Accupro 12276836 Square End Mill 0.059 in 4 Flute Carbide

Product Description

The ACCUPRO 12276836 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.059 inch cutting diameter and a 0.177 inch length of cut, this tool is built for fine detail work, slotting, and profiling in tight geometries. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and stable cutting performance. Manufactured from micrograin solid carbide, it delivers rigidity and wear resistance suited to demanding production environments. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is suited for use in CNC machining centers and manual mills where small-diameter, high-precision cuts are required. The 0.125 inch shank diameter and 1.5 inch overall length make it compatible with standard 1/8 inch collets and tool holders. The centercutting design allows plunge entry, expanding its use in pocketing and drilling-style operations. It is well-suited for work in ferrous and non-ferrous metals, engineering plastics, and composites where tight tolerances and fine finishes are required.

Key Features

• 0.059 inch cutting diameter for fine detail and small-feature milling
• 4-flute spiral design with 30-degree helix for efficient chip removal
• Centercutting geometry enables direct plunge entry
• Micrograin solid carbide construction for extended tool life and dimensional stability
• Right-hand cut and right-hand flute for standard spindle operation
• Uncoated finish suitable for a broad range of work materials

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining centers and manual milling machines equipped with 1/8 inch collets or tool holders accepting a 0.125 inch shank diameter.

Installation Notes

Installation and use of this end mill should be performed by qualified machinists or CNC operators familiar with proper tooling procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet or tool holder. Confirm runout is within acceptable limits after seating the shank to avoid premature tool wear or breakage. At small diameters like 0.059 inches, excessive feed rates or improper speeds can result in tool fracture — always consult published speeds and feeds data for the specific work material.
