Accupro 2500422 Ball End Mill 7/32 in 3 Flute Carbide Ticn

Product Description

The ACCUPRO 2500422 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in ferrous and non-ferrous materials. Built from micrograin solid carbide, it carries a TiCN (Titanium Carbonitride) coating that improves surface hardness and wear resistance compared to uncoated carbide. The cutting diameter is 0.2188 inches (7/32 inches) with a 3/4 inch length of cut and a 2-1/2 inch overall length. Three right-hand spiral flutes at a 35-degree helix angle promote efficient chip evacuation and reduce cutting forces during finish and semi-finish passes. A 1/4 inch shank fits standard end mill holders and collets on CNC machining centers and manual mills.

This end mill is suited for tool and die work, mold making, and precision part machining where tight tolerances and smooth surface finishes are required. The micrograin carbide substrate supports higher speeds and feeds than standard carbide grades, making it appropriate for hardened materials and high-speed machining applications. It is a single-end tool intended for use in machine shops running CNC vertical machining centers, knee mills, or similar equipment requiring small-diameter ball nose tooling.

Key Features

• Micrograin solid carbide substrate for improved wear resistance and edge retention
• TiCN coating increases surface hardness and reduces friction at the cutting edge
• 35-degree helix angle with right-hand spiral flutes for efficient chip evacuation
• Three-flute geometry balances chip clearance with rigidity in small-diameter applications
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent dimensional accuracy
• Shank diameter tolerance of +0.0001 / -0.0004 inches for precise holder fit

Compatibility

Designed as an OEM-style replacement or direct-use ball end mill compatible with standard 1/4 inch end mill holders, ER collet systems, and similar toolholding on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked before loading the end mill into the holder. Verify collet or holder bore size matches the 1/4 inch shank before tightening. Inspect the cutting edges for chips or coating damage before each use, and confirm runout is within acceptable limits after mounting.
