Electroplated Diamond Grinding Wheel (11A2)— Bowl Shape | Carbide End Mill & Flute Grinding
The ED-11A2 is an 11A2 bowl-profile electroplated diamond grinding wheel designed for gashing and flute grinding of tungsten carbide end mills, drill points, and rotary tools.
The electroplated bond delivers sharp, aggressive cutting action with no dressing required. The bowl geometry provides clearance for adjacent flutes during grinding, making it well-suited for dedicated knife grinders and CNC tool grinding machines.
