Professional for 9mm x 350mm Rotary Hammer

Dimensions: Diameter: 9 mm, Overall Length: 350 mm, Spiral Length: 267 mm. High-Quality Drill Bit: The drill bits are made of welded and hardened tungsten carbide. Thanks to the use of cemented carbide and an optimized high-temperature cooling process, the drill bit becomes more wear-resistant and thus improves its efficiency. More Efficient Drilling: The innovative quadruple screw of the grinder ensures rapid extraction of rock drilling dust and prevents clogging of the drill bit channel. This not only increases drilling speed but also improves the accuracy and lifespan of the concrete drill bit. The 4-blade X-shaped carbide design allows for faster cutting and prevents reinforced concrete from tipping over. Versatility: The tungsten carbide plates have grooves and notches to ensure smooth operation. Suitable not only for drilling holes in masonry, but also in other materials such as concrete, natural stone, or limestone and sand brick with this drill. Compatibility: This drill bit is compatible with all impact drills with a system.
