Sgs 49181 Square End Mill 2.5mm 4 Flute Altin Carbide

Product Description

The SGS 49181 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. It features a 2.5 mm cutting diameter, a 5 mm length of cut, and four right-hand spiral flutes with a 30-degree helix angle. The micrograin carbide substrate is finished with an AlTiN coating, which improves heat resistance and extends tool life in high-temperature cutting environments. At 38 mm overall length with a 3 mm straight-cylindrical shank, this stub-length end mill offers high rigidity and reduced deflection. It is centercutting and suitable for slotting, profiling, and plunge operations. Installation and use are handled by machinists and CNC operators in job shop and production environments.

This end mill is classified as stub length in the SGS Series 16M lineup. It is intended for milling operations on a broad range of workpiece materials, including hardened steels, cast iron, stainless steel, non-ferrous metals, and superalloys, corresponding to ISO material groups H, K, M, N, P, and S. The right-hand cut and right-hand flute direction are standard for conventional CNC machining centers and manual knee mills. The stub length profile makes it particularly well suited for setups where tool overhang must be minimized to maintain dimensional accuracy.

Key Features

• 2.5 mm cutting diameter with plus 0.000 / minus 0.050 mm diameter tolerance for precise fits
• AlTiN coating provides thermal protection and wear resistance in ferrous and high-temp alloy cuts
• Micrograin solid carbide substrate delivers hardness and edge retention over extended run times
• 30-degree helix angle and 4 spiral flutes balance chip evacuation with surface finish quality
• Centercutting geometry allows direct plunge entry without pre-drilling
• Stub length (Series 16M) design maximizes rigidity and minimizes vibration in tight setups

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3 mm straight-cylindrical shank. Compatible workpiece material groups include H, K, M, N, P, and S per ISO classification, covering hardened steels, cast irons, stainless steels, non-ferrous materials, carbon steels, and superalloys.

Installation Notes

This end mill is installed and operated by machinists using appropriate collet chucks or end mill holders rated for the 3 mm shank diameter. Verify runout at the tool holder before cutting, as excess runout accelerates edge wear on small-diameter carbide tools. Follow machine tool manufacturer guidelines for spindle speed and feed rate based on workpiece material and depth of cut. Handle carbide tooling carefully to avoid chipping the cutting edges during storage and setup.
