Diamond Stitch Drilling Services
Diamond drilling holes has many advantages over conventional drilling methods as the diamond bit can drill faster and more accurately through a range of hard materials, with one drawback – the drill bits don’t come in sizes any larger than 1500mm which makes drilling larger holes than this difficult. This is where a process called stitch drilling comes in, allowing us to creating openings of any size and shape and to an almost unlimited depth.

WHAT IS STITCH DRILLING?
Diamond stitch drilling is an incredibly effective method for creating large or irregular openings in almost any thickness of concrete. This technique works by ‘stitching’ or drilling slightly overlapping adjacent holes through the surface and then removing the central material.
HOW DOES CORE DRILLING WORK?
The set up for stitch drilling is the same as for diamond drilling – an electric or hydraulic powered rotary drill is mounted on a rig and fitted with a specialist hollow cylindrical drill bit which has diamond teeth welded to the end of the core barrel. The rig is then moved along bit by bit until a row of holes are formed in a stitch pattern. Our diamond drill bits are perfect for cutting through tough construction materials like reinforced concrete, masonry, stone and asphalt and our rigs can be placed either vertically or horizontally depending on site requirements.
WHEN TO USE CORE DRILLING?
There are a number of other ways to create larger openings through concrete or other hard construction materials, however there are a few situations when stitch drilling is the preferred method. This includes on cramped sites or when access is limited as diamond drilling rigs can be set up in confined spaces unlike other methods of cutting. Additionally, because we run water through the drive shaft to lubricate and cool the drill bits, very little dust is produced making it the ideal solution for environments such as hospitals, schools and other buildings which remain in use as works continue.

Frequently asked questions — stitch drilling
What is stitch drilling?
Stitch drilling creates large openings by drilling a series of overlapping or adjacent core holes in a line or pattern. Once complete, the remaining web of material breaks away cleanly, leaving an opening of any size or shape — far larger than a single drill bit could achieve.
When is stitch drilling used instead of saw cutting?
Stitch drilling is used when access is too restricted for a saw, when the cut must follow a non-linear path, or when the slab is too thick for a single saw pass. It is also chosen where vibration or water use needs to be minimised.
What sizes of opening can be created?
There is no practical upper size limit. We have created full-height door openings, service risers, and structural apertures of several metres. The lower limit is typically a few hundred millimetres.
Do you need a structural engineer’s approval first?
For large openings in structural elements, yes. We always recommend involving a structural engineer to confirm the load path and specify any temporary propping or lintel requirements before drilling begins.
Is a ferro scan required before stitch drilling?
Yes — essential. Rebar positions determine exactly where each hole is placed. We carry out a ferro scan before marking up hole positions, ensuring every core is in a safe zone.
