Sgs 33143 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The SGS 33143 is a solid carbide square end mill designed for precision milling in a wide range of materials. It features a 0.125 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length, placing it in the extra long category for extended reach applications. The 4-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. Variable index spacing reduces harmonic vibration during cut. This tool is centercutting, allowing plunge entry, and is suited for right-hand spindle operation. Machinists and CNC operators working in production or job shop environments are the typical end users.

The SGS 33143 is intended for milling operations on a broad range of workpiece materials, including cast iron, non-ferrous metals, stainless steel, titanium alloys, and structural steels, as reflected by the material codes H, K, M, N, P, and S. Its extra long length of cut makes it well suited for deep pocket milling, slotting, and profiling passes where a standard-length end mill cannot reach. The straight cylindrical shank fits standard collet chucks and end mill holders with a 1/8 inch bore.

Key Features

• 0.125 inch mill diameter with mill diameter tolerance of +0.000/-0.002 inches
• 4 spiral flutes with 30-degree helix angle for efficient chip flow
• Variable index flute spacing reduces chatter and vibration
• Centercutting design permits direct plunge entry into workpiece
• Micrograin solid carbide construction for wear resistance and edge retention
• Extra long series (1EL) with 1 inch length of cut for deep-reach applications
• Uncoated finish; right-hand cut and right-hand flute configuration

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collet chucks or end mill holders. Compatible with workpiece material codes H, K, M, N, P, and S as specified by the manufacturer for Series 1EL tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or holder to the recommended gauge length before tightening to prevent runout. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Consult the machine tool manufacturer guidelines and applicable shop safety standards when setting feed rates and depths of cut for this tool diameter and length combination.
