Sgs 39019 Square End Mill 5/32 in 4 Flute Solid Carbide

Product Description

The SGS 39019 is a single-end square end mill designed for precision material removal in machining operations. Built from micrograin solid carbide and coated with TiCN for extended tool life, it features 4 spiral flutes with a 30-degree helix angle and a variable index geometry to reduce chatter. The mill diameter is 0.1563 inches (5/32 inches) with a 1/2-inch length of cut and a 2-inch overall length. It is centercutting, allowing plunge entry, and cuts in a right-hand direction. This tool is intended for use by machinists and tool-and-die professionals on CNC mills and manual knee mills.

The SGS 39019 is suited for a range of workpiece materials including cast iron, non-ferrous metals, stainless steel, high-temperature alloys, titanium, and steel — corresponding to ISO material groups H, K, M, N, P, and S. The straight-cylindrical shank and compact regular-length profile make it a practical choice for tight-clearance slots, profiling passes, and contour milling in both production shop and job-shop environments. It is sold as a single unit.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in abrasive and hard materials
• 30-degree helix angle with variable index for reduced vibration and improved surface finish
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute spiral for standard CNC mill compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in close-tolerance applications

Compatibility

Designed as a standard straight-shank square end mill for use in collet chucks, end mill holders, and shrink-fit tooling systems that accept a 3/16-inch shank diameter. Compatible with workpiece material groups H, K, M, N, P, and S per ISO material classification as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked before inserting or removing the tool from its holder. Verify collet or holder bore matches the 3/16-inch shank diameter and that runout is within acceptable tolerance before cutting. Consult manufacturer feeds-and-speeds data for the specific workpiece material before first use.
