Accupro 33059 Corner Chamfer End Mill 0.5 in 4 Flute

Product Description

The ACCUPRO 33059 is a corner chamfer end mill designed for milling chamfers and edge-breaking operations on a wide range of ferrous and non-ferrous workpiece materials. Built from powdered metal, it delivers a balance of toughness and wear resistance suited for general-purpose machining. The cutter runs a 0.5-inch diameter with a 1.25-inch length of cut and a 3.25-inch overall length. Four flutes with a 30-degree helix angle and a fine pitch configuration support efficient chip evacuation and a stable cut. The bright, uncoated finish makes it straightforward to inspect for wear. This is a centercutting tool, allowing plunge entry into the workpiece when the operation calls for it.

The 33059 is used in manual mills, CNC machining centers, and knee mills where chamfering, deburring, and edge preparation are part of the workflow. It is commonly applied in job shops, maintenance machining environments, and production cells handling steel, cast iron, aluminum, and similar materials. The right-hand cutting direction and right-hand flute direction are standard for conventional spindle setups. The 0.5-inch shank diameter fits standard collets and end mill holders found in most shops.

Key Features

• Corner chamfer geometry for chamfering and edge-breaking operations
• Powdered metal construction for toughness and wear resistance in general-purpose use
• 4-flute, fine-pitch design supports stable cutting and efficient chip removal
• 30-degree helix angle balances cutting forces across the flute length
• Centercutting capability allows direct plunge entry
• Bright, uncoated finish for easy wear inspection and broad material compatibility

Compatibility

Designed as a standard 0.5-inch shank corner chamfer end mill compatible with collet chucks, end mill holders, and milling adaptors sized for 0.5-inch tooling on manual and CNC milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder and torque the retention hardware per the toolholder manufacturer's specifications. Inspect the cutting edges and shank for damage before each use, and confirm runout is within acceptable limits before beginning a cut.
