Accupro 14788657 Ball End Mill 0.5 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788657 is a 3-flute solid carbide ball end mill designed for milling curved surfaces, contoured profiles, and 3D finishing passes on hard and abrasive workpiece materials. It carries an AlTiN+ coating, which improves heat resistance and extends tool life in dry or semi-dry cutting conditions at elevated speeds. The 0.5 inch cutting diameter pairs with a 2 inch length of cut, making it well suited for moderate-depth pocketing and profiling operations. The cylindrical shank measures 0.5 inches in diameter and the overall tool length is 4 inches. This end mill is installed and used by machinists in CNC milling centers across job shops, tool rooms, and production environments.

This end mill is intended for use on CNC vertical and horizontal machining centers where ball-nose geometry is required for sculpted or radiused features. The medium flute type balances chip evacuation with edge strength, making it appropriate for steels, hardened alloys, and non-ferrous materials where a consistent surface finish is the objective. The 2 inch length of cut provides sufficient reach for most mold, die, and general-purpose contouring work without sacrificing rigidity at the 0.5 inch diameter.

Key Features

• AlTiN+ coating provides high-temperature oxidation resistance for extended tool life in ferrous and hardened materials
• 3-flute design balances material removal rate with chip clearance on contoured cuts
• Solid carbide construction delivers rigidity and wear resistance superior to HSS at elevated cutting speeds
• Medium flute type suited for both roughing passes and semi-finish profiling
• Cylindrical shank compatible with standard ER collets and end mill holders
• No chipbreaker geometry keeps the cutting edge clean for smooth surface finishes on finishing passes

Compatibility

Designed as a standard-shank ball end mill for use in CNC milling machines accepting a 0.5 inch cylindrical shank via ER collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Verify collet or holder bore size matches the 0.5 inch shank diameter before tightening. Confirm tool projection and stick-out against the programmed depth of cut to avoid deflection or chatter during operation.
