Accupro 12176722 Ball End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12176722 is a single-end ball end mill designed for precision milling of contoured surfaces, 3D profiles, and complex geometries in metalworking and machining operations. Built from micrograin solid carbide, it delivers rigidity and wear resistance beyond high-speed steel tooling. The 3/4-inch cutting diameter pairs with a 1-inch length of cut and an AlTiN coating, making it well suited for high-temperature cutting environments including hardened steels, stainless, and cast iron. A 35-degree helix angle promotes efficient chip evacuation and smooth cutting action. This mill is installed and used by machinists and CNC operators in job shops, tool rooms, and production machining environments.

This end mill is suited for CNC milling centers and manual knee mills requiring a 3/4-inch shank toolholder. The 3-inch overall length accommodates standard tool holders without requiring extended-reach setups. The 3-flute geometry balances chip clearance with core strength, making it practical for slotting, profiling, and finishing passes on ferrous and non-ferrous workpieces. The right-hand cutting and right-hand spiral flute direction are standard for conventional CNC milling spindle configurations.

Key Features

• Micrograin solid carbide construction for superior hardness and tool life
• AlTiN coating provides oxidation resistance and performance in high-heat cutting conditions
• 35-degree helix angle for efficient chip evacuation and reduced cutting forces
• 3-flute design balances chip clearance with core rigidity for slotting and finishing
• Right-hand cut and right-hand spiral for standard CNC milling spindle compatibility
• Single-end ball nose geometry for contour milling and 3D profiling

Compatibility

Designed as a standard 3/4-inch shank ball end mill compatible with 3/4-inch collet chucks, end mill holders, and hydraulic toolholders used on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the toolholder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges for chipping before each use, as carbide tooling is brittle and sensitive to impact damage during handling.
