Seco 02968290 Corner Radius End Mill 8mm 2-flute Carbide

Product Description

The SECO 02968290 is a solid carbide corner radius end mill designed for high-performance milling in steel and cast iron applications. With an 8 mm cutting diameter, 8 mm length of cut, and a 4 mm corner radius, this single-end tool delivers both roughing and finishing capability in one pass. The HXT coating extends tool life in demanding ferrous materials. Two right-hand spiral flutes with a medium helix angle promote efficient chip evacuation and stable cutting action. The tool features an extended-reach design with a 16 mm reach length and a reduced neck diameter of 7.40 mm, allowing access to deeper features without sacrificing rigidity.

This end mill is suited for CNC machining centers and milling operations on steel and cast iron workpieces, including both roughing passes and finish profiling. The centercutting geometry allows plunge entry, making it applicable to pocketing, contouring, and slotting operations. The straight-cylindrical shank with h5 tolerance ensures consistent tool holding in standard collet or end mill holders. It is part of the JH112 series, which is engineered for general-purpose precision milling in production environments.

Key Features

• Solid carbide submicron-grade construction for hardness and wear resistance
• HXT coating optimized for steel and cast iron cutting
• 4 mm corner radius reduces stress concentration and extends edge life
• Extended-reach design with 16 mm reach length and 7.40 mm neck diameter
• Centercutting geometry enables direct plunge entry
• Right-hand cut, right-hand flute spiral with medium helix for efficient chip flow

Compatibility

Designed for use on steel and cast iron workpieces (ISO material codes P and K). Fits standard straight-bore collet chucks, shrink-fit holders, and end mill holders accepting an 8 mm shank diameter. Part of the SECO JH112 series.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's runout and tool projection specifications. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tools. Verify shank seating depth and holder clamping torque per the tool holder manufacturer's guidelines. Do not exceed the manufacturer's recommended cutting parameters for the workpiece material grade.
