Accupro 95168566 Corner Chamfer End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 95168566 is a solid carbide corner chamfer end mill designed for precision milling of chamfered edges and corner breaks on ferrous and non-ferrous workpieces. It features a 3/4 inch diameter, a 2.25 inch length of cut, and a 45-degree chamfer angle with a 0.0200 inch chamfer width. The micrograin solid carbide construction is paired with an AlTiN coating for extended tool life at elevated cutting temperatures. Four spiral flutes with a variable helix and right-hand cutting direction promote efficient chip evacuation and reduced chatter. This is a single-end, centercutting tool suitable for plunge entry. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill is suited for ferrous metals, hardened steels, and high-temperature alloys where AlTiN coating performance is most effective. The long-length configuration with a 5 inch overall length allows reach into deeper setups without sacrificing rigidity. The 3/4 inch shank diameter provides solid retention in standard ER collet chucks, Weldon-style holders, and hydraulic chucks. Typical applications include chamfering drilled holes, breaking sharp corners on milled profiles, and deburring operations on CNC machining centers or manual knee mills.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating extends tool life in dry and semi-dry cutting of ferrous materials
• Variable helix design reduces harmonic vibration and chatter during cut
• 45-degree chamfer angle with 0.0200 inch chamfer width for consistent edge breaks
• Centercutting capability allows direct plunge entry into the workpiece
• Long-length profile at 5 inches OAL extends reach for deeper setups

Compatibility

Designed for use in standard 3/4 inch toolholders including ER collet chucks and Weldon-style end mill holders on CNC machining centers and manual milling machines. No specific machine model compatibility was stated by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before loading or unloading the tool. Verify toolholder runout with a dial indicator before production cutting to stay within the stated diameter tolerance of +0.000 to -0.002 inches. Follow the toolholder manufacturer torque specifications when securing set screws or collet nuts.
