Stitch Drilling

Stitch drilling overcomes the limitations caused by the maximum size of drill bits by overlapping (or ‘stitching’) core holes together to form a larger hole. This means we can create openings of unlimited size and shape, through any thickness of wall or floor.

Because of the flexibility that stitch drilling offers, it is also an ideal option where you have smaller openings, confined spaces or restricted access


  • Can tackle jobs where more than 1500mm diameter is required
  • Quick, efficient and non-vibratory
  • Non-destructive: a reduced risk of causing structural damage
  • Very little noise and no dust
  • Less debris produced so saves time and disposal costs
  • Lightweight, portable equipment
  • Ideal for controlled or clean environments
  • Can be remote controlled for extra safety

"2 of your employees, Paul Green and Graham Crowley, completed the drilling project on the Pendine Long Test Track with us today. I’d like to let you know that they carried out their work professionally, effectively and safely. They have done an excellent job within the timeline of the contract and they were a pleasure to have on site."

John Holcroft - Owner of San Giovanni restaurant

"D-Drill carried out the works here in a very safe and controlled manner for the whole time, the workmanship and care they took for the task of cutting down existing culverts and drilling out core holes was brilliant. The client commented several times on this also."

Trant Engineering Limited - Site Manager

"The lads that attended site for us at Kings Lynn were fantastic, both us at TEi and Centrica were impressed with their professionalism, and just how quickly they removed all four of the plinths"

Steamer Quay in Totnes

Flood defence improvement's at Steamer Quay in Totnes Bam Nuttall contacted D-Drill South Wales branch to undertake the removal of the old river defence wall at the edge of the River Dart in the Historic Borough of Totnes in Devon. We were asked to cut the 30m long wall into 2.5m x 1.2m x 300/700mm thick  sections for removal  in a controlled method. We used the stitch drilling method to minimise the amount of water we needed, due to working near the river. We used Weka DK32 drills to stitch drill a series of holes in the wall which was 1.2m high and 300 to 700mm thick and then drilled 2no 100mm diameter holes for the lifting of the 12 sections which was then removed by the site excavator.
