Diamond Blade Data

How deep will my diamond blade cut too? What is the maximum speed I can run this blade at? These are all important questions blade users need to know. Unite Diamond Tools have produced these tables to answer all these questions for you. Just remember:

  • These cutting depths are approximate, and cutting depth will vary due to flange/collar size or if your tool components (motor guard etc) interfere with the cut.
  • Always read your tools operation manual before use to make sure the blades suits the maximum safe speed of your tool.
  • Wear correct PPE (personal protective equipment)
  • Use the tools and blade only in a safe manner as described in the operation manual.

HS - high speed diamond blades

* The general optimal range for cutting masonry & concrete is +10%, whereas for dense hard materials like tile, stone etc, 10-25% has to be deducted from these RPMs to reach optimal performance speed. Speeds are based on tools being operated with load, which cause blade speeds to slow.

** This speed is the maximum safe speed at which the blade can be used. Ensure your tool is rated lower than the maximum safe speed of the tool.
