Dos & Don'ts when using diamond blades

Using a diamond blade can be an inherently hazardous process, so here are our do's and don'ts to keep the risk of injury to an absolutely minimum. 

Initially, it is strongly recommended NOT to use abrasive tools lacking the oSa label or the EN13236 compliancy.

DOs

DIAMOND BLADES

ARE SAFE IF USED

CORRECTLY

  • Read the safety instructions provided by the abrasives and equipment supplier
  • Store diamond blades in dry, frost-free conditions, avoid large temperature variations
  • Ensure that the product is suitable for its purpose
  • Handle, store and transport products with care
  • Disconnect the power to the machine before fitting the diamond blade
  • Examine all products before mounting and periodically during blade use for possible defects or damage (core flatness, fatigue cracks, undercutting, arbor damage…)
  • Check that correct mounting devices are used and that they are clean, undistorted and free from burrs
  • Ensure that work rests are properly adjusted and secure
  • Always use a correctly designed and adjusted guard (on the blade and belts)
  • Ensure that the workpiece is secure
  • Wear appropriate personal protective equipment at all times
  • Avoid clogging and uneven wear to ensure that the product is working efficiently
  • Ensure accordance between product direction arrow / machine rotation
  • Ensure that all machines using abrasives meet the requirements of the current european machinery directives-CE
  • Be aware of the hazards likely during the use of abrasives and observe the recommended precautions to be taken:
    • Bodily contact with the abrasive product at operating speed
    • Injury resulting from product breakage during use
    • Grinding debris, sparks, fumes and dust generated by the grinding process
    • Noise
    • Vibration

 


DON'Ts

DIAMOND BLADES ARE DANGEROUS IF ABUSED

  • Allow untrained people to use abrasives
  • Use a product that is damaged or one which has been dropped
  • Use a product if it cannot be properly identified
  • Use a machine that is not in good working order or one with defective parts
  • Force the abrasive onto the mounting device or modify the size of the mounting hole
  • Exceed the maximum operating speed marked on the product
  • Apply shock or excessive force to the product or let it overheat
  • Use mounting flanges which are not clean and flat
  • Tighten the mounting device excessively
  • Start the machine until the guard is in place and fastened securely
  • Continue to use a product if vibration occurs, true or replace it
  • Grind on the part of the product which is not designed for the operation
  • Start the machine with the workpiece in contact with the abrasive product
  • Grind material for which the product is not designed
  • Stop the abrasive by applying pressure to its surface, let it stop naturally
  • Exceed permissible rotation speeds: refer to values engraved on product
  • Use blades with missing segments or core cracks
  • Use dry products marked for wet use
  • Wear loose clothing, ties and jewellery
  • Use abrasive products near flammable materials

 

 


ALWAYS

  • Wear eye protection EN166B
  • Wear gloves EN 388 cat.2
  • Wear hearing protection EN352
  • Wear a respirator EN149
  • Read the instructions
  • Not to be used for side grinding

NEVER EXCEED  the maximum operating speeds:

  • Handheld blades diam < or = to 230mm : 80 m/s
  • Handheld blades diam > to 230 mm: 100 m/s
  • Others: 63 m/s
