Kennametal 2270901 Round Milling Insert RCGT250900SHF KCPK30

Product Description

The KENNAMETAL 2270901 is a solid carbide round milling insert carrying ISO designation RCGT250900SHF and ANSI code RCGT86SHF. Manufactured to grade KCPK30, it features a CVD-applied multilayer coating of TiN, TiCN, and Al2O3 for thermal resistance and wear protection across a broad range of cutting operations. The round insert geometry provides a 360-degree included angle with 4 available cutting edges, a positive rake angle of 25 degrees, and a 7-degree relief angle. At 1 inch inscribed circle diameter and 0.3748 inches thick, this insert is sized for medium-to-heavy milling applications. Installation is via screw-holding method, and the HF chip breaker designation indicates suitability for finishing passes. Licensed KENNAMETAL KSRM cutter series compatibility is confirmed.

This insert is engineered for milling steel, stainless steel, cast iron, superalloys, and titanium, covering material grades C1, C5, and C6 (ISO P, M, K, and S classifications). The neutral hand orientation and chamfered-plus-honed cutting edge style make it appropriate for a wide range of milling setups in both production and job-shop environments. Typical applications include face milling and profile milling on ferrous and exotic-alloy workpieces where consistent surface finish and tool life are priorities. The round insert form distributes cutting forces evenly, which reduces chipping risk on difficult-to-machine materials such as superalloys and titanium.

Key Features

• CVD multilayer coating: TiN, TiCN, and Al2O3 for high heat and wear resistance
• Round insert shape with 360-degree included angle and 4 usable cutting edges
• Positive 25-degree rake angle with 7-degree relief for reduced cutting forces
• HF chip breaker geometry optimized for finishing operations
• Compatible with KENNAMETAL KSRM cutter series
• Screw-holding method for secure, repeatable seating in the toolholder pocket
• Covers ISO P, M, K, and S workpiece material classifications

Compatibility

Confirmed compatible with the KENNAMETAL KSRM cutter series. Conforms to ANSI and ISO insert standards (ANSI code RCGT86SHF, ISO code RCGT250900SHF). Designed as a direct-fit replacement for any toolholder pocket specifying an RCGT series round insert with a 1-inch inscribed circle diameter and screw-holding retention.

Installation Notes

This insert is installed and serviced by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or changing inserts. Use the manufacturer-specified torx or hex key to drive the clamping screw; do not overtighten or use impact tools on insert-retention screws. Inspect the toolholder pocket seat for debris or damage before installing a new insert to ensure proper seating and runout.
