Promax 135-03230 Chamfer Mill 4 Flute 1/2 Inch Carbide

Product Description

The PROMAX 135-03230 is a solid carbide chamfer mill designed for chamfering, countersinking, and spotting operations on CNC machining centers and manual mills. Built with four flutes and a bright uncoated finish, this tool delivers clean, accurate edge breaks and conical features on a wide range of workpiece materials. The 1/2-inch cutter head diameter and 1/2-inch shank diameter provide a balanced, rigid setup, while the 3-inch overall length suits standard toolholder reach requirements. Right-hand cutting geometry makes it compatible with conventional spindle rotation found on the vast majority of production machines.

This chamfer mill is suited for job shops, production machining environments, and tool rooms where chamfering, spotting, and countersinking are routine operations. The solid carbide construction handles both ferrous and non-ferrous materials at elevated feeds and speeds compared to HSS alternatives. The bright uncoated surface finish is appropriate for applications where coating buildup or lubricant compatibility is a concern, including use with cutting oils and water-soluble coolants.

Key Features

• Solid carbide construction for rigidity and wear resistance in production cutting
• 4-flute design for smooth chip evacuation and improved surface finish on chamfered edges
• Right-hand cutting direction compatible with standard CNC and manual mill spindles
• Bright uncoated finish suitable for a broad range of workpiece materials and coolants
• Performs chamfering, countersinking, and spotting from a single tool
• Non-tapered body for straightforward setup in standard end mill holders and collet chucks

Compatibility

Designed as a direct-fit cutting tool for any machine spindle accepting a 1/2-inch straight shank, including standard ER collet chucks, end mill holders, and milling chucks used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is powered down and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or holder bore and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts to protect both the tool and the workpiece.
