Vitrified Bond Diamond Grinding Wheel (11A2)— Bowl Profile | PCD, PCBN & Carbide Tool Grinding

The VD-11A2 is an 11A2 bowl-profile vitrified bond diamond grinding wheel designed for precision grinding of PCD, PCBN, ceramic, and tungsten carbide cutting tools.

The bowl geometry with 45° inner face provides clearance for adjacent tool features during grinding, making it particularly well-suited for PCD insert edge preparation, PCBN tool sharpening, and CNC tool grinder applications. The vitrified bond delivers free-cutting action, excellent form retention, and easy dressing.

Applications

Application Recommended Grit Notes
PCD insert edge grinding W10–W28 (~400#–1200#) 45° bowl face contacts PCD cutting edge; inner geometry clears insert body
PCBN tool sharpening W20–W40 (~320#–600#) Higher MRR than 6A2 cup; suitable for rough and semi-finish passes
Natural diamond & MCD tool grinding W5–W10 (~1200#–2500#) Ultra-fine grit for mirror-edge preparation on monocrystalline diamond tools
Carbide tool face grinding W20–W40 (~320#–600#) Bowl profile suits CNC tool grinder face grinding programs
Ceramic & CVD tool grinding W10–W20 (~600#–1200#) Vitrified bond minimises heat transfer to thermally sensitive CVD coatings
