Accupro 12464273 Ball End Mill 0.105 in 4 Flute Altin Carbide

Product Description

The ACCUPRO 12464273 is a solid carbide ball end mill designed for precision milling operations requiring tight tolerances and fine detail work. Built from micrograin carbide stock, it measures 0.105 inches in cutting diameter with a 0.315-inch length of cut and a 1/8-inch shank diameter. The AlTiN coating provides thermal resistance and extended tool life in harder workpiece materials. With 4 spiral flutes and a 30-degree helix angle, this single-end mill delivers efficient chip evacuation and smooth cutting action. Overall length is 1.5 inches. It is sized for the miniature series and targets applications where small-diameter, high-precision milling is required.

This end mill is suited for CNC machining centers and manual mills running ferrous and non-ferrous materials where small-feature contouring, slotting, or profiling is the primary task. The miniature form factor makes it a go-to choice for tool and die work, mold cavity detail passes, and precision component machining in aerospace, medical, and general metalworking shops. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating extends tool life and reduces heat buildup at higher cutting speeds
• 4-flute spiral geometry with 30-degree helix for smooth chip flow and surface finish
• Ball nose profile enables contoured surface milling and 3D profiling passes
• Single-end design with 1/8-inch shank for standard collet and end mill holder compatibility
• Mill diameter tolerance of plus 0.0000 and minus 0.0010 inches ensures dimensional accuracy

Compatibility

Designed for use in standard 1/8-inch collets and end mill holders on CNC machining centers or manual mills with right-hand spindle rotation. No specific compatible machine models were named in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or holder and torque to the holder manufacturer's specification. Verify runout with an indicator before beginning a production run, as small-diameter carbide tools are sensitive to excessive runout and can fracture under lateral load.
