Accupro 14797343 Square End Mill 0.0394 in 4 Flute Carbide

Product Description

The ACCUPRO 14797343 is a single-end, solid carbide square end mill designed for precision milling in metal, composites, and other hard materials. It features a 0.0394-inch (1.00 mm) mill diameter, a 0.117-inch length of cut, and a 1/8-inch shank diameter, making it suited for fine-detail work in tight geometries. Built from micrograin solid carbide, it delivers excellent wear resistance and edge retention at small diameters. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. It arrives uncoated with a bright finish, ready for use with compatible cutting fluids or in dry conditions depending on the workpiece material and machine setup.

This end mill is intended for use in CNC machining centers, manual knee mills, and precision toolroom machines where small-diameter work is required. Typical applications include slotting, profiling, and finishing passes in aluminum, brass, steel, and engineering plastics. The centercutting design allows plunge entry into the workpiece. It is most commonly deployed by machinists and toolmakers working on intricate parts, mold cavities, or prototype components that demand tight tolerances at very small feature sizes.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life at micro diameters
• 0.0394-inch (1.00 mm) mill diameter for fine-detail and micro-feature machining
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design enables direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute configuration for standard spindle use
• Bright/uncoated finish compatible with a wide range of workpiece materials

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC and manual milling machines accepting a 1/8-inch shank diameter collet or end mill holder. Part of the ACCUPRO ASQSC4-CC-30H series.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with small-diameter tooling and CNC or manual mill operation. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a properly sized collet or end mill holder rated for a 1/8-inch shank and torque the retention nut per the collet manufacturer specifications. Small-diameter carbide end mills are brittle and susceptible to breakage from excessive runout, improper feed rates, or unsupported tool length — verify runout at the collet before operation.
