Accupro 33058 Corner Chamfer End Mill 0.4375 in 4 Flute

Product Description

The ACCUPRO 33058 is a corner chamfer end mill designed for milling chamfers and angled edges on ferrous and non-ferrous workpieces. Built from powdered metal with a bright, uncoated finish, it delivers consistent edge geometry across production and job-shop environments. The tool measures 0.4375 inches in diameter with a 1 inch length of cut, a 3/8 inch shank diameter, and a 2-11/16 inch overall length. Four right-hand flutes with a 30-degree helix provide efficient chip evacuation and smooth surface finish. Center-cutting capability allows plunge entry without pre-drilling. Machinists and tool-and-die professionals use this end mill in manual mills, CNC machining centers, and knee mills.

This corner chamfer end mill is suited for light to medium deburring, edge-breaking, and chamfering operations on steel, cast iron, aluminum, and similar materials. The fine pitch and right-hand cutting direction make it appropriate for general-purpose chamfer milling on both flat and contoured surfaces in vertical and horizontal machining setups. It is a practical choice for shops needing a reliable corner chamfer profile without specialty coatings.

Key Features

• 0.4375 inch cutting diameter with 1 inch length of cut for controlled chamfer depth
• Powdered metal construction for consistent hardness and edge retention
• 4 right-hand flutes with 30-degree helix for efficient chip removal
• Center-cutting design allows direct plunge entry
• Bright, uncoated finish suitable for use with or without cutting fluid
• Fine pitch flute spacing reduces chatter on light chamfering passes

Compatibility

Designed as an OEM-style replacement or direct-use corner chamfer end mill for standard 3/8 inch shank tool holders in CNC machining centers, manual vertical mills, and similar machine tool setups.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 3/8 inch shank in a properly sized end mill holder or collet chuck, ensuring adequate clamping depth to prevent runout. Power down and lock out the machine spindle before changing tooling. Verify tool stick-out and holder tightness before initiating any cutting operation.
