What is Stitch Drilling and why is it used?

​

Stitch Drilling is a combination of core holes that are drilled overlapping the previous to form an opening in walls and floors or to separate one structure from another. 

 

Stitch Drilling eliminates limitations caused by other factors such as drill sizes or shapes that need to be removed.

​

Due to the nature of this method it allows for a greater flexibility than other options especially in confined spaces and restricted access.  It is a viable option when smaller and unconventional shapes need to be achieved.

​

Stitch Drilling has key features that make it the perfect solution - it is quick and relatively non-vibrational, non-destructive (preventing structural damage), relatively low noise omission, no dust creation, less debris production, equipment is lightweight and portable and it also allows for work to be conducted in confined spaces.
