Sgs 93337 Square End Mill 5/16 in 4 Flute Solid Carbide

Product Description

The SGS 93337 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. Built to Series 1EL-AD specifications, it features a 0.3125 inch (5/16 inch) cutting diameter, a 1.625 inch length of cut, and a 4 inch overall length that places it in the extra-long category. The 30-degree spiral helix angle promotes efficient chip evacuation and reduces cutting forces during aggressive passes. A DLC (Diamond-Like Carbon) coating extends tool life by lowering friction and improving wear resistance. This end mill is intended for use by machinists, tool-and-die makers, and CNC operators working in production or job-shop environments.

The 93337 is suited for slotting, profiling, and peripheral milling operations where extended reach is needed to access deep pockets or tall workpiece features. The extra-long length of cut range of 1.5 to 2.0 inches accommodates stepped or tiered cavity work. The variable index flute spacing reduces harmonic chatter during interrupted cuts or high-feed passes. Straight-cylindrical shank with h6 tolerance ensures consistent runout in standard collet and end-mill holders.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention
• DLC coating reduces friction and extends tool life in abrasive materials
• 30-degree helix angle promotes positive chip flow and smooth cutting action
• Variable index flute geometry minimizes chatter in demanding milling conditions
• Centercutting design allows plunge entry into workpiece material
• Extra-long length of cut supports deep pocket and cavity milling applications

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual milling machines accepting a 0.3125 inch straight-cylindrical shank with h6 tolerance.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or end-mill holder to the minimum insertion depth recommended by the toolholder manufacturer to avoid deflection. Verify spindle runout before initiating cuts, particularly given the extra-long reach. Follow your machine tool manufacturer guidelines and applicable shop safety procedures when changing cutting tools.
