Sgs 30535 Square End Mill 9/32 in 3 Flute Solid Carbide

Product Description

The SGS 30535 is a solid carbide square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built to Series 5 standards, this single-end tool features a 0.2813-inch (9/32 inch) cutting diameter, a 0.75-inch length of cut, and a straight cylindrical shank measuring 0.3125 inches (5/16 inch) in diameter. The three-flute, right-hand spiral design runs at a 30-degree helix angle, promoting efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers the edge retention and rigidity needed for tight-tolerance work across a wide range of workpiece materials.

This end mill is suited for slotting, peripheral milling, and plunge cutting operations in job shop, production, and toolroom environments. The centercutting geometry allows direct plunge entry without pre-drilling. It is appropriate for use in CNC machining centers and manual knee mills where a regular-length tool with a standard shank is required. Compatible workpiece materials include hardened steels, cast irons, stainless steels, aluminum alloys, non-ferrous metals, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S.

Key Features

• Solid micrograin carbide construction for extended tool life and edge sharpness
• Three right-hand spiral flutes at 30-degree helix angle for efficient chip flow
• Centercutting design allows direct plunge entry into workpiece
• Straight cylindrical shank with tight tolerance of +0.00000 / -0.00035 inches for secure tool holding
• Uncoated finish suitable for use with or without cutting fluid across multiple material types
• Regular length configuration balances reach and rigidity for general-purpose milling

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard ER collets, end mill holders, or shrink-fit tooling systems that accept a 5/16-inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool. Verify collet or holder bore size matches the 0.3125-inch shank diameter before clamping. Confirm runout with a dial indicator after tool installation to maintain dimensional accuracy and extend tool life.
