Sgs 39141 Square End Mill 21/64 in 4 Flute Solid Carbide

Product Description

The SGS 39141 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 21/64 inch (0.3281 inch) cutting diameter, a 1 inch length of cut, and a 3/8 inch straight-cylindrical shank, with an overall length of 2-1/2 inches. The 4-flute geometry with a 30-degree helix angle and TiN (Titanium Nitride) finish supports efficient chip evacuation and extended tool life. Variable index spacing reduces harmonic chatter during cuts. This tool is installed by machinists and CNC operators working in job shops, tool rooms, and production environments.

The SGS 39141 is suited for milling a broad range of workpiece materials, including hardened steels, cast irons, stainless steels, non-ferrous metals, titanium alloys, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. It is centercutting, allowing for plunge entry as well as conventional side milling. Right-hand cut and right-hand flute orientation are standard for use on conventional vertical and horizontal CNC milling machines. The regular-length classification makes it appropriate for general-purpose slotting, profiling, and peripheral milling operations.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in demanding materials
• TiN coating reduces friction and extends tool life in ferrous and non-ferrous applications
• 4-flute, 30-degree spiral flute design for balanced cutting and efficient chip removal
• Variable index flute spacing minimizes chatter and vibration during milling
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute for compatibility with standard CNC spindle rotation

Compatibility

Designed for use with standard 3/8 inch collet chucks or end mill holders on CNC machining centers and manual milling machines. Compatible with workpiece material codes H, K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank fully in a properly sized collet or end mill holder to the recommended engagement depth before operation. Confirm spindle rotation direction matches the right-hand cut orientation of this tool before starting the machine. Inspect the cutting edges and coating for wear or chipping before each use and replace the tool if damage is detected.
