Sgs 32665 Square End Mill 1/2 in 5 Flute Solid Carbide Altin

Product Description

The SGS 32665 is a 5-flute solid carbide square end mill designed for high-performance milling in demanding metalworking applications. Built from micrograin carbide with an AlTiN (aluminum titanium nitride) finish, it delivers extended tool life at elevated cutting temperatures. The 0.5-inch diameter cuts to a length of 1.25 inches, and the overall length is 3 inches. The 45-degree helix angle combined with a variable index geometry reduces chatter and improves surface finish at aggressive feed rates. This tool is intended for use by machinists and CNC operators working in production or job-shop environments.

The 32665 is suited for milling hardened steels, stainless steels, cast irons, titanium alloys, high-temperature alloys, and general-purpose ferrous materials — corresponding to workpiece material codes H, K, M, P, and S. Its centercutting design allows plunge entry as well as conventional side milling and slotting. The straight cylindrical shank fits standard ER collet chucks, end mill holders, and shrink-fit toolholders with a 0.5-inch bore. It is a single-end, right-hand cut, right-hand flute configuration in SGS Series 55.

Key Features

• 5-flute micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating provides thermal protection for dry or minimal-lubrication cutting
• 45-degree spiral helix angle promotes efficient chip evacuation
• Variable index flute spacing reduces harmonic vibration during cutting
• Centercutting geometry enables direct plunge and ramping entry
• Right-hand cut and right-hand flute — standard CNC spindle compatible

Compatibility

Compatible with workpiece materials classified under codes H (hardened steels), K (cast irons), M (stainless steels), P (general steels), and S (high-temperature and titanium alloys). Fits any 0.5-inch bore toolholder; shank diameter tolerance is +0.00000 / -0.00043 inches.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool-change position is engaged before inserting or removing the end mill. Confirm toolholder runout is within acceptable limits before beginning a cut, as excess runout accelerates edge wear on a 5-flute tool. Follow the cutting tool manufacturer's recommended speeds and feeds for the specific workpiece material grade and do not exceed the rated depth of cut for the 1.25-inch length of cut.
