Accupro 33066 Corner Chamfer End Mill 0.25in 3 Flute Tialn

Product Description

The ACCUPRO 33066 is a corner chamfer end mill designed for precision milling operations in metal fabrication and machining environments. Built from powdered metal and finished with a TiAlN coating, this tool handles demanding cutting tasks while maintaining edge integrity at elevated temperatures. It features a 0.25-inch cutting diameter, 0.625-inch length of cut, and a 2-7/16-inch overall length. The 3-flute, right-hand cutting geometry with a 30-degree helix delivers efficient chip evacuation and a smooth finish. Centercutting capability allows plunge entry, giving machinists added flexibility in toolpath strategy.

This end mill is suited for use in CNC machining centers and manual mills working with ferrous and non-ferrous metals. The fine pitch, right-hand flute direction, and TiAlN coating make it appropriate for high-speed finishing and chamfering passes on hardened or abrasive materials. The 3/8-inch shank diameter fits standard collet and end mill holder configurations commonly found in shop and production environments.

Key Features

• TiAlN coating improves heat resistance and extends tool life in high-speed cuts
• Powdered metal substrate provides consistent hardness and wear resistance
• Centercutting design allows direct plunge entry without pre-drilling
• 30-degree helix angle promotes smooth chip flow and reduced chatter
• Right-hand cut and right-hand flute direction for standard spindle operation
• Fine pitch geometry suited for finishing and chamfering passes

Compatibility

Designed as an OEM-style replacement or direct-use corner chamfer end mill for standard 3/8-inch collets and end mill holders used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut.
