Description
Four symmetrical 90° cutting edges guarantee circular drill holes for optimum dowel installation
4-spiral helix geometry with large-volume helix for optimal drill dust transport
Centring point for easy, precise spot drilling
Welded-on, one-piece carbide element for Ø 5-10 mm. The resulting larger spiral entry channel ensures faster drilling progress. More carbide for longer service life, especially of the drill point.
4 breaker points for higher drilling speed
Enlarged reinforcement chamfers for longer service life in case of reinforcement hits
New, conical spiral back. Narrower spiral back after the drill point for faster drill dust transport, higher drilling speed and lower friction. Wide spiral back towards the drill shank for higher stability and lower risk of breakage. Drill up to 20% more holes per battery charge compared to a standard 4-flute drill in concrete.
Made in Germany
