What is Diamond Stitch Drilling?

Diamond stitch drilling involves drilling a series of overlapping holes in a stitch-like pattern around the perimeter of the opening. After this, the remaining central material is removed and the edges finished to create the opening.

Diamond stitch drilling can be used to cut holes and openings of any size, shape and depth. The largest diamond drill bit measures 1500mm in diameter, so when a larger hole is required, diamond stitch drilling would be the most efficient option.

How does Diamond Stitch
Drilling work?

To create large openings, our operatives drill a series of holes in the material in a stitch-like, overlapping pattern. Once the perimeter is drilled, the isolated central section is removed through hydraulic bursting or breaking. If required, the edges of the opening can be smoothed to a perfect shape (e.g. a square or a circle).

What is Diamond Stitch Drilling used for?

Diamond stitch drilling is popular for creating door, window, and lift openings through materials such as reinforced concrete, brick, blockwork and stone.

When diamond stitch drilling you are able to cut virtually any shape or size opening where precision is key.

Diamond Stitch Drilling

Diamond drill bits range from 10mm to 1500mm in diameter. In some cases, a larger area may need to be drilled. In this case, a technique called diamond stitch drilling is the ideal solution.
