Flint aggregates as found in the South East of the UK were too hard to cut and it was UK companies who developed diamond bits able to economically cut the material.

Diamond drill bits consist of a steel tube on the end of which are brazed segments made up of compressed and sintered diamond grit and metal powders. The infinite variations and mixtures of these expensive materials are the toolmakers art and science and is the basis of economical drilling as we see it today.

Diamond bits in the construction industry come in a range of sizes from 10mm diameter for fixings up to 1000mm diameter and exceptionally much larger than this for one off jobs.

Diamond drilling produces clean holes with no structural damage through all types of construction materials, and is used for the installation of fixings in the smaller sizes and forming holes for the passage of all types of services. Larger holes can accommodate large service penetrations such as are required in the water, sewage and nuclear industries. Stitch drilling by drilling a series of overlapping smaller holes can be used to form irregular shaped openings or cut through concrete sections. Holes several metres in depth are possible for the installation of tie bars in structures and proving the thickness and makeup of structures for instance before upgrading is carried out.

Concrete Cutters have a full range of drilling equipment from small high speed electric rigs through to large lorry mounted rigs for heavy duty pavement drilling plus the associated support equipment for fixing and water control etc. Concrete Cutters have the largest fleet of trailer and lorry mounted drilling rigs in the country.

Recent contracts have included drilling 10mm dia. holes in a marble topped counter in an airport duty free shop for the passage of IT cabling up to 750mm dia for the removal of redundant airfield lighting units.
