Accupro 2500040 Chamfer Mill 1/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 2500040 is a solid carbide chamfer mill designed for precision chamfering operations on metalworking and machining applications. Built with four flutes and a 60-degree included angle, it cuts a consistent, clean chamfer edge in a single pass. The 1/4 inch cutter head and 1/4 inch shank diameter make it compatible with standard collet toolholding setups. The bright, uncoated finish keeps the carbide substrate exposed for maximum hardness and edge retention in light-to-moderate cutting conditions. At 2.5 inches overall length, the tool fits a wide range of vertical and horizontal machining center spindles without excessive overhang.

This chamfer mill is suited for deburring, edge-breaking, and countersinking on ferrous and non-ferrous materials in job shop and production environments. Its right-hand cutting direction and single-end geometry make it a straightforward drop-in for standard CNC machining center operations. Machinists and toolmakers working on close-tolerance parts will find the 60-degree angle useful for thread lead-in chamfers and part preparation before assembly. The compact shank diameter targets smaller spindle setups and high-speed machining environments where tool mass matters.

Key Features

• Solid carbide construction for high rigidity and edge retention
• 60-degree included angle for standard chamfering and thread lead-in applications
• Four-flute design improves chip evacuation and surface finish quality
• Bright, uncoated finish suitable for aluminum, brass, and light steel applications
• Right-hand cutting direction compatible with conventional CNC spindle rotation
• 1/4 inch shank diameter fits standard ER collet and end mill holder setups

Compatibility

Designed as an OEM-style solid carbide chamfer mill suitable for standard 1/4 inch collet toolholding systems on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or end mill holder and torque the drawbar or nut to the machine manufacturer's specification — do not use values not specified by your machine OEM. Verify runout with a dial indicator before cutting to protect both the tool and the workpiece.
