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.

  • Unlike twist drill bits, the annular cutter only machines a thin ring of material rather than the complete bore diameter. The drilling core is removed using a pilot pin with spring power, which is not included in the scope of delivery. Annular cutters therefore offer a drilling time that is 10 times faster than twist drills bits.

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

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

  • For materials and cutting value parameters, see the summary overview tables

  • Wear appropriate protective equipment, such as eye protection, hearing protection devices and protective gloves

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

  • Annular cutters must not be used with hand-held tools

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