping screw — do not estimate torque by feel.
