Sgs 46821 Corner Radius End Mill 6mm 4 Flute Carbide

Product Description

The SGS 46821 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining applications. It features a 6 mm cutting diameter, an 8 mm length of cut, and a 0.5 mm corner radius that helps reduce stress concentration at the cutting edge and extend tool life. The 4-flute variable helix geometry supports both roughing and finishing passes in a single tool, while the extended reach design accommodates deeper pockets and stepped features. The straight-cylindrical shank measures 6 mm in diameter with an h6 tolerance for consistent toolholder engagement. This end mill is intended for use by machinists and tool-and-die professionals working on CNC milling equipment.

This end mill is engineered for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The short length type and 24 mm reach length make it well suited for pocketing, profiling, and contouring operations on vertical and horizontal machining centers where rigidity and precision are priorities. The variable helix and variable index design help reduce chatter during high-feed operations, making it a practical choice for production environments where consistent surface finish and dimensional accuracy are required across multiple workpiece materials.

Key Features

• 6 mm cutting diameter with 0.5 mm corner radius for edge strength and reduced workpiece stress
• 4-flute variable helix and variable index geometry reduces chatter and improves surface finish
• Solid micrograin carbide construction for rigidity and wear resistance in hard and abrasive materials
• Extended reach design with 24 mm reach length suits deeper pockets and stepped features
• Single-end, right-hand cut, right-hand flute direction with straight-cylindrical h6 shank
• Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials (P, M, K, S, H material codes)

Compatibility

Designed for use with standard end mill toolholders accepting a 6 mm straight-cylindrical shank with h6 tolerance. Belongs to the SGS ZPMC series for steel, stainless steel, cast iron, superalloys, titanium, and hard material applications.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer guidelines for setscrew torque and runout verification. Power down and lock out the spindle before loading or unloading the tool. Confirm shank engagement depth meets the toolholder minimum grip length before operation. Inspect the cutting edges and corner radius for chips or wear before each use.
