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.

Notice
  • Unlike the twist drill, the core drill bit does not machine the entire bore diameter, but rather only a thin material ring. The drill core is ejected by an ejector pin using spring tension; this is not included in the scope of delivery. The drilling times of core drill bits are therefore up to ten times shorter than those of twist drills.

  • Sufficient, continuous cooling throughout the drilling process significantly increases the service life of the core drill. Do not use in a dry state

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

  • See the overview tables for core drill bits/material assignments as well as cutting values

  • Wear appropriate protective equipment when using the sanding tip, such as Eye protection, hearing protection, protective gloves

  • Set aside loose clothing or jewellery that could get caught in moving parts

  • The core drill bits must not be used manually

  • Before use, please ensure that the tool rotates properly and that the clamping function on the tool drive works correctly
