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
- 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
- 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
