Accupro 14556467 Ball End Mill 0.125 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14556467 is a single-end ball end mill designed for precision milling operations in ferrous and hardened materials. Built from micrograin solid carbide and coated with AlTiN+, this tool handles high-temperature cutting environments where standard coatings fall short. The 0.1250 inch diameter with a matching 0.1250 inch shank fits standard collet chucks and toolholders in that size range. The 4-flute, right-hand spiral configuration at a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. With a 0.5000 inch length of cut and 1.5000 inch overall length, this mill is sized for standard-reach applications in CNC machining centers and manual mills.

This end mill is suited for die and mold work, contour milling, and finishing passes on hardened steel, stainless steel, cast iron, and high-temperature alloys. The AlTiN+ coating provides elevated oxidation resistance and hardness at the cutting edge, making it a practical choice for dry or minimal-lubrication machining. CNC machinists and tool-and-die professionals working with tight-tolerance features and complex profiles will find this a capable option at the 1/8 inch diameter class. The standard length type and medium helix style make it a general-purpose fit for production and job-shop environments alike.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating delivers high oxidation resistance and extended tool life in dry or low-coolant conditions
• 40-degree right-hand helix promotes efficient chip evacuation and reduces cutting forces
• 4-flute spiral design supports smooth surface finishes on finishing and semi-finishing passes
• Single-end configuration with right-hand cutting direction for standard CNC and manual mill setups
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent fit and dimensional accuracy

Compatibility

Designed as a standard single-end ball end mill with a 0.1250 inch shank diameter, compatible with collet chucks, end mill holders, and toolholders sized for 1/8 inch shank tooling on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended depth in the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use, as micrograin carbide tools can fracture if run at incorrect feeds and speeds for the workpiece material.
