Accupro 14883447 Square End Mill 5/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14883447 is a single-end square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, it delivers rigidity and wear resistance at small diameters. The 0.0781-inch (5/64 inch) cutting diameter and 0.625-inch (5/8 inch) length of cut make it well suited for fine detail work, slotting, and profiling in tight geometries. An AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. The 30-degree helix angle promotes efficient chip evacuation, and the three-flute geometry balances cutting speed with surface finish quality.

This end mill is intended for use in CNC machining centers, vertical mills, and manual milling machines where small-diameter, high-precision cutting is required. It is commonly applied in tool and die work, mold making, aerospace component machining, and general metalworking shops. The 1/8-inch shank diameter fits standard collets and tool holders sized for that bore. Right-hand cutting and right-hand flute direction follow conventional milling setup. Centercutting capability allows plunge entry, adding versatility to the application range.

Key Features

• Micrograin solid carbide construction for stiffness and edge retention at small diameters
• AlTiN coating for elevated heat resistance and extended tool life in ferrous and hardened materials
• Three flutes with 30-degree helix angle for efficient chip evacuation and improved finish
• Centercutting design allows direct plunge entry into workpieces
• Right-hand cut, right-hand spiral — compatible with standard CNC and manual mill setups
• 1/8-inch shank diameter fits common ER and straight-bore collet systems

Compatibility

Designed for use in any milling machine or machining center equipped with a collet or tool holder accepting a 1/8-inch shank diameter. Suitable for standard ER11, ER16, and comparable collet chuck systems.

Installation Notes

This tool is installed by a machinist or CNC operator using an appropriate collet chuck or end mill holder sized to the 1/8-inch shank. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the end mill. Confirm runout with a dial indicator after tightening to minimize premature tool wear at this small diameter. Follow machine manufacturer torque specifications for collet nuts and observe shop safety protocols for rotating tooling.
