Accupro 14797498 Ball End Mill 0.0312 in 4 Flute Carbide

Product Description

The ACCUPRO 14797498 is a miniature solid carbide ball end mill designed for precision milling operations requiring a small-diameter cutting tool. With a 0.0312-inch (1/32 inch) mill diameter and 4-flute geometry, this single-end tool delivers fine detail work in ferrous and non-ferrous materials. The micrograin carbide construction provides the rigidity and edge retention needed for tight-tolerance cuts. A 30-degree helix angle promotes smooth chip evacuation, and the bright uncoated finish suits a wide range of base materials. The 0.093-inch length of cut (LOC) and extended-reach neck make it appropriate for slots, pockets, and contoured surfaces where access is limited.

This end mill is suited for CNC machining centers, high-speed spindles, and manual mills where fine detail and miniature feature work are required. Typical applications include mold and die work, medical device components, aerospace detail parts, and precision instrument manufacturing. The 1/8-inch shank diameter fits standard collets and tool holders common in small-diameter tooling setups. The extended-reach design with a 0.3150-inch neck length allows cutting in recessed areas without tool-holder interference.

Key Features

• 0.0312-inch (1/32 inch) ball nose diameter for fine detail and miniature feature milling
• 4-flute spiral geometry with 30-degree right-hand helix for efficient chip evacuation
• Micrograin solid carbide construction for rigidity and extended edge life
• Extended reach with 0.3150-inch neck length for access in deep or recessed features
• Bright uncoated finish compatible with a broad range of workpiece materials
• Single-end design with 1/8-inch shank diameter for standard collet compatibility

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8-inch collets and tool holders on CNC machining centers and manual mills requiring small-diameter tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the 1/8-inch shank in a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as runout is especially critical at this diameter.
