Accupro 14797482 Ball End Mill 0.07in 3 Flute Carbide

Product Description

The ACCUPRO 14797482 is a solid carbide ball end mill engineered for high-precision milling in tight geometries and miniature-scale applications. With a 0.07-inch cutting diameter and a 0.5-inch length of cut, this tool is built for detail work where larger tooling simply cannot fit. The micrograin carbide construction delivers rigidity and wear resistance at small diameters where tool deflection and chipping are the primary failure modes. Three flutes in a right-hand spiral configuration with a 30-degree helix angle provide efficient chip evacuation and a smooth finish on ferrous and non-ferrous materials. The uncoated finish makes it well-suited for use in applications where coating adhesion at sub-1/8-inch diameters is a concern.

This end mill is designed for CNC machining centers and manual mills handling fine detail work in mold and die, medical component, aerospace, and electronics applications. The 1/8-inch shank diameter fits standard miniature collet systems. At 2.5 inches overall length, the tool offers extended reach beyond standard short-series geometry. Machinists working on 3D contoured surfaces, radii, and pocket floors will find this a direct fit for finishing and semi-finishing passes requiring a true ball-nose profile.

Key Features

• 0.07-inch cutting diameter for miniature and micro-scale milling operations
• Solid micrograin carbide construction for rigidity and extended tool life at small diameters
• 3-flute, right-hand spiral design with 30-degree helix for efficient chip evacuation
• 0.5-inch length of cut suitable for shallow pocket and contour finishing work
• 2.5-inch overall length provides extended reach in the miniature series
• Uncoated finish compatible with a broad range of work materials without coating-related adhesion concerns

Compatibility

Designed as a miniature-series single-end ball end mill compatible with 1/8-inch collet systems on CNC machining centers and manual milling machines set up for small-diameter tooling.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Use a collet or toolholder rated for the 1/8-inch shank diameter and verify runout with a dial indicator before initiating a cut. At sub-0.1-inch diameters, feed rate and spindle speed selection are critical to preventing tool breakage — follow the manufacturer or tooling supplier recommended cutting parameters for the specific work material.
