Concrete drill SDS-max 45 x 920 211 004 933 Zentro S & R

Bur concrete S & R SDS-max Zentro used to drill a perfectly smooth holes in concrete, masonry and natural stone.

When drilling holes deeper than 450 mm is necessary to make preliminary . pilot drilling drill shorter length to a depth of at least 150 mm, then the drill 450 mm in length, then drills 600 or 900 mm

Bur SDS-max Zentro has:

• dynamically stable structure, ensuring vibration reduction during drilling, which greatly improves the efficiency of execution of holes;
• Whole tipped with four cutting edges and patented chamfers for perfectly smooth holes;
• patented multichannel KVS-helix greatly increases drilling efficiency due to rapid removal of the slag from the opening and reducing vibration;
• the heat treated surface with a special polishing to reduce wear and increase resistance STI drill to the internal voltage during operation.

  Bur concrete S & R SDS-max Zentro for perforating from 5 kg to the type of cartridge SDS-max or dvuhpazovym.
