Sgs 30026 Square End Mill 3/4 in 4 Flute Solid Carbide Altin

Product Description

The SGS 30026 is a solid carbide square end mill designed for precision milling operations across a broad range of workpiece materials. Built on SGS Series 1 geometry, it features a 3/4 inch cutting diameter, a 1-1/2 inch length of cut, and a 4 inch overall length with a 3/4 inch straight cylindrical shank. The micrograin carbide substrate supports an AlTiN coating, which extends tool life in demanding cutting environments. With four flutes, a 30-degree helix angle, and a variable index configuration, this end mill balances chip evacuation with surface finish quality. It is centercutting, allowing plunge entry, and runs right-hand cut with right-hand flute geometry.

This end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys as indicated by its primary workpiece material codes. It fits standard CNC machining centers and manual knee mills equipped with an ER or similar collet system accepting a 3/4 inch shank. Regular-length geometry makes it a practical choice for slotting, profiling, and pocket milling where rigidity and runout control are priorities. Machinists in job shops, aerospace component manufacturing, and general metalworking will find this tool applicable to a wide range of production and prototype work.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in ferrous and high-temp alloy applications
• Centercutting design allows direct plunge entry without pre-drilling
• Variable index flute spacing reduces harmonic chatter during aggressive cuts
• 30-degree helix angle balances cutting forces and chip flow
• Right-hand cut and right-hand flute geometry compatible with standard CNC spindle rotation

Compatibility

Compatible with CNC machining centers and manual mills accepting a 3/4 inch straight cylindrical shank. Rated for use on workpiece material categories H, K, M, N, P, and S, covering hardened steels, cast iron, stainless steel, non-ferrous metals, carbon steels, and heat-resistant superalloys.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures. Secure the shank in a collet chuck, end mill holder, or shrink-fit holder to the manufacturer-recommended engagement depth, ensuring runout is within acceptable limits before cutting. Verify spindle direction is set to right-hand rotation before engaging the workpiece. Always power down and lock out the spindle before changing tooling.
