Sgs 39133 Square End Mill 17/64 in 4 Flute Solid Carbide

Product Description

The SGS 39133 is a solid carbide square end mill designed for precision milling in a wide range of metalworking applications. It features a 17/64 inch (0.2656 inch) cutting diameter with a 3/4 inch length of cut and a 5/16 inch straight-cylindrical shank. Overall length is 2-1/2 inches. The four-flute spiral design with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. A titanium nitride (TiN) coating improves surface hardness and wear resistance. The variable index geometry reduces harmonic vibration during cutting, extending both tool life and workpiece surface quality.

This end mill is suited for milling operations on cast iron, non-ferrous metals, stainless steel, heat-resistant alloys, and steel workpieces, as indicated by its primary workpiece material codes H, K, M, N, P, and S. It is centercutting, allowing plunge cuts in addition to peripheral and slot milling. Typical applications include contouring, profiling, and slotting on CNC machining centers and manual knee mills in job shop and production environments. The regular-length configuration fits standard tool holders without extended reach requirements.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• TiN finish coating for improved hardness and tool longevity
• Variable index flute spacing reduces chatter and vibration
• Centercutting design allows direct plunge entry into workpiece material
• 30-degree helix angle with spiral flutes for efficient chip evacuation
• Right-hand cut and right-hand flute configuration for standard spindle use

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/16 inch straight-cylindrical shank tool holders used in CNC and manual milling applications across Series 1 end mill specifications.

Installation Notes

This end mill is installed by machinists and tooling technicians using a compatible collet or end mill holder sized for a 5/16 inch shank. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank seating depth and holder runout with a dial indicator before cutting. Follow machine manufacturer guidelines for feeds, speeds, and depth of cut based on workpiece material.
