Outstanding performance compared to similar uncoated core drill bits
- Significantly higher service life
- Up to 60% greater cutting speed
- Considerably faster drilling progress
AlCrN multilayer wear-protection coating and 8% cobalt alloy
- Extremely high temperature resistance of up to 1050°C
- Very high coating hardness of 3000 HV
- Multilayer construction for optimum chip removal and improved cutting properties (prevents material wear)
For process reliability in almost all materials
Exact guidance, no slippage
Problem-free drilling on curved surfaces and pipes
No predrilling required, no formation of burrs
Eliminates need for pre- and post-machining
- 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 during the entire drilling process considerably increases the service life of the core drill. Do not use in a dry state.
- 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
Datasheets(X)
- With Weldon shank ∅ 19 mm for use on mobile magnetic drills or stationary drills for creating large holes up to 50 mm in diameter and a cutting depth of max. 55 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
