Sgs 30826 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The SGS 30826 is a solid carbide square end mill designed for precision milling operations across a range of workpiece materials. It features a 1/4-inch cutting diameter with a 3/4-inch length of cut, a 1/4-inch straight cylindrical shank, and a 2-1/2-inch overall length. The three-flute, right-hand spiral geometry runs at a 30-degree helix angle, and the AlTiN coating improves heat resistance and tool life in demanding cuts. Micrograin carbide construction supports tight tolerances, with a mill diameter tolerance of +0.0001 to -0.002 inches. This is a centercutting tool, suitable for plunge entry as well as peripheral and slot milling.

The SGS 30826 fits into regular-length milling programs on CNC machining centers and manual knee mills. Its material compatibility codes cover hardened steels, cast irons, stainless steels, nonferrous metals, general steels, and high-temperature alloys (workpiece material codes H, K, M, N, P, and S). The 1/4-inch shank fits standard ER collets and end mill holders commonly found in production and job-shop environments. This tool is suited to finishing and light-to-medium roughing passes where dimensional accuracy and surface finish matter.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life
• 3-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Shank diameter tolerance of -0.0001 to -0.0004 inches for secure, repeatable tool holding

Compatibility

Compatible with workpiece material codes H, K, M, N, P, and S as specified by SGS Series 5 classification, covering hardened steels, cast irons, stainless steels, nonferrous metals, general steels, and high-temperature alloys. Fits any standard 1/4-inch end mill holder or ER collet chuck.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Verify collet or holder runout before production use to stay within the stated diameter tolerance. Follow the machine tool and holder manufacturer specifications for drawbar torque and collet seating.
