Accupro 14797112 Square End Mill 3/64 in 2 Flute Carbide

Product Description

The ACCUPRO 14797112 is a solid carbide square end mill designed for precision milling of small-diameter features in metal, composite, and plastic workpieces. With a 3/64 inch (0.0500 inch) cutting diameter and a 0.15 inch length of cut, this tool handles tight-tolerance slotting, profiling, and contouring where larger tools cannot reach. The 1/8 inch shank diameter and 1-1/2 inch overall length make it compatible with standard collet chucks and micro-tooling setups. Micrograin carbide construction provides the rigidity and edge retention needed at this scale. Installed by machinists and CNC operators in production and job-shop environments.

This end mill is suited for light-duty milling operations on aluminum, brass, steel, and engineered plastics where small-feature work demands precise tool geometry. The 30-degree right-hand spiral flute design promotes efficient chip evacuation in shallow pockets and slots. The extended reach configuration, with a 0.50 inch reach length, allows access to recessed features without sacrificing rigidity at the cutting edge. It is appropriate for CNC machining centers and manual knee mills equipped with appropriate micro-collet tooling. Single-end geometry means the tool is replaced when the cutting end is worn.

Key Features

• Solid micrograin carbide construction for improved edge retention and rigidity at small diameters
• 2-flute, right-hand spiral design with 30-degree helix angle for effective chip evacuation
• Centercutting geometry allows plunge entry directly into the workpiece
• Extended reach with 0.50 inch reach length for access to recessed or deep-pocket features
• Uncoated finish suitable for non-ferrous metals and plastics where coating buildup is a concern
• Mill diameter tolerance of +0.0000 / -0.0010 inch for consistent close-tolerance fitment

Compatibility

Designed for use in standard 1/8 inch collet chucks and micro-toolholders on CNC machining centers and manual mills. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

This tool is installed by machinists or CNC operators following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/8 inch shank fully and evenly in the collet to the recommended gauge-line depth before torquing the collet nut. At this diameter, excessive feed rates or inappropriate speeds significantly increase the risk of tool breakage — refer to the carbide manufacturer speed and feed tables for the specific workpiece material.
