High performance and rapid drilling progress with a long service life

In contrast to solid drilling, only a thin metal ring is cut. The drill core is ejected by an ejector pin.

No pre-drilling required, no formation of burrs

No pre- or post-processing required

Optimised cutting geometry

  • Long service life compared to many standard core drill bits

  • Clean drill profile

  • Drill hole with precise tolerances

Precise guidance, no slipping

Suitable for overlap drilling. Problem-free drilling on curved surfaces and pipes.

  • In contrast to twist drills, the core drill does not machine the complete bore diameter but only a thin ring of material. The drilling core is taken out using an ejector pin with spring power which is not included in the scope of delivery. Core drills are therefore up to 10 times quicker in terms of drilling time compared to twist drills.

  • Sufficient continuous cooling during the entire drilling process considerably increases the service life of the core drill. Do not use dry

  • Not suitable for pressboard, titanium or heat-resistant and high-alloy steels

  • For core drill/material allocations and cutting values, see the overview tables

  • During use, wear appropriate protective equipment, such as eye protection, hearing protection and protective gloves

  • Take off loose clothing or jewellery which could get caught in the moving parts

  • Core drills must not be used hand-guided

  • Before use, ensure perfect concentricity and the correct clamping function of the tool drive
