Accupro 2500139 Chamfer Mill 1/4 in 4 Flute Solid Carbide Ticn

Product Description

The ACCUPRO 2500139 is a solid carbide chamfer mill designed for precise chamfering operations on metallic and composite workpiece materials. With a 1/4 inch cutter head diameter and 4 flutes, it delivers clean, consistent chamfers in a single pass. The 120-degree included angle makes it well suited for edge breaking, deburring, and countersinking applications. A titanium carbonitride (TiCN) coating reduces friction and improves wear resistance, extending tool life in production environments. The right-hand cutting direction and 1/4 inch shank diameter allow straightforward mounting in standard collet chucks and milling tool holders. Machinists and CNC operators working in job shops, toolrooms, or production cells will find this a reliable, direct-fit option.

This chamfer mill is intended for use in vertical or horizontal milling machines, machining centers, and CNC routers where controlled chamfering, deburring, or edge preparation is required. The solid carbide construction allows operation at higher speeds and feeds compared to high-speed steel alternatives, making it appropriate for ferrous metals, aluminum alloys, and engineered plastics. The 2-1/2 inch overall length provides sufficient reach for most standard workholding setups without sacrificing rigidity.

Key Features

• Solid carbide construction for rigidity and extended tool life at elevated cutting speeds
• TiCN coating reduces tool wear and heat buildup during continuous cutting operations
• 4 flutes provide improved chip evacuation and a finer surface finish on chamfered edges
• 120-degree included angle covers common chamfer and countersink geometries
• Right-hand cutting direction compatible with standard spindle rotation on most milling platforms
• 1/4 inch shank diameter fits ER collets, set-screw holders, and shrink-fit tooling of matching bore

Compatibility

Designed as an OEM-style replacement or direct-fit chamfer mill for milling machines and machining centers accepting a 1/4 inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle drive before mounting or removing the tool. Seat the shank fully into the collet or tool holder to the recommended gauge-line depth before tightening to ensure concentricity and prevent pullout. Inspect the cutting edges and TiCN coating for chips or damage before each use, and replace the tool if edge integrity is compromised.
