Concrete drill SDS-max 20 x 520 211 004 905 Zentro S & R

Bur concrete S & R SDS-max Zentro is used for drilling holes in a perfectly flat concrete, masonry and natural stone.

When drilling holes deeper than 450 mm is necessary for making pre-drilling drill length at a depth of not less than 150 mm, then the drill 450 mm in length, then drills 600 or 900 mm.

Bur SDS-max Zentro has:

• dynamically stable structure, ensuring reduction in vibration during drilling, which greatly improves the efficiency of execution of apertures;
• 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 hole and reduce vibration;
• the heat treated surface with a special polishing to reduce wear and increase the resilience of the drill to the internal voltage during operation.

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