Seco 03060294 Corner Radius End Mill 6mm 6 Flute Carbide

Product Description

The SECO 03060294 is a solid carbide corner radius end mill engineered for high-performance milling in demanding materials. With a 6 mm cutting diameter and a 1 mm corner radius, it delivers controlled edge geometry that reduces chipping and extends tool life in difficult-to-machine alloys. The 6-flute design increases feed rates and improves surface finish compared to lower-flute-count tools. An HXT coating provides thermal resistance and lubricity, making it well suited for dry or semi-dry cutting conditions. The 17 mm length of cut and 57 mm overall length give machinists adequate reach for common pocket and profile operations without sacrificing rigidity.

This end mill is intended for roughing operations in stainless steel and high-temperature superalloys, material classes where tool wear and heat generation are primary concerns. Its centercutting geometry allows plunge entry, and the right-hand spiral flute direction suits standard CNC milling setups. The JS720 series is designed specifically for stainless steel and superalloy applications in production environments where consistent dimensional accuracy and tool life matter. Typical users include CNC machinists and tool crib technicians in aerospace, medical device, and industrial manufacturing shops.

Key Features

• 6 mm cutting diameter with 1 mm corner radius reduces stress concentration at the cutting edge
• 6 spiral flutes increase material removal rate and improve surface finish in tough alloys
• HXT coating enhances heat and wear resistance for stainless steel and superalloy cutting
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Submicron carbide grade provides a fine, uniform grain structure for edge toughness
• Straight-cylindrical shank with h5 tolerance ensures precise tool holder fit and minimal runout

Compatibility

Designed as an OEM-style solid carbide corner radius end mill in the SECO JS720 series, intended for use in standard CNC milling tool holders accepting a 6 mm straight-cylindrical shank. Primary workpiece materials are stainless steel and high-temperature superalloys.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician following the tool holder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the shank. Use a calibrated tool presetter to confirm overall length and runout before cutting. Verify that cutting parameters — feeds, speeds, and depth of cut — are set per the material and operation type, as improper parameters accelerate wear on carbide tooling.
