Accupro 14797142 Square End Mill 1/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14797142 is a solid carbide square end mill designed for precision milling in tight-geometry applications. With a 1/64 inch (0.0156 inch) cutting diameter and a 0.022 inch length of cut, this tool is built for micro-scale material removal where dimensional accuracy is critical. The micrograin carbide substrate provides the rigidity and wear resistance required for small-diameter cutting. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation while maintaining smooth cutting action. The bright uncoated finish makes it well-suited for non-ferrous metals and applications where coating buildup would be a concern. Machinists and tool-and-die professionals working on precision components, molds, or intricate part features will find this tool applicable to close-tolerance work.

This end mill is intended for use in CNC machining centers, vertical mills, and precision benchtop machines where small-feature milling is required. The 1/8 inch shank diameter allows it to fit standard collets and toolholders commonly found in production and prototype shops. The extended reach design, with a 0.225 inch reach length and a 2.5 inch overall length, allows access to features in deeper pockets without sacrificing rigidity at the shank. It is a single-end tool with right-hand cut and right-hand flute orientation, center-cutting capable, and suitable for plunge entry into workpieces.

Key Features

• 1/64 inch (0.0156 inch) cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• Micrograin solid carbide construction for superior hardness and wear resistance at small diameters
• Three spiral flutes at 30-degree helix angle for efficient chip flow in micro-milling operations
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Extended reach design with 0.225 inch reach length for access to deeper features
• Bright uncoated finish compatible with non-ferrous materials and applications requiring minimal edge buildup

Compatibility

Designed for use with standard 1/8 inch collets and toolholders in CNC machining centers and precision milling machines. Part of the ACCUPRO ASQSC3-CCER series of solid carbide square end mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle and collet are clean and free of debris before seating the shank to maintain concentricity within acceptable runout tolerances. At this diameter, even minor runout will significantly impact tool life and cut quality, so collet condition and clamping force should be verified before operation. Always confirm spindle speed and feed rate settings are appropriate for the workpiece material and tool diameter before engaging the cut.
