Accupro 35409 Corner Chamfer End Mill 0.75in 4 Flute

Product Description

The ACCUPRO 35409 is a corner chamfer end mill designed for precision milling operations in metal fabrication and machining environments. Built from powdered metal and coated with TiAlN, it delivers extended tool life and heat resistance at elevated cutting speeds. The 4-flute, right-hand cutting geometry with a 30-degree helix provides smooth chip evacuation and a fine pitch for clean, accurate finishes. At 0.75 inches in diameter with a 3-inch length of cut and a 5.25-inch overall length, this tool suits deep-cavity and profiling work on CNC machining centers and manual mills alike. Centercutting capability allows direct plunge entry without a pre-drilled hole.

The 35409 is suited for use on ferrous metals, hardened steels, and high-temperature alloys where TiAlN coating provides oxidation resistance. Its 0.75-inch shank diameter matches standard ER and end mill holders commonly found in production and job-shop environments. The right-hand flute direction and fine pitch make it appropriate for finishing passes and contour milling on vertical and horizontal machining centers.

Key Features

• TiAlN coating for high heat resistance and extended tool life in ferrous and hardened materials
• Powdered metal substrate for consistent hardness and wear resistance throughout the tool body
• 4-flute, right-hand cut design with 30-degree helix for smooth chip flow and surface finish
• Centercutting geometry allows direct plunge entry without a pilot hole
• Fine pitch flute spacing suited for finishing and semi-finishing operations
• 0.75-inch shank diameter for secure grip in standard end mill and ER-style toolholders

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard 0.75-inch end mill holders, ER collet chucks, and milling machine spindles accepting right-hand tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Verify toolholder runout with a dial indicator before cutting to protect both the tool and workpiece. Follow the machine tool manufacturer guidelines for drawbar torque and holder clamping procedures. Confirm cutting parameters, including speed and feed, against the material being machined before initiating a cut.
