ZHDG Series

Back to: Dicing Blades

Availability: Product not in stock!

Electroformed hub blades producing high quality substrate dicing


Electroformed bond
Applications: Chip LED board, Various types of semiconductor packages, etc

The ZHDG series developed for dicing various substrates adopts a larger grit size compared to the hub blades for semiconductor wafers. Also, the abundant concentration lineup meets a number of different customer requests.


Product Classification
  • Improved operability thanks to the aluminum base as compared with standard hubless type blades for dicing substrates.
  • Selectable from a lineup with an abundant variety of grit sizes and concentrations.
  • Reduction in resin/metal burring by selecting a low concentration.

To use these DISCO blades and wheels (hereafter precision tooling) safely...
Please read carefully and follow the instructions below to prevent any accidents or injuries:

  • USE a safety cover (nozzle case, cover), equipped as a standard accessory, to avoid injury.
  • DO NOT EXCEED the specified rpm limit indicated on the precision tooling.
  • FOLLOW the instruction manual of the equipment to mount the precision tooling properly.
  • DO NOT DROP OR HIT the precision tooling. This may cause breakage or injury.
  • Always CHECK the precision tooling for chipping or any other damage before starting to use it. DO NOT USE the tooling if there is any damage.
  • READ the operation manual of the cutting/grinding equipment before use.
  • DO NOT USE the precision tooling with modified or customized equipment.
  • DO NOT USE precision tooling that has a different size from the one recommended for your equipment.
  • DO NOT USE the precision tooling for any other purpose than grinding, cutting, or polishing.
  • Always USE water or coolant to prevent precision tooling damage.
