Perfectly formed round holes drilled with precision in exactly the position required, through all types of construction materials.
 
Size ranges from 10mm to 750mm available in standard options with special sizes up to 1500mm made to order.
 

Large openings can be formed by stitch drilling when wall and floor thickness prevent the use of sawing equipment. 

Drill rigs can be powered by 110v electric motors, hydraulic or air motors which allows work to be carried out in almost any environment.
