Diamond core drills, sds drills, hole cutters, chissels

Our range includes diamond core bits from 6 mm to 900 mm in diameter. 

Diamond drills are available in various configurations depending on the composition and shape of the segments. 
We offer different options suitable for drilling reinforced concrete, concrete, asphalt, or granite. 
 

Diamond core bits can be designed for: 

wet drilling (using water for cooling during drilling) 
dry drilling (without using water during drilling 

The segments of diamond core bits are laser-welded to the body at the factory. They are particularly well-suited for dry drilling or when using a small amount of water for cooling.
Core bit segments soldered with silver to the body are designed for wet drilling (using water for cooling), because without sufficient cooling, friction causes the segments and drill body to heat up, which may cause the solder joint to fail and the diamond segments to fall off.

When the core bit is worn, the drill can be restored up to 5 times by re-soldering new diamond segments onto the same tube body.
