Long service life, fast drilling progress, precision drill holes - top quality!
Innovative, robust 4-edge drill head and 4-spiral reinforced-core coil for unrivalled service life, precision drill holes and low vibration.
Field of Application:
Concrete, reinforced concrete, sand-lime brick, solid brick
All dimensions with a working length greater than 400 mm should be pre-drilled to at least 150 mm with a short drill of the same diameter!
- The centring point drills with pin-point accuracy and prevents runout
- The core-reinforced spiral accelerates the transport of the cuttings and optimises the impact transfer
- The robust head geometry and solid cemented carbide plates with patented reinforcement chamfering are designed for the toughest applications.
- The wear marker is used to assess the dimensional accuracy of the anchor holes. If the edge is no longer visible, the end of the service life has been reached and dimensional accuracy is no longer guaranteed.
