- Drill holes using an air hammer drill and appropriate drill bit specific to the rock type. (Diagram 1-1)
- Holes should be drilled no further than 30-60cm (1ft-2ft) apart. Note: In reinforced concrete recommended no more than 20cm (8”) apart. (Diagram 1-3 & 1-3b)
- Recommended hole diameter 38mm - 50mm (1 ½" - 2.0"). Depth would be 70-90% of the way depending on the type of rock/material to be removed.
Drilling Technique 1
This drilling design is ideal for concrete demolition and rock breaking where there is very little regard for the outcome of the rock being broken up.
Drilling Technique 2
Cutting technique #2 allows for precision cutting of materials where waste is kept to a minimum. This can also be used where the surrounding material needs to remain intact. Perfect for controlled concrete cutting, building remodeling or marble & granite quarrying.
Drilling Technique 3
