More and more architects and engineers are specifying non-overcut openings, especially in load bearing walls.
Core drilling the corner is no longer necessary using the Diamond Chain Saw, corners can be cut square in a matter of minutes. 
The Diamond Chain Saw system is a major step forward in obtaining better and quicker results. The Diamond Chain Saw can plunge 375mm from one side and create a perfectly square corner. |

Until now, the only way to saw an opening without overcutting was to core drill the corners.
This is an expensive, time consuming operation and when finished the opening needs patching up.
In fact, a concrete doorway opening, 300mm thick can require 3-4 more hours extra time to core drill the corners.
