Seco 02679241 Corner Chamfer End Mill 2mm 3 Flute Carbide

Product Description

The SECO 02679241 is a solid carbide corner chamfer end mill designed for precision material removal in demanding machining environments. Built on the JS553 series platform, it features a 2 mm mill diameter, 3 flutes, and a 48-degree high helix angle that promotes efficient chip evacuation during both roughing and finishing passes. The tool is coated with SIRON-A, a PVD AlCrN-class coating engineered to extend tool life when cutting ferrous and exotic materials. Centercutting geometry allows plunging and ramp-down entries without a pre-drilled pilot hole. This tool is intended for use by machinists and CNC operators working in precision milling applications.

This end mill is suited for a wide range of machining operations including shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging and recessing. The extended reach configuration and narrow 2 mm cutting diameter make it well-suited for tight-tolerance work in small-feature cavities. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. The short length-of-cut profile supports rigid setups with reduced vibration tendency.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material cutting
• SIRON-A PVD coating provides heat and oxidation resistance for extended tool life
• 48-degree high helix angle promotes efficient chip evacuation in slotting and shouldering
• Centercutting design supports plunging, ramp-down, and helical interpolation entry strategies
• 45-degree chamfer angle with 0.03 mm chamfer width for consistent edge preparation
• Right-hand cut and right-hand flute direction; compatible with standard CNC spindle rotation
• Normal pitch, no chipbreaker, no coolant-through — simplified setup for benchtop and production CNC use

Compatibility

Designed as a direct-use solid carbide corner chamfer end mill for CNC machining centers and manual mills accepting a 6 mm straight-cylindrical shank. Suitable for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces per ISO material groups P, M, K, N, and S.

Installation Notes

Installation and tool changes must be performed by qualified machinists with the spindle fully stopped and the machine in a locked-out state per applicable machine guarding and lockout-tagout procedures. Verify that the collet or tool holder bore matches the 6 mm shank diameter and that runout does not exceed the 0.01 mm TIR maximum before commencing cuts. Consult the machine tool builder and cutting tool documentation for appropriate feed and speed parameters based on workpiece material and depth of cut. Handle carbide tooling with care to avoid chipping the cutting edges during installation and storage.
