Accupro 14883470 Square End Mill 1/64 in 4 Flute Carbide

Product Description

The ACCUPRO 14883470 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a mill diameter of 0.0156 inches (1/64 inch) and a 4-flute configuration, this tool delivers clean, accurate cuts in tight tolerances. The AlTiN coating provides heat resistance and extended tool life in hard and abrasive materials. A 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This end mill is center-cutting, allowing plunge entry, and features an extended reach design suitable for deep-pocket and contour milling operations. It is installed and operated by machinists and CNC tooling professionals.

This end mill is suited for high-speed milling of ferrous and non-ferrous metals, hardened steels, and alloys in both production and job-shop environments. The micrograin carbide substrate provides the rigidity and edge retention needed for fine-feature work. With a 0.045-inch length of cut and a 1/8-inch shank diameter, it is well matched to small-diameter toolholders and high-RPM spindle setups. The right-hand cut and right-hand flute spiral are standard for conventional CNC milling center configurations.

Key Features

• 0.0156-inch (1/64 inch) mill diameter for fine-feature and micro-milling applications
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• AlTiN coating for elevated heat resistance and extended tool life in hard materials
• Center-cutting geometry allows direct plunge entry without pre-drilled pilot holes
• Extended reach construction supports deep-pocket and contour milling operations
• Micrograin solid carbide substrate for maximum rigidity and edge retention

Compatibility

Designed as an OEM-style replacement and standard tooling option compatible with 1/8-inch straight shank toolholders used in CNC milling machines and machining centers configured for right-hand cutting tools.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a collet or endmill holder to the toolholder manufacturer's specified clamping procedure. Inspect the cutting edges and coating for damage before each use, as micro-diameter carbide end mills are susceptible to chipping if mishandled.
