Sgs 31656 Square End Mill 0.25 in 4 Flute Solid Carbide

Product Description

The SGS 31656 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. Built from micrograin carbide and coated with titanium nitride (TiN), it delivers extended tool life and consistent cutting performance. The 4-flute, 30-degree helix spiral geometry with a variable index reduces chatter and improves surface finish. The stub-length configuration keeps the tool rigid under load. With a 0.25-inch diameter and 0.5-inch length of cut, it is suited for slotting, profiling, and peripheral milling where accuracy and tool stability are critical.

This end mill is center-cutting, right-hand cut with right-hand flute direction, and mounts on a straight cylindrical shank. It is used in CNC machining centers and manual milling machines across job shops, production facilities, and tool rooms. The Series 16 designation places it within a specific SGS product family optimized for use across multiple workpiece material categories including ferrous, non-ferrous, heat-resistant, and high-temperature alloys.

Key Features

• Micrograin solid carbide construction for wear resistance and rigidity
• Titanium nitride (TiN) coating extends tool life and reduces friction
• 30-degree helix angle with variable index for reduced chatter and improved chip evacuation
• 4-flute spiral geometry supports both slotting and profiling operations
• Center-cutting design allows plunge entry into workpieces
• Stub-length configuration maximizes stiffness and minimizes deflection

Compatibility

Compatible with primary workpiece material codes H, K, M, N, P, and S, covering a broad range of ferrous, non-ferrous, heat-resistant, and superalloy materials. Designed for use in standard 1/4-inch collet or toolholder systems on CNC and manual milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the milling machine is powered down and the spindle is fully stopped before changing tooling. Secure the straight cylindrical shank in a clean, properly sized collet or end mill holder, and verify runout before cutting. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting speeds and feeds.
