Sgs 43449 Corner Radius End Mill 8mm 3 Flute Solid Carbide

Product Description

The SGS 43449 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. With an 8 mm cutting diameter, 20 mm length of cut, and a 0.5 mm corner radius, it delivers controlled edge protection while maintaining aggressive stock removal. The three-flute, variable helix geometry reduces harmonic vibration and improves chip evacuation. An AlTiN coating — marketed under SGS's Ti-NAMITE-A designation — provides thermal resistance and hardness retention at elevated cutting temperatures. This end mill is single-ended, right-hand cut, and built for roughing operations where tool life and dimensional stability matter.

This end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its coarse pitch and variable helix geometry make it a fit for roughing passes in ISO material groups P, M, K, S, and H. The straight cylindrical shank with h6 tolerance mates directly to standard end mill toolholders. Typical applications include mold and die work, aerospace component machining, and general-purpose metal removal where corner edge integrity is required throughout the cut.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating (Ti-NAMITE-A) for high-temperature performance and oxidation resistance
• Variable helix flute geometry reduces chatter and improves surface finish during roughing
• 0.5 mm corner radius protects cutting edges and reduces stress concentration at the tool tip
• Straight cylindrical shank with h6 tolerance for precise seating in standard toolholders
• Series 33MC roughing geometry optimized for steel, stainless steel, cast iron, superalloys, and titanium

Compatibility

Designed for use with standard end mill toolholders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material groups P, M, K, S, and H).

Installation Notes

Installation is performed by machinists or CNC setup technicians using a compatible end mill toolholder sized for an 8 mm shank. Ensure the toolholder bore and retention mechanism are clean and free of debris before seating the tool. Follow machine tool manufacturer torque specifications for set screws or collet nuts. Confirm runout is within tolerance before beginning a cut, as excessive runout accelerates corner radius wear and reduces tool life.
