Accupro 12276827 Square End Mill 0.05 in 4 Flute Carbide

Product Description

The ACCUPRO 12276827 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.05 inch cutting diameter, 0.15 inch length of cut, and a 4-flute right-hand spiral configuration, this end mill delivers clean square-shoulder cuts in tight tolerances. The micrograin carbide construction provides hardness and wear resistance suitable for ferrous and non-ferrous materials. A 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces. The bright, uncoated finish makes it a cost-effective choice for general-purpose milling where specialized coatings are not required.

This end mill is used in CNC machining centers and manual mills for finish milling, slotting, and profiling operations. Its 0.05 inch diameter makes it well-suited for fine-detail work, micro-machining, and die or mold work where small-radius features are required. The 1/8 inch shank diameter fits standard collets commonly found in production and job-shop environments. Machinists and CNC operators working on precision components will find the regular-length geometry appropriate for most standard-reach applications.

Key Features

• 0.05 inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• 4-flute right-hand spiral design with 30-degree helix angle for smooth chip flow
• Solid micrograin carbide construction for hardness and extended tool life
• Center-cutting design allows plunge entry as well as peripheral milling
• Bright, uncoated finish suitable for general-purpose milling applications
• Single-end, regular-length configuration at 1.5 inches overall length

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with collets or tool holders accepting a 1/8 inch shank diameter. Suitable for general-purpose square-shoulder milling, slotting, and profiling in metalworking environments.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Confirm collet size matches the 1/8 inch shank diameter and tighten to the tool holder manufacturer's specified procedure. Do not exceed the recommended length-of-cut range of 0.10 to 0.20 inches for this tool geometry.
