Accupro 12465457 Ball End Mill 0.029 in 2 Flute Carbide

Product Description

The ACCUPRO 12465457 is a miniature solid carbide ball end mill designed for precision milling operations requiring a very small cutting diameter. With a 0.0290-inch mill diameter and a 0.0430-inch length of cut, this tool is built for intricate work in tight geometries. The 30-degree right-hand spiral helix promotes smooth chip evacuation, and the micrograin carbide construction delivers hardness and edge retention in demanding materials. The bright, uncoated finish suits applications where coating buildup would reduce dimensional accuracy at small scales. Machinists and tool-and-die professionals rely on this style of end mill for close-tolerance detail work.

This miniature ball end mill is suited for use in CNC machining centers, micro-milling operations, and precision mold work where small-radius profiles and fine surface finishes are required. The stub-length configuration keeps deflection low, making it appropriate for high-precision contour milling, engraving passes, and 3D profiling in ferrous and non-ferrous materials. The 1/8-inch shank diameter fits standard collet toolholders commonly used in precision milling setups.

Key Features

• 0.0290-inch ball nose diameter for fine-detail and small-radius milling
• Solid micrograin carbide construction for superior hardness and edge retention
• 2-flute, right-hand spiral design with 30-degree helix for efficient chip removal
• 0.0430-inch length of cut in a stub-length profile to minimize deflection
• Bright, uncoated finish suitable for dry cutting and dimensional-accuracy-critical applications
• Single-end configuration with 1/8-inch shank diameter for standard collet compatibility

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and precision milling equipment accepting a 1/8-inch collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder torque and runout procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool. Inspect the shank and collet bore for contamination before seating. Given the miniature diameter, verify runout with a dial indicator before commencing cuts to prevent tool breakage.
