Accupro 33057 Corner Chamfer End Mill 0.375 in 4 Flute

Product Description

The ACCUPRO 33057 is a corner chamfer end mill designed for milling chamfered edges and angled profiles on ferrous and non-ferrous workpieces. Built from powdered metal with a bright, uncoated finish, it delivers consistent cutting performance in general machining applications. The tool measures 0.375 inches in diameter with a 0.75-inch length of cut and a 2.5-inch overall length. A 3/8-inch shank diameter suits standard collet and end mill holders. The 4-flute, right-hand cutting geometry with a 30-degree helix promotes efficient chip evacuation and a fine pitch for smooth surface finishes. Centercutting capability allows plunge entry directly into the workpiece.

This end mill is suited for machining operations on CNC machining centers and manual knee mills where corner chamfering or deburring is required. It handles chamfer milling on steel, cast iron, aluminum, and similar materials in job shop, tool room, and production environments. The right-hand flute direction and fine pitch make it appropriate for moderate feed rates and precise edge-breaking work. Machinists and toolroom operators working in light to medium-duty applications will find the geometry straightforward to apply.

Key Features

• Corner chamfer geometry for angled edge milling and chamfering operations
• Powdered metal construction for consistent hardness and wear resistance
• 4-flute, right-hand cut with 30-degree helix for smooth chip flow
• Centercutting design allows direct plunge entry
• Bright, uncoated finish suitable for general-purpose machining
• Fine pitch for improved surface finish on chamfered edges

Compatibility

Designed as a standard 3/8-inch shank corner chamfer end mill compatible with collet chucks, end mill holders, and other toolholding systems accepting a 3/8-inch straight shank on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists and toolroom operators 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 to the manufacturer-recommended engagement depth and torque the retention system per the toolholder specification. Verify runout with a dial indicator before cutting to maximize tool life and edge quality.
