Sgs 39111 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The SGS 39111 is a single-end square end mill designed for precision milling operations across a wide range of metallic and non-metallic workpiece materials. Built from micrograin solid carbide and finished with a TiN coating, it delivers consistent edge performance and extended tool life. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.0938 inches in diameter with a 9/32-inch length of cut, this tool is suited for fine detail work and tight-tolerance slots, shoulders, and profiles. Licensed machinists and CNC operators are the primary users.

This end mill is designed for use in CNC machining centers and manual mills where small-diameter, close-tolerance cutting is required. The straight-cylindrical shank seats securely in standard collets and end mill holders. With a variable index geometry and centercutting capability, it handles plunge entries and interpolated paths. It is rated for use on material groups H, K, M, N, P, and S, covering hardened steels, cast irons, stainless, non-ferrous alloys, steel alloys, and high-temperature superalloys.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• TiN coating reduces friction and extends tool life on ferrous and non-ferrous materials
• 4 flutes with 30-degree right-hand helix for efficient chip removal and surface finish
• Centercutting geometry enables direct plunge and ramping operations
• Variable index flute spacing reduces chatter and harmonics during high-speed passes
• Straight-cylindrical shank fits standard collet and end mill holder systems

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual knee mills accepting a 1/8-inch straight-cylindrical shank, within SGS Series 1 tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Seat the shank to the full recommended engagement depth in the collet or holder to prevent pullout under load. Verify runout with a dial indicator after installation and before beginning the cut cycle.
