Accupro 12465856 Ball End Mill 0.065 in 4 Flute Carbide Altin

Product Description

The ACCUPRO 12465856 is a solid carbide ball end mill designed for precision milling of tight-tolerance features in hardened and difficult-to-machine materials. With a 0.0650-inch cutting diameter and a 0.0970-inch length of cut, this miniature single-end mill is built for small-radius contouring, slotting, and profiling in die and mold work, aerospace components, and medical part manufacturing. The 4-flute geometry paired with a 30-degree right-hand helix provides smooth chip evacuation and stable cutting action. An AlTiN coating delivers high heat resistance and extends tool life in dry or semi-dry cutting conditions. Micrograin carbide substrate ensures edge integrity at small diameters where rigidity margins are tight.

This end mill fits applications where small-feature accuracy is critical. The 0.0650-inch diameter is suited for fine-detail milling passes on hardened steel, stainless steel, titanium, and cast iron. The 1/8-inch shank accommodates standard collets on CNC machining centers, high-speed spindles, and toolroom mills. The miniature series designation places this tool in compact-geometry cutting applications where standard end mills are too large for the required feature size. It is typically purchased by tool-and-die makers, CNC machinists, and precision shop technicians working in tight-clearance or micro-machining environments.

Key Features

• 0.0650-inch ball nose diameter for small-radius contouring and fine-feature profiling
• Solid micrograin carbide substrate for edge strength and dimensional stability at miniature diameters
• AlTiN coating for high-temperature resistance and extended tool life in ferrous and exotic alloys
• 4-flute, 30-degree right-hand spiral geometry promotes smooth chip flow and surface finish
• Single-end design with 1/8-inch shank fits standard collet systems on CNC and manual mills
• Mill diameter tolerance of plus 0.0000 / minus 0.0010 inches supports close-tolerance finish work

Compatibility

Designed for use in CNC machining centers and high-speed spindles accepting a 1/8-inch round shank collet. Suited for milling hardened steels, stainless steels, titanium, and cast iron in die, mold, aerospace, and medical precision applications.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Seat the shank fully into the collet to the recommended gauge-line depth before torquing the collet nut to the machine specification. At miniature diameters, runout control is critical — verify total indicator runout before beginning a cut. Follow the tool manufacturer and machine builder recommendations for spindle speed, feed rate, and depth of cut for the specific workpiece material.
