Sgs 36142 Square End Mill 3/8 in 6 Flute Solid Carbide Altin

Product Description

The SGS 36142 is a 6-flute solid carbide square end mill designed for high-performance milling in hard and difficult-to-machine materials. With a 3/8 inch cutting diameter, a 13/16 inch length of cut, and a 4 inch overall length, this tool falls into the extra-long category and delivers extended reach without sacrificing rigidity. The AlTiN coating provides thermal protection and oxidation resistance, making it well suited for aggressive dry or near-dry cutting conditions. A 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is center-cutting, allowing direct plunge entry into a workpiece.

The SGS 36142 is intended for machining hard materials, designated workpiece material code H, including hardened steels and similar alloys. The straight-cylindrical shank measures 3/8 inch in diameter, matching the cutting diameter for straightforward tool holding. Spiral fluting with right-hand cut and right-hand flute geometry is standard for conventional vertical or horizontal milling setups. This tool fits production and job-shop environments where finish quality and tool life in hard materials are priorities.

Key Features

• 6-flute geometry increases feed rate capacity and improves surface finish in hard materials
• AlTiN coating enhances heat resistance and extends tool life in dry cutting applications
• 45-degree helix angle promotes efficient chip flow and reduces cutting forces
• Center-cutting design allows plunge milling without a pre-drilled entry hole
• Extra-long overall length of 4 inches provides extended reach for deep-pocket operations
• Solid carbide construction delivers rigidity and wear resistance superior to HSS tooling

Compatibility

Designed as a direct-fit replacement or production tool for standard 3/8 inch straight-shank tool holders, collet chucks, and end mill holders used in CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before installing or removing the end mill. Seat the shank fully in the collet or holder to the recommended grip length to minimize runout and tool pull-out risk. Verify tool holder bore cleanliness and check runout with a dial indicator before commencing cutting operations.
