Accupro 12184423 Ball End Mill 0.25 in 3 Flute Carbide

Product Description

The ACCUPRO 12184423 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. With a 0.25-inch diameter, a 3-flute spiral configuration, and a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes on contoured and complex geometry workpieces. The AlTiN coating provides thermal resistance and extended tool life in dry or high-speed cutting applications. At 2 inches overall length with a 0.375-inch length of cut, it is suited for close-tolerance profiling, slotting, and 3D contouring work on CNC machining centers and manual mills.

This ball end mill is used in metalworking and machining environments where accurate radius profiling and die-mold work are required. The micrograin carbide substrate supports hardened material applications and high-speed finishing passes. The single-end, right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations on vertical CNC machining centers. It is commonly installed by machinists and tooling technicians working in job shop, aerospace, automotive, and die-mold production environments.

Key Features

• 0.25-inch mill diameter with 0.375-inch length of cut for precise radius work
• 3-flute spiral design promotes chip evacuation and reduces vibration during cutting
• 40-degree helix angle supports aggressive feed rates and smooth finishes
• AlTiN coating enhances heat resistance and extends tool life in ferrous and hardened materials
• Micrograin solid carbide substrate provides rigidity and wear resistance
• Single-end, right-hand cutting direction fits standard CNC spindle setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 0.25-inch shank diameter collet or tool holder.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 0.25-inch shank fully and concentrically in the collet or end mill holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning cutting operations to prevent premature tool wear or workpiece damage.
