Diamond Drilling is a form of core drilling which uses a rotary drill with a diamond drill bit attached in order to create precisely measured holes. As diamond is the hardest naturally occurring material in the world, it is ideal for creating openings in a range of materials including concrete, metal and glass.
What are diamond core drills used for?
This is the reason that diamond-tipped core drills are commonly used in construction to create holes for pipes, manholes, and other large-diameter penetrations in concrete or stone. Core drills are used frequently in mineral exploration where the coring may be several hundred to several thousand feet in length.
What is a diamond core bit?
Diamond core bits are used for drilling holes in hard and soft materials with or without steel reinforcing, such as cured and reinforced concrete, pre-stressed concrete, asphalt, brick, block, stone for air-conditioning, water pipe, gas nozzles, electric switches in walls and floors.
Why is it called diamond drilling?
The term diamond core drilling comes from the ‘diamond bit’ drill used during this process. This drill bit is made up of a group of small, industrial-grade diamonds set into a metallic, soft matrix. As the ground is drilled this matrix will wear away and expose more diamonds.

Will a diamond bit cut metal?
Diamond Drill Bits
The use of diamond, the hardest material known to man, makes these drill bits extremely suitable for drilling through steel. Diamond drill bits are more expensive than standard drill bits because the manufacturers use such a precious material , and for their unique ability to cut into steel.
Do you hammer drill on core bit?
As we have already stated but will do so again, never use hammer action when core drilling. The drilling action needs to be as smooth as possible and the jerky action of the hammer can snap expensive diamond teeth very easily.
Will a diamond core bit cut through rebar?
Diamond core drilling is a high-speed, high-production method of drilling in concrete, stone, asphalt or masonry structures. … Core drills cut easily through rebar, allowing the holes to be placed wherever it is most suitable.
What is the difference between a core drill and a hammer drill?
Hammer drills are smaller and more compact than diamond core rigs and are ideal for smaller jobs. Percussion carbide bits are most often used with hammer drills because cheaper bits will not withstand the pressure of the impact created by a hammer drill. Holes up to 6-inches can be drilled with a Hammer Drill.
What is the difference between RC and diamond drilling?
The kind of sample each drilling method allows differs. Diamond core drilling is good for precise sampling and analysis of layers; RC drilling is good at extracting bulk samples. Drilling rate can depend on the ground conditions but RC drilling tends to be quite a lot quicker than diamond core drilling.
What are diamond drills made of?
The diamonds themselves are made from epoxy resin and are 2.8 mm in size, though some budget manufacturers use lower grade plastic or recycled materials. Diamond drills come in either a round or a square shape.
Who invented diamond drilling?
1938 – New heights. Before the start of WW2, Branner Newsom, a Californian mining engineer created a core drill which dwarfed its predecessors. Suspended by giant steel cables, Newsom’s drill could take out huge-diameter cores up to 16 feet in length for mining shafts.
