Accupro 12178896 Square End Mill 0.5 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12178896 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, it delivers the hardness and edge retention required for demanding cuts in ferrous and non-ferrous materials. The nACRo coating reduces friction and extends tool life in high-speed applications. With a 0.5-inch mill diameter, a 1-inch length of cut, and a 40-degree helix angle, this end mill is suited for aggressive material removal while maintaining a clean finish. It is a single-end, center-cutting tool with right-hand cut and right-hand spiral flute geometry.

This end mill fits standard milling machines, CNC machining centers, and knee mills commonly found in job shops, tool rooms, and production environments. The 0.5-inch shank diameter seats directly in standard ER or side-lock collet holders. Its regular-length profile and 3-inch overall length make it a straightforward drop-in for general-purpose profiling, slotting, and peripheral milling tasks. Machinists and CNC operators working in production or maintenance environments will find it well-suited to everyday cutting work where consistent tolerances matter.

Key Features

• Solid micrograin carbide construction for edge hardness and wear resistance
• nACRo finish coating for reduced friction and extended tool life in coated-tool applications
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Center-cutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand flute for standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as a standard-shank replacement end mill for use in any milling machine or machining center accepting a 0.5-inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from the collet or toolholder. Ensure the shank is fully seated and the collet is torqued to the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use — do not run a damaged carbide end mill.
