Accupro 95168721 Ball End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 95168721 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. The 3/4-inch diameter cutting head features four flutes with a right-hand spiral flute direction and a variable helix geometry that helps reduce chatter and improve chip evacuation. An AlTiN (aluminum titanium nitride) coating provides elevated heat and wear resistance, making this tool well-suited for high-speed cutting in ferrous metals and hardened materials. Overall length is 3 inches with a 3/4-inch shank diameter, keeping the tool rigid and minimizing deflection under load.

This ball end mill is used in CNC machining centers and manual knee mills for contouring, profiling, slotting, and 3D surface finishing. The single-end configuration and 1-inch length of cut make it appropriate for medium-depth passes in mold and die work, aerospace components, and general precision part production. It is installed and operated by machinists and CNC programmers working with ferrous alloys, stainless steel, titanium, and similar materials where the AlTiN coating delivers measurable tool life advantages over uncoated carbide.

Key Features

• 3/4-inch mill diameter with a tight tolerance of +0.000 / -0.002 inches for accurate finished dimensions
• Four-flute, right-hand spiral geometry with variable helix to reduce vibration and improve surface finish
• AlTiN coating for high-temperature wear resistance in ferrous and hardened-material cutting
• Solid carbide construction, material grade C2, for rigidity and long tool life
• Single-end design with 1-inch length of cut and 3-inch overall length
• Shank diameter tolerance of +0.0001 / -0.0004 inches for consistent tool-holder fit

Compatibility

Designed for use in standard CNC machining centers and manual mills accepting a 3/4-inch straight shank via ER collet chucks, end mill holders, or hydraulic chucks. No specific OEM system compatibility was stated in the product data.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC programmer. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from its holder. Verify the tool-holder bore and collet are clean and free of debris before seating the shank to maintain the specified shank-diameter tolerance. Follow machine manufacturer guidelines for runout inspection and appropriate cutting parameters for the workpiece material and coating type.
