greenteQ SDS-Plus hammer drill bits 4S are made from high-quality special steel with four carbide cutting edges at a 90° angle to each other. In addition, the carbide tip has a centring tip and reinforcement chamfers. This increases service life and prevents catching upon contact with reinforcement in concrete. True four-spiral design achieves optimal removal of cuttings. In addition, this sturdy spiral shape lowers the risk of breakage and reduces vibrations during drilling. The main applications include drilling in concrete, masonry and natural stone – especially for reinforcements. Specially designed for mounting the greenteQ Climate Conformal System in masonry.
Product advantages:
• Long service life due to durable carbide tip
• Optimal cutting transport through a true four-spiral design
• Allows for quicker drilling
• Spiral core optimised for low-vibration drilling and high resistance to breakage
• The force is transmitted directly to the drill point
