Accupro 12177302 Ball End Mill 0.0787 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12177302 is a solid carbide ball end mill designed for high-precision milling operations in ferrous and non-ferrous materials. With a 0.0787-inch (2 mm) cutting diameter and a 2-flute geometry, this tool produces accurate ball-end profiles in confined areas where larger tooling cannot reach. The AlTiN coating provides oxidation resistance and heat hardness retention, extending tool life in abrasive or high-temperature cutting conditions. The micrograin carbide substrate adds toughness and edge retention. This end mill is installed by machinists and CNC operators working in precision manufacturing, tool-and-die, mold making, and aerospace component production.

This end mill is suited for applications requiring tight-tolerance profiling, contouring, and slotting at small diameters. The extended-reach design with a 1.90 mm neck diameter and 15 mm reach length allows access to deep pockets and stepped features without tool interference. The 6 mm shank diameter fits standard collet chucks and shrink-fit holders commonly found on CNC machining centers. It is a single-end tool with right-hand cut and right-hand flute direction, appropriate for conventional CNC milling setups.

Key Features

• 0.0787-inch (2 mm) ball end cutting diameter for small-feature precision milling
• Solid micrograin carbide construction for edge retention and rigidity
• AlTiN coating for high-temperature and abrasion resistance
• 30-degree helix angle for smooth chip evacuation and reduced cutting forces
• Extended-reach geometry with 1.90 mm neck diameter and 15 mm reach length
• 6 mm shank diameter compatible with standard CNC collet and shrink-fit toolholders

Compatibility

Designed for use with standard CNC machining centers accepting a 6 mm shank diameter via collet chuck, shrink-fit, or hydraulic toolholder systems.

Installation Notes

This tool is installed by qualified machinists or CNC setup technicians. Always power down and lock out the spindle before inserting or removing tooling. Verify runout with a dial indicator after seating in the holder, as runout is especially critical at sub-3 mm diameters. Follow the toolholder manufacturer torque specifications for collet nut tightening to avoid shank damage or pullout.
