Accupro 12468192 Ball End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12468192 is a single-end ball end mill designed for precision milling of contoured surfaces, slots, and three-dimensional profiles. Built from micrograin solid carbide, it delivers hardness and edge retention well beyond standard high-speed steel tooling. The 1/4 inch diameter cutting head features a 3/4 inch length of cut and a 30-degree right-hand spiral helix that promotes efficient chip evacuation and smooth surface finishes. This tool runs bright and uncoated, making it well suited for non-ferrous metals, plastics, and composite materials where coating adhesion or chemical reaction is a concern. It belongs to the Miniature Series, targeting close-tolerance finish work in small-part machining environments.

The 12468192 fits applications in precision machining shops, tool and die operations, mold-making, and production environments where small-diameter profiling is required. The 1/4 inch shank diameter accepts standard 1/4 inch collet systems. A 2-1/2 inch overall length provides reach for recessed features while keeping deflection manageable at this diameter. Right-hand cutting direction suits conventional CNC and manual milling setups. This is a single-end tool intended for one-pass service life management in high-tolerance workflows.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• Ball end geometry for profiling, contouring, and 3D surface milling
• 30-degree right-hand helix for effective chip evacuation
• Bright/uncoated finish suited for non-ferrous metals, plastics, and composites
• Single-end design with 2-flute configuration for clean cutting in small features
• Miniature Series built for close-tolerance, small-diameter applications

Compatibility

Designed as an OEM-style replacement or direct substitute for miniature series solid carbide ball end mills requiring a 1/4 inch shank and 1/4 inch cutting diameter in standard collet-based milling setups.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully powered down and locked before changing tooling. Seat the 1/4 inch shank fully into a matched collet or end mill holder and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before cutting; excessive runout at this diameter will accelerate edge chipping. Follow applicable shop safety standards for rotating cutting tools.
