The Dormer Pramet C83 20.0 mm Dovetail Cutter is a precision tool designed for machinists who routinely mill accurate 45° dovetail grooves in a variety of metals. Built around a cobalt-based HSS-E core and finished bright, it delivers dependable performance for fixtures, jigs, and dovetail-mounted components.

• Diameter and Teeth: 20.0 mm diameter with 1 cutting edge (1 tooth) for controlled, clean dovetail cuts.
• Depth of Cut and Overall Length: 5.0 mm depth of cut (DOC) with a 63 mm overall length for stability and reach.
• Shank Type: 12 mm Weldon shank for secure clamping and repeatable alignment.
• Material and Finish: Cobalt-based HSS-E with a bright finish to enhance wear resistance and chip evacuation.
• Standard: DIN 1833 C compliant, ensuring compatibility with standard milling setups and tooling catalogs.
• Geometry: 45° dovetail profile with optimized helix and rake angles for smooth engagement across metals.
• Applications: Ideal for milling dovetail grooves in steel, cast steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys.

The tool’s cobalt-enhanced HSS-E composition supports longer tool life under demanding cuts, while the 63 mm length and Weldon shank provide rigidity and precise positioning. With its specific 45° dovetail geometry, this cutter delivers repeatable groove dimensions and clean edge quality across a range of materials, making it a reliable choice for production environments and precision prototyping alike.
