Accupro 12184324 Ball End Mill 1 in 3 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12184324 is a single-end ball end mill designed for precision milling operations in ferrous and hardened materials. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for demanding cuts. The cutting diameter measures 1 inch, with a 1.75-inch length of cut and a 40-degree helix angle that promotes chip evacuation and reduces cutting forces. An AlTiN coating adds thermal hardness, extending tool life in high-speed and dry-machining environments. This end mill is a standard tool for machinists running CNC mills and machining centers where consistent surface finish and dimensional accuracy are critical.

This ball end mill is suited for contour milling, profiling, and 3D surfacing operations in machine shops and production environments. The 1-inch shank diameter provides a secure grip in standard end mill holders, collet chucks, and hydraulic toolholders. The 40-degree right-hand helix with right-hand cutting direction makes it appropriate for conventional and climb milling on steel, stainless steel, cast iron, and similar materials. The single-end configuration is standard for toolroom and production CNC work where one active cutting end is the norm.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smoother cutting action
• 3-flute design balances chip clearance and cutting edge strength for medium-to-heavy material removal
• Right-hand cut and right-hand flute direction — compatible with standard CNC spindle rotation
• Single-end configuration with a 1-inch shank for direct fit into standard toolholders

Compatibility

Designed as a direct-fit replacement or standard toolroom addition for CNC machining centers and manual mills accepting 1-inch shank end mill holders or collet systems. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or placed in an E-stop state before changing tooling. Seat the shank to the full recommended grip length in the holder — a minimum of 2.5 times the shank diameter is a common industry guideline — and torque the set screw or collet nut to the toolholder manufacturer's specification. Inspect the cutting edges for chips or coating damage before use, as carbide tools are brittle and can be damaged by improper handling or storage.
