Accupro 14797218 Square End Mill 0.055 in 3 Flute Carbide

Product Description

The ACCUPRO 14797218 is a solid carbide square end mill designed for precision milling in a wide range of materials. With a 0.055-inch cutting diameter and a 0.082-inch length of cut, this tool is built for fine detail work and tight-tolerance applications. The three-flute, spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate provides hardness and wear resistance suited to demanding milling conditions. A 1/8-inch shank diameter and 2.5-inch overall length make it compatible with standard collet systems found on CNC mills and manual machining centers. The centercutting design allows plunge entry directly into the workpiece.

This end mill is well suited for slotting, profiling, and pocket milling in precision machining environments, including job shops, tool rooms, and production floors. The extended reach configuration, with a 0.825-inch neck length and 0.660-inch reach length, allows access to deeper features without tool interference. The right-hand cut and right-hand flute direction are standard for conventional CNC and manual milling setups. The uncoated finish is appropriate for use in ferrous and non-ferrous materials where coating is not required or where re-sharpening is planned.

Key Features

• 0.055-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• Three spiral flutes at a 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for hardness and edge retention
• Centercutting design enables direct plunge entry into the workpiece
• Extended reach with 0.825-inch neck length and 0.660-inch reach length for deep-feature access
• Right-hand cut and right-hand flute direction for standard CNC compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 1/8-inch shank collet systems on CNC machining centers and manual mills requiring a small-diameter square end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and at rest before inserting or changing tooling. Secure the shank firmly in the collet to the full grip depth, staying within the reach length limits to avoid deflection. Follow your machine tool manufacturer guidelines for speeds and feeds appropriate to the workpiece material and this tool diameter.
