Accupro 12176721 Ball End Mill 0.625 in 3 Flute Carbide

Product Description

The ACCUPRO 12176721 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. The 0.625 inch diameter tool features a 0.75 inch length of cut and a 3 inch overall length, with a matching 0.625 inch shank diameter for direct collet or end mill holder mounting. Three flutes with a 35-degree right-hand helix provide efficient chip evacuation and a smooth cutting action. An AlTiN coating improves thermal resistance and tool life in high-speed and dry cutting applications. Micrograin carbide substrate supports the fine edge geometry required for contour and finish milling passes.

This end mill is suited for CNC machining centers and manual knee mills running ferrous alloys, stainless steel, hardened steels, and similar materials where heat generation and tool wear are primary concerns. The ball nose profile is used for 3D contour milling, die and mold work, radius profiling, and finishing passes on curved or sculptured surfaces. The single-end, right-hand cutting configuration is standard for conventional and climb milling on vertical machining centers.

Key Features

• 0.625 inch mill diameter with micrograin solid carbide substrate for rigidity and edge retention
• AlTiN coating provides high-temperature oxidation resistance for dry and high-speed cutting
• 3-flute geometry balances chip clearance with surface finish quality
• 35-degree right-hand spiral helix promotes smooth cutting action and chip evacuation
• Single-end ball nose profile for 3D contouring, radius profiling, and die and mold finishing
• Mill diameter tolerance of +0.000 to -0.003 inches for consistent fit and repeatability

Compatibility

Designed as a direct-fit solid carbide ball end mill for standard 0.625 inch collets and end mill holders on CNC vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Confirm the holder bore and collet size match the 0.625 inch shank before seating the tool. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Follow machine tool builder guidelines for tool overhang, runout inspection, and torque specifications when tightening the holder.
