Harvey Tool 945612-C3 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The HARVEY TOOL 945612-C3 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 3/16 inch cutting diameter and a 9/32 inch length of cut, this single-end tool delivers accurate, flat-bottomed cuts in a compact form factor. The AlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. A 30-degree helix angle and three-flute geometry provide a balance of chip evacuation and surface finish quality. The extended reach design, with a 3/4 inch reach length, gives machinists access to deeper features without sacrificing rigidity.

This end mill is suited for milling ferrous metals, hardened steels, stainless steel, and similar high-strength materials where coating performance matters. It is used in CNC machining centers and manual mills for slotting, profiling, and pocket milling operations. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. With an overall length of 3 inches and a 3/16 inch shank diameter, it fits standard collets and end mill holders used in production and job shop environments.

Key Features

• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• 3-flute geometry balances chip clearance with cut surface quality
• 30-degree right-hand helix angle for efficient cutting action
• Center-cutting capable, allowing plunge entry into workpieces
• Extended reach with 3/4 inch reach length for access to deeper features
• Solid carbide construction provides rigidity and wear resistance

Compatibility

Designed as an OEM-style replacement and direct-fit solid carbide square end mill for standard 3/16 inch collets and end mill holders used in CNC and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power off or in an e-stop state. Ensure the shank is fully seated and properly torqued in the collet or end mill holder per the toolholder manufacturer specifications. Inspect the cutting edges and coating before use; do not use chipped or damaged tooling. Follow applicable shop safety standards and machine tool operating procedures when setting speeds and feeds for the workpiece material.
