Accupro 2500044 Chamfer Mill 1/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 2500044 is a solid carbide chamfer mill designed for precision chamfering operations on a wide range of workpiece materials. It features a 1/4 inch cutter head diameter, four flutes, and a 120-degree included angle that produces clean, consistent chamfers in a single pass. The bright/uncoated finish is suited for general-purpose cutting where coating-related heat buildup is not a primary concern. With a right-hand cutting direction and a 2.5 inch overall length, this tool mounts in standard 1/4 inch collets or end mill holders. Machinists and tool-and-die professionals use this mill in CNC machining centers and manual knee mills for edge-breaking and chamfering tasks.

This chamfer mill is used in metalworking, fabrication, and toolroom environments where accurate edge preparation is required. Typical applications include deburring drilled hole entries, chamfering bolt-hole patterns, and preparing mating surfaces for assembly. It is well suited for use on aluminum, steel, and similar machinable materials in both production and job-shop settings. The solid carbide construction maintains cutting-edge integrity at higher spindle speeds compared to high-speed steel alternatives, making it a common choice on CNC machining centers running tight tolerances.

Key Features

• Solid carbide construction for rigidity and extended edge life at elevated speeds
• 120-degree included angle for standard chamfer and edge-break geometry
• Four flutes provide a balance of chip clearance and surface finish quality
• Bright/uncoated finish suitable for general-purpose chamfering applications
• Right-hand cutting direction compatible with conventional spindle rotation
• 1/4 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as a direct-fit replacement for 1/4 inch shank chamfer mills used in CNC machining centers, manual mills, and drill presses equipped with compatible collet or end mill holder tooling.

Installation Notes

A licensed machinist or qualified toolroom professional should install and operate this tool. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the holder. Secure the shank fully within the collet or holder to the manufacturer-specified engagement depth before running the spindle. Verify spindle speed and feed rate are appropriate for the workpiece material before beginning the cut.
