Seco 02923700 RPHT1204M0T-6-ME07 Round Milling Insert MS2050

Product Description

The SECO 02923700 is a solid carbide round milling insert carrying ANSI and ISO designation RPHT1204M0T-6-ME07, manufactured to SECO grade MS2050. The insert features a PVD-applied TiAlN and NbN dual coating and a micrograin carbide substrate, giving it wear resistance and toughness in demanding milling operations. The round RPHT geometry provides a 12 mm inscribed circle, a 0.1874-inch thickness, and six cutting edges per insert. The positive rake angle of 20 degrees and the T-Land cutting edge style reduce cutting forces while the ME07 chip breaker geometry controls chip flow. This insert is used by machinists and tooling technicians in CNC milling applications where insert performance and edge life are critical.

This insert is designed primarily for milling superalloys and titanium, classified under primary workpiece material code S. It also performs in steel and stainless steel applications, material codes P and M respectively. The neutral hand orientation makes it adaptable across setups. Typical install scenarios include face milling, shoulder milling, and contour milling on CNC machining centers where consistent chip breaking and positive rake geometry are needed for difficult-to-machine materials. The ME07 chip breaker geometry is specifically matched to light-to-medium depth cuts in these material groups.

Key Features

• Round RPHT insert shape with 6 cutting edges for extended tool life per insert
• PVD-coated TiAlN and NbN dual-layer coating for high heat and wear resistance
• Micrograin solid carbide substrate, MS2050 grade, optimized for superalloys and titanium
• Positive 20-degree rake angle with T-Land cutting edge style to reduce cutting forces
• ME07 chip breaker for controlled chip evacuation in steel, stainless steel, and superalloy cuts
• Maximum depth of cut of 0.2362 inches matched to the corner radius and cutting edge effective length

Compatibility

Compatible with SECO cutter series R217.29-06 and R220.29-06 as stated by the manufacturer. Insert is screw-held and conforms to ISO standard geometry RPHT1204M0T-6-ME07 within the RPHT-12 series. Minimum order quantity is 10 inserts; package quantity is 1.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the milling cutter body is fully de-energized and the spindle is locked before seating or changing inserts. Use the correct torx or hex key specified by the cutter body manufacturer to achieve proper clamping torque on the insert screw — do not over-torque. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure full contact and proper seating depth.
