Accupro 12184117 Ball End Mill 0.2031 in 2 Flute Carbide

Product Description

The ACCUPRO 12184117 is a solid carbide ball end mill designed for precision milling operations in a wide range of metalworking and machining applications. With a 0.2031-inch mill diameter and a 0.375-inch length of cut, this single-end tool is built for tight-tolerance profiling, contouring, and slotting. The two-flute geometry and 40-degree helix angle combine to promote chip evacuation and smooth cutting action. An AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, extending tool life in ferrous and hardened material applications. The micrograin carbide substrate adds toughness and wear resistance across demanding cutting conditions.

This ball end mill is suited for use in CNC machining centers and manual milling machines handling die and mold work, contoured surface finishing, and small-feature profiling. The 0.25-inch shank diameter accepts standard collet chucks and end mill holders commonly found in production and toolroom environments. Its stub-length configuration and right-hand cutting direction make it a practical choice for machinists working in tight setups where tool rigidity and runout control are critical.

Key Features

• Solid micrograin carbide construction for superior wear resistance and edge retention
• AlTiN coating provides thermal and oxidation resistance for dry or high-speed cutting
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• 2-flute ball-end geometry suited for contour milling and 3D profiling
• Single-end design with right-hand flute direction for standard CNC setups
• Stub length type for improved rigidity in close-quarters or deep-fixture applications

Compatibility

Designed for use with standard 0.25-inch collet chucks and end mill holders on CNC machining centers and vertical milling machines used in general metalworking and die-mold applications.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder specifications. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Verify runout at the cutting end after chucking, as excessive runout will reduce tool life and surface finish quality. Follow your facility's speeds and feeds guidelines for carbide tooling with AlTiN coating in the applicable workpiece material.
