Seco 02970110 Corner Radius End Mill 4mm 4-flute Carbide

Product Description

The SECO 02970110 is a solid carbide corner radius end mill designed for precision milling of steel and cast iron. It features a 4 mm cutting diameter, a 4 mm length of cut, and a 0.3 mm corner radius that reduces stress concentration at cutting edges and extends tool life in demanding applications. The 4-flute, right-hand spiral design with a medium helix angle supports both roughing and finishing operations in a single tool. An HXT coating provides thermal and wear resistance for high-performance machining. Machinists and CNC operators in manufacturing, toolroom, and production environments install this end mill for precision contouring and profiling work.

This end mill suits short-reach, high-precision applications in steel and cast iron workpieces in CNC machining centers and manual mills. The straight-cylindrical shank with a 6 mm shank diameter and h5 tolerance ensures secure tool holding in standard collet chucks and shrink-fit holders. The extended-reach neck design, with a 3.70 mm neck diameter and 8 mm reach length, allows access to tighter features without sacrificing rigidity. It is appropriate for mold work, die machining, and general component profiling where consistent corner geometry is critical.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention in ferrous materials
• HXT coating provides enhanced wear and heat resistance during aggressive cuts
• 0.3 mm corner radius reduces edge chipping and extends tool life versus sharp-corner styles
• 4-flute, right-hand spiral, centercutting design supports both plunge and peripheral milling
• Extended-reach neck at 3.70 mm diameter and 8 mm reach for access to confined features
• Series JH142 short-length geometry balances stiffness and versatility for steel and cast iron

Compatibility

Designed for use in standard CNC machining centers and manual mills accepting a 6 mm straight-cylindrical shank. Primary workpiece materials are steel and cast iron per material codes P and K.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a calibrated collet or shrink-fit holder sized to the 6 mm shank diameter to maintain runout within acceptable limits. Verify tool projection and reach clearance before initiating a cutting cycle to avoid interference with workpiece features.
