4-cutter drill head and reinforced-core coil for a longer service life and precision drill holes

Field of Application:

Concrete (also reinforced), sand-lime brick, solid brick

Advice:

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!

Notice:

We recommend treating the machine chuck and insertion end of the drill with lubricants from our arecal range following extended use (art. sub. no. 0896).

Advantages:

• 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 4-tip drill head is more robust, drills with pin-point accuracy and prevents jamming in case of lateral reinforcement impact
