Accupro 2500055 Chamfer Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 2500055 is a solid carbide chamfer mill designed for precision chamfering operations on metallic and composite workpieces. The cutter features a 1/2 inch cutter head diameter, a 60-degree included angle, and a single-end configuration with 4 flutes for efficient chip evacuation and a clean edge finish. A TiCN (titanium carbonitride) coating increases surface hardness and reduces friction at the cutting edge, extending tool life in demanding applications. The 1/2 inch shank and 3 inch overall length suit standard collet and end mill holders commonly found in vertical machining centers and manual mills.

This chamfer mill is suited for right-hand cutting operations where deburring, edge-breaking, and chamfering of drilled holes or milled contours are required. It performs well in ferrous and non-ferrous materials including steel, aluminum, and cast iron. Machinists and tool-and-die professionals use this style of cutter on CNC machining centers and manual knee mills for production and prototype work where consistent chamfer geometry is required.

Key Features

• Solid carbide construction for rigidity and dimensional stability at elevated cutting speeds
• TiCN coating improves wear resistance and reduces built-up edge in steel and cast iron
• 60-degree included angle for standard chamfer and countersink geometry
• 4-flute design promotes chip evacuation and surface finish quality
• Right-hand cutting direction compatible with standard spindle rotation
• Single-end configuration with 1/2 inch shank fits common end mill holders and collet chucks

Compatibility

Designed for use in standard 1/2 inch end mill holders, ER collet chucks, and Weldon-style holders on vertical machining centers and manual milling machines requiring right-hand, single-end chamfer tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Inspect the collet or holder for wear and confirm shank seating depth meets the holder manufacturer's minimum engagement recommendation. Do not exceed the cutter manufacturer's recommended speeds and feeds for the workpiece material and coating type.
