What is stitch drilling?

Stitch Core Drilling or Stitch Drilling can be used to create large openings and slots in walls or in floors particularly so in areas where access is difficult or restricted. Stitch drilling uses a series of overlapping core holes to create the opening required. It is often used when other drilling methods won’t achieve the required outcome. So what is stitch drilling and how is it different to other drilling methods?

What is the difference between core drilling & stitch core drilling?

A core drill is a cylindrical hollow drill, used to drill holes in a surface and made of metal. The drill tip is usually coated with diamond or tungsten carbide and the drill head with some kind of metal coating.

The center of the drill is hollow, so that it can cut a sample from the drilled material. This sample, known as a core sample, corresponds to the shape of a cavity in the wall of this drill.

A core drill consists of both a motor and a handle for drilling, so it is not necessary to extract samples from a material or drill holes in it.

A core drill can penetrate different surfaces: it can cut cement, wood, rock, ice, etc. The surface is pressed down in a rotational motion to create a hole, and the core penetrates through the surface.

To ensure the best performance, different drills must be installed on each surface. Size and performance of a core drill may vary depending on the purpose of the drill. Smaller core drills are used by individuals, while powerful, medium-sized drills can be used for buildings and mines. In massive construction projects, concrete is usually cut with large drills.

Stitch core drilling is core drilling that is repeated to enable bigger drills and more customized jobs to be done.  As per the clients requests.

Stitch core drilling offers solution for hard to work in areas, hence the name “Stitch core drilling” as the surface is stitch drilled. Multiple holes are drilled into a surface to create a wider hole.

instead of using heavy machinery to drill these holes, using the stitch core drilling method; lowers the cost and labour involved. Despite the obvious cost savings stitch core drilling also allows a core drilling team to reach and work in dangerous or hard to reach and fragile areas.

What are the benefits of stitch drilling?

  • Having the ability to cut an unlimited size of openings or shapes through ANY thickness. Other drilling methods may  be restricted by size openings which can be made so using stitch core drilling helps overcome this by making use of a series of overlapping core holes.
  • Stitch core drilling can be used when diamond drilling won’t quite do the job. Diamond drilling is often restrained to 1500mm so stitch drilling can take on more complex jobs.
  • The depth of the substrate is small, but too deep for the usual sawing method, and sawing is not practical due to the lack of space between the two layers of material. Stitch drilling can resolve this problem by drilling smaller holes to form a greater sized hole.
  • It is often the safest and preferred method and works in a controlled environment with a high level of safety and quality control. It works because cutting waste and cutting products is easy to control and contain and can be processed in a controlled environment.
