Accupro 33078 Corner Chamfer End Mill 0.625 in 4 Flute Tialn

Product Description

The ACCUPRO 33078 is a corner chamfer end mill designed for precision milling operations in metalworking and machining applications. Built from powdered metal and coated with TiAlN, it delivers wear resistance and heat tolerance in demanding cutting conditions. The 33078 measures 0.625 inches in diameter with a 1.625-inch length of cut and a 3.75-inch overall length. Its 4-flute, right-hand cutting geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The centercutting design allows plunge entry, adding flexibility for slotting, profiling, and ramping operations. Machinists and CNC operators working in tool and die, production milling, and general metalworking will find this end mill suited to finishing and semi-finishing passes.

This end mill is intended for use on CNC machining centers and manual knee mills handling ferrous metals, stainless steels, and high-temperature alloys where TiAlN coatings perform best. The fine pitch and right-hand flute direction make it appropriate for general-purpose contouring and profiling work in production and job shop environments. The 5/8-inch shank diameter fits standard ER and end mill holders commonly used in these operations.

Key Features

• TiAlN coating for elevated heat and wear resistance in ferrous and hard-material cutting
• Powdered metal substrate provides consistent hardness and fine grain structure throughout the tool
• 4-flute, right-hand cutting design with 30-degree helix for smooth finish and chip flow
• Centercutting capability allows direct plunge entry without a pre-drilled pilot hole
• Fine pitch geometry suited to finishing and semi-finishing passes
• 5/8-inch shank diameter fits standard end mill and collet holders

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills accepting a 5/8-inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to confirm proper seating in the holder. Follow machine tool manufacturer torque specifications for set screws or collet nuts.
