Accupro 12177113 Ball End Mill 0.1875 in 4 Flute Altin

Product Description

The ACCUPRO 12177113 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. With a 0.1875 inch (3/16 inch) mill diameter and a 0.625 inch length of cut, this single-end tool delivers consistent ball-nose profiles for contour milling, slotting, and 3D surface work. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. Four right-hand flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. Micrograin carbide substrate adds toughness and wear resistance for demanding applications.

This ball end mill suits CNC machining centers handling die and mold work, aerospace components, and precision part production. It is appropriate for cutting steel, stainless steel, cast iron, and other hard materials where the AlTiN coating provides a thermal barrier. The 0.1875 inch shank diameter fits standard collets and toolholders commonly found in vertical and horizontal machining centers. Machinists and toolroom operators select this geometry for finish passes and tight-tolerance contour work where ball-nose accuracy is critical.

Key Features

• 0.1875 inch ball nose diameter for precise contour and 3D surface milling
• AlTiN coating for high heat resistance and extended tool life in hard materials
• 4 right-hand spiral flutes with 40-degree helix for efficient chip removal
• Micrograin solid carbide substrate for wear resistance and rigidity
• Single-end design with 0.625 inch length of cut and 2.0 inch overall length
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed as a direct-fit replacement for 3/16 inch shank ball end mill toolholders and collets in standard CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing cuts to protect both the workpiece and the tool.
