Standard annular cutter made from HSS for drilling large through-holes up to 50 mm in diameter with mobile magnetic or stationary drills in conventional steels up to 850 N/mm², wood and non-ferrous metals, such as aluminium, aluminium alloys and plastics.

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 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

Application area
  • With Weldon shank ∅ 19 mm for use on mobile magnetic drills or stationary drills for creating large holes with a diameter of up to 50 mm and a cutting depth of 30 mm or 50 mm

  • Fein drills with QuickIn mount can be used with an adapter

  • Application on stationary drills with Morse taper is possible using the appropriate mount holder
Instructions
  • Insert the ejector pin into the core drill bit

  • Push the core drill bit into the mount holder of the drill unit and tighten the hexagon socket screws

  • The core drill bit is automatically locked into place when using quick-action mounts

  • Make sure the core drill bit is sitting cleanly in the mount

  • Putting the drill under lateral load during use may cause the tool to break

  • Fix the drill unit into the right position for drilling — make sure the drill unit has a stable footing

  • If necessary, secure the drill unit before drilling using a safety strap, especially for use on vertical surfaces and overhead work

  • Pay attention to the speed table and use coolant

  • Drill carefully (without centre punching and pre-drilling), pay attention to an even feed and even rotation speed throughout the entire drilling process

  • Remove chips and drill core after each drilling operation

  • Caution: Risk of injury, chips and drill core may be very hot and sharp
