Sgs 30040 Ball End Mill 5/32 in 4 Flute Solid Carbide Altin

Product Description

The SGS 30040 is a solid carbide ball end mill designed for high-performance milling in demanding metalworking applications. With a 5/32-inch (0.1563-inch) cutting diameter and 4 flutes arranged in a right-hand spiral, it delivers efficient chip evacuation and smooth surface finishes. The AlTiN coating provides thermal resistance and extended tool life when cutting ferrous and exotic alloys. A 30-degree helix angle balances cutting forces across the flute length, making this mill well-suited for both roughing and finishing passes. It is a single-end tool manufactured from micrograin solid carbide stock for consistent edge geometry and wear resistance.

This end mill is intended for CNC machining centers and manual milling machines used in precision metalworking environments. It is appropriate for cutting a wide range of workpiece materials including hardened steels, cast irons, stainless steels, non-ferrous metals, carbon steels, and high-temperature alloys, as indicated by its primary workpiece material codes H, K, M, N, P, and S. Machinists, toolroom technicians, and CNC programmers working in job shop, aerospace, medical device, and general manufacturing settings will find this tool suitable for finishing profiles, slots, and contoured surfaces. Variable index geometry reduces harmonic vibration during cut.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• AlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions
• 4-flute, right-hand cutting and flute direction for efficient chip removal
• 30-degree helix angle balances cutting forces for stable milling performance
• Variable index design reduces chatter and harmonic vibration
• Standard length configuration with 1/2-inch length of cut and 2-inch overall length

Compatibility

Designed for use in standard CNC and manual milling applications. Compatible with workpiece material categories H (hardened steels), K (cast irons), M (stainless steels), N (non-ferrous metals), P (carbon and alloy steels), and S (high-temperature and titanium alloys). Accepts a 3/16-inch tool holder or collet.

Installation Notes

Installation is performed by a machinist or toolroom technician using a compatible collet or end mill holder sized for the 3/16-inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Verify runout with a dial indicator after tool installation to confirm proper seating. Observe recommended speeds and feeds for the workpiece material and coating type per the manufacturer or machining reference to avoid premature edge wear or tool fracture.
