Sgs 46881 Corner Radius End Mill 4mm 4 Flute Carbide

Product Description

The SGS 46881 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining applications. It features a 4 mm cutting diameter, an 11 mm length of cut, and a 0.5 mm corner radius that reduces stress concentration at the cutting edge and extends tool life. The variable helix geometry minimizes chatter and improves surface finish across a range of materials. With four flutes and a TiN coating, this end mill handles both roughing and finishing passes in a single tool. It is part of the SGS Z-Carb-AP ZPMC series and is intended for use in CNC machining centers with standard end mill holders.

This end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The single-end, right-hand cutting configuration fits standard vertical and horizontal CNC setups. Its 6 mm straight-cylindrical shank seats securely in standard end mill holders, making it appropriate for precision job shops, tool and die work, and aerospace or industrial component machining where tight tolerances and consistent edge geometry are required.

Key Features

• 4 mm cutting diameter with 0.5 mm corner radius for reduced edge chipping
• Variable helix design reduces vibration and improves chip evacuation
• Solid micrograin carbide substrate for rigidity and wear resistance
• TiN coating increases surface hardness and extends tool life in ferrous and hard materials
• Four flutes support both roughing and finishing operations
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed for use with standard end mill holders. Compatible with machining applications involving steel, stainless steel, cast iron, superalloys, titanium, and hard materials per ISO material codes P, M, K, S, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Seat the 6 mm shank fully into the end mill holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before production cuts, as excessive runout will accelerate wear and degrade corner radius tolerance.
