Seco 03280741 Round Milling Insert MP2501 8-edge Carbide

Product Description

The SECO 03280741 is a round milling insert in the RDKW-10 series, designed for face milling and shoulder milling operations on CNC machining centers. It is manufactured from fine-grain solid carbide and carries a CVD-applied Duratomic multilayer coating of TiCN and Al2O3, which improves wear resistance and edge stability during interrupted and continuous cuts. The insert has 8 usable cutting edges, an inscribed circle of 0.3937 inches (10.00 mm), a thickness of 0.1563 inches (5/32 inch), and a corner radius of 0.1969 inches (5.00 mm). The neutral rake geometry and T-Land cutting edge style make it suitable for a range of steel and steel-adjacent workpiece materials. It is held in the cutter body by a screw-clamp method.

This insert is intended for use in industrial and production machining environments. It is the correct grade selection for primary cutting of steel (ISO P materials), with secondary suitability for stainless steel, cast iron, and superalloys and titanium (ISO M, K, and S material codes). The MD06 chip breaker geometry is suited to medium-depth roughing and semi-finishing passes. Maximum depth of cut is 0.1969 inches. The cutter series compatibility listed in the manufacturer data is R217.29-05 and R220.29-05. Installation and indexing are performed by machining technicians and CNC setup personnel.

Key Features

• Fine-grain solid carbide substrate with CVD Duratomic TiCN and Al2O3 multilayer coating for extended tool life
• Round insert shape with 360-degree included angle provides 8 indexable cutting edges per insert
• Neutral rake angle with T-Land cutting edge style for stable engagement in steel and interrupted cuts
• MD06 chip breaker geometry suited to medium roughing and semi-finishing applications
• Screw-held single-sided insert; compatible with R217.29-05 and R220.29-05 cutter bodies
• ISO and ANSI coded as RDKW10T3M0T-8-MD06 for standardized tooling selection

Compatibility

Compatible with SECO cutter series R217.29-05 and R220.29-05 as specified by the manufacturer. Intended for machining steel as the primary workpiece material, with secondary application in stainless steel, cast iron, and superalloys and titanium.

Installation Notes

Insert indexing and replacement should be performed by a qualified machining technician with the machine spindle stopped and all motion axes locked out per facility lockout/tagout procedures. Use the appropriate torque wrench or hex key specified by the cutter body manufacturer when securing the clamping screw; do not overtighten. Inspect the cutter pocket seating surface and screw threads for debris or damage before seating the new insert. Verify runout and depth-of-cut settings before resuming production cuts.
