Accupro 35389 Corner Chamfer End Mill 1.25in 6 Flute

Product Description

The ACCUPRO 35389 is a corner chamfer end mill designed for milling chamfers and angular profiles on ferrous and non-ferrous materials. Built from powdered metal, this cutter offers improved wear resistance compared to standard high-speed steel. The 35389 measures 1.25 inches in diameter with a 3-inch length of cut and a 5.5-inch overall length. Six flutes provide a fine pitch configuration suited for finishing and semi-finishing passes. A 30-degree helix angle promotes smooth chip evacuation, and the bright uncoated finish makes it well-suited for applications where coating adhesion or heat buildup is not a primary concern. Machinists and tool-and-die professionals install this cutter in CNC machining centers and manual knee mills.

The ACCUPRO 35389 is used in metalworking environments for producing chamfered edges, angular relief cuts, and transitional profiles on workpiece corners. The 1.25-inch diameter and 3-inch length of cut allow access to moderately deep features without requiring extended-reach tooling. Center-cutting geometry enables plunge entry, adding versatility for pocketing and slotting operations when needed. The fine pitch and six-flute count make this end mill a practical choice for light-to-moderate material removal on steel, cast iron, and similar materials in both production shop and maintenance-repair settings.

Key Features

• Powdered metal construction for increased wear resistance over standard HSS
• Six flutes with fine pitch for smoother finish cuts and reduced chatter
• 30-degree helix angle promotes efficient chip evacuation
• Center-cutting design allows direct plunge entry into workpiece
• Bright uncoated finish suitable for general-purpose milling applications
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1.25-inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing the cutter from the tool holder. Ensure the tool holder bore and shank are clean and free of chips before seating the end mill. Follow the machine manufacturer and cutting tool manufacturer guidelines for appropriate speeds, feeds, and depth of cut for the material being machined.
