## Long description

 Working length: 150 mm
 Compatible materials: concrete, brick, stone, aerated concrete
 Intended drill types: hammer drills and rotary-percussion drills
 Pack quantity: 1 piece
How to use
Select an appropriate hammer or rotary-percussion drill and secure the Dedra WP0821 masonry drill bit in the chuck according to the drill manufacturer's instructions. Mark the drilling point and, if necessary, start with a low speed to position the tip. Use hammer mode for dense masonry such as concrete and stone; for softer aerated concrete, a rotary-percussion or rotary mode with moderate speed may be sufficient. Apply steady forward pressure without forcing the bit, periodically withdraw to clear dust and prevent overheating, and verify hole depth against the required anchor or dowel length.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves, ear protection and a dust mask) and secure workpieces when drilling. For prolonged drilling in hard materials, allow the bit to clear debris frequently. Replace the bit if tip wear or reduced drilling performance is observed to maintain clean, accurate holes.
