Sgs 30117 Square End Mill 9/64 in 4 Flute Solid Carbide

Product Description

The SGS 30117 is a solid carbide square end mill designed for precision milling of a wide range of workpiece materials. With a 9/64 inch (0.1406 inch decimal) mill diameter and a 4-flute, right-hand spiral configuration, this tool delivers clean, accurate cuts in ferrous and non-ferrous metals, high-temperature alloys, and composite materials. A 30-degree helix angle promotes efficient chip evacuation and reduces heat buildup during cutting. The micrograin carbide substrate provides the wear resistance and edge retention required in demanding production environments. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual milling machines.

This end mill is suited for slotting, profiling, and contouring operations in applications requiring a small-diameter tool. The regular-length configuration keeps it practical for standard workholding setups without sacrificing rigidity. The bright, uncoated finish makes it a versatile option across a broad set of materials. Primary workpiece material codes H, K, M, N, P, and S indicate compatibility with hardened steels, cast irons, stainless steels, non-ferrous materials, steel alloys, and high-temperature alloys. Variable index spacing reduces harmonic vibration during cuts, improving surface finish quality.

Key Features

• Solid micrograin carbide construction for high wear resistance and edge retention
• 4-flute, right-hand spiral geometry with 30-degree helix angle for efficient chip evacuation
• Variable index flute spacing to reduce chatter and improve surface finish
• Center-cutting capable, allowing direct plunge entry into workpiece material
• Bright uncoated finish suitable for broad material compatibility
• Straight cylindrical shank for standard collet and end mill holder mounting

Compatibility

Designed for use with standard collets and end mill holders accepting a 3/16 inch straight cylindrical shank. Rated for primary workpiece material codes H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous materials, steel alloys, and high-temperature alloys per SGS Series 1 specifications.

Installation Notes

Install this end mill in a clean, dry collet or end mill holder rated for the 3/16 inch shank diameter; verify runout before commencing cuts. Power down and lock out the machine spindle before inserting or removing any tooling. Confirm that the holder clamping torque meets the machine tool manufacturer specifications. Inspect the cutting edges before each use and replace the tool if chipping or excessive wear is observed.
