Accupro 14981772 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The ACCUPRO 14981772 is a solid carbide square end mill designed for precision milling in steel and other ferrous materials. Built to Series 524 standards, this single-end tool features a 1/16 inch (0.0625 inch) mill diameter with four flutes and an AlTiN coating that improves heat resistance and tool life at elevated cutting speeds. The extra long length configuration provides extended reach into deep pockets and narrow cavities where standard-length end mills cannot access. It is installed and operated by machinists and CNC programmers in production and job shop environments.

This end mill is suited for high-speed milling operations in steel and similar workpiece materials where a small-diameter, high-flute-count tool is required. The 3/8 inch length of cut and 1/8 inch straight shank make it compatible with standard collet chucks and ER-style toolholders. The right-hand cutting and right-hand spiral flute geometry, combined with a 30-degree helix angle, promote efficient chip evacuation in slotting and profiling applications. It is a single-end tool, so once worn on the cutting end it is replaced rather than flipped.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel cutting
• AlTiN coating enhances heat resistance and extends tool life at higher surface speeds
• 4-flute, right-hand spiral geometry at 30-degree helix for effective chip evacuation
• Extra long overall length of 2.5 inches provides reach into deep pockets and cavities
• Centercutting design allows plunge milling in addition to peripheral and slot cuts
• 1/8 inch straight shank fits standard ER collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills equipped with collet chucks or end mill holders accepting a 1/8 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling practices. Ensure the machine spindle is fully stopped and locked out before seating or removing the tool from its holder. Verify collet or holder bore size matches the 1/8 inch shank diameter before tightening. Inspect the cutting edges and coating for damage before each use, as solid carbide tools are brittle and should not be subjected to interrupted cuts or excessive runout beyond the holder manufacturer specifications.
