Sgs 30531 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The SGS 30531 is a solid carbide square end mill designed for precision material removal in milling operations across a wide range of workpiece materials. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and three right-hand spiral flutes with a 30-degree helix angle. The micrograin carbide construction provides the hardness and edge retention needed for demanding cuts. At 2.5 inches overall length with a 1/4 inch straight-cylindrical shank, this is a single-end, center-cutting tool built for consistent performance on manual mills, CNC machining centers, and knee mills. Machinists and tooling professionals install and operate this tool in production and job-shop environments.

This end mill is suited for milling operations on a broad spectrum of materials. The primary workpiece material codes listed are H, K, M, N, P, and S, covering cast iron, non-ferrous metals, stainless steel, steel, heat-resistant alloys, and similar categories. The Series 5 designation places it in a regular-length category, making it appropriate for general-purpose slotting, profiling, and peripheral milling where a compact, rigid tool is preferred over extended-reach configurations. It is compatible with standard 1/4 inch collets and tool holders used in common milling setups.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting geometry allows plunge entry into the workpiece
• Bright/uncoated finish suitable for use with or without cutting fluid
• 1/4 inch straight-cylindrical shank fits standard collets and end mill holders
• Right-hand cutting direction compatible with conventional milling machine spindle rotation

Compatibility

Designed for use with standard 1/4 inch collet chucks and end mill holders on manual mills and CNC machining centers. Compatible with workpiece material categories H, K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation is performed by a machinist or tooling technician using a compatible collet or end mill holder torqued per the machine tool manufacturer specifications. Ensure the machine spindle is fully stopped and the machine is powered down before changing tooling. Inspect the shank and collet bore for chips or debris before seating the tool. Observe recommended speeds and feeds for the specific workpiece material and tool diameter to avoid tool deflection or premature wear.
