Accupro 2500255 Chamfer Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 2500255 is a solid carbide chamfer mill designed for precision chamfering operations on metallic workpieces. With a 3/4-inch cutter head diameter, 4 flutes, and a 60-degree included angle, this single-end tool delivers clean, consistent chamfer profiles at high feed rates. The TiCN (Titanium Carbonitride) coating improves surface hardness and wear resistance compared to uncoated carbide, making it well suited for ferrous and non-ferrous materials. Right-hand cutting geometry and a 3/4-inch shank diameter allow direct mounting in standard end mill holders or collet chucks. The overall length of 4 inches provides adequate reach for most machining center setups.

This chamfer mill is used in CNC machining centers and manual milling applications where precise edge preparation is required. Typical applications include deburring drilled holes, preparing weld joints, breaking sharp edges on machined parts, and generating angled features on steel, aluminum, cast iron, and similar materials. It is appropriate for job shops, production machining, and maintenance repair operations where a durable, ready-to-run chamfering tool is needed.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding cuts
• TiCN coating increases surface hardness and reduces wear on ferrous and non-ferrous materials
• 60-degree included angle for standard chamfer and deburring geometry
• 4-flute design balances chip evacuation with surface finish quality
• Right-hand cutting direction compatible with conventional CNC spindle rotation
• 3/4-inch shank diameter fits standard end mill holders and collet chuck systems

Compatibility

Designed as an OEM-style solid carbide chamfer mill for use in CNC machining centers and manual mills accepting 3/4-inch shank tooling with standard end mill holders or ER collet systems.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before loading or removing the tool. Seat the shank fully into the holder and torque retention screws to the holder manufacturer's specifications. Verify runout with a dial indicator before engaging the workpiece, as excessive runout will accelerate wear on carbide tooling.
