Accupro 12463688 Ball End Mill 0.056 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12463688 is a miniature solid carbide ball end mill designed for precision milling operations in tight geometries and small-feature work. The ball nose profile produces curved surfaces, blended contours, and three-dimensional pocket details that flat-end mills cannot reach. At 0.056 inches in cutting diameter with a 0.168-inch length of cut (LOC), this tool is built for fine detail passes in hard and abrasive workpiece materials. Micrograin carbide construction gives the substrate higher edge retention and wear resistance compared to standard-grade carbide. The uncoated bright finish suits applications where coating buildup tolerance is tight or where re-sharpening is anticipated.

This end mill fits light-duty milling work on CNC machining centers and manual mills handling small-part production, mold and die detail work, prototype machining, and precision component manufacture. The miniature series designation indicates suitability for micro-scale features common in medical device, aerospace, and electronics-adjacent machining. The 1/8-inch shank diameter fits standard collet sets and ER-style toolholders commonly used in small-spindle machines and high-speed machining centers.

Key Features

• Ball nose geometry for contoured surface milling and 3D profiling
• Micrograin solid carbide substrate for edge retention in hard materials
• 2-flute, right-hand cutting and right-hand spiral flute configuration
• 30-degree helix angle balances chip evacuation and cutting load
• Single-end design; 1/8-inch shank diameter for standard collet compatibility
• Uncoated bright finish suitable for re-sharpening or low-coating-tolerance applications

Compatibility

Designed as an OEM-style miniature ball end mill compatible with standard 1/8-inch collets and ER-style toolholders used in CNC machining centers and small-spindle milling machines.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout at this diameter will accelerate edge chipping. Do not exceed the tool manufacturer recommended depth-of-cut or feed parameters for the workpiece material.
