Diamond Drilling
CODICUTS carry out diamond drilling to form precise holes and penetrations in solid materials including reinforced concrete, masonry, asphalt, rock, brick and block work using a core drill tipped with teeth containing industrial diamonds.
The drill rigs are light weight and can be set up to accurately drill holes at any angle from 8mm to 1000mm + from the horizontal to the vertical including inverted. The drills are driven by electric, hydraulics or air and have a non percussive rotary action which means there is no exposure to vibration for the operator or damage to the material being drilled, noise levels are also low. The drill is water fed to cool and lubricate the bit and remove the cuttings this also means there is zero dust emitted to the site.
Applications
- Openings for services
- Holes for lights / street furniture
- Anchor bolt holes
- Pile guide holes
- Material sampling
Large Diameter and Deep Holes
Holes greater than 800mm in diameter are considered large diameter, they are typically cut using a hydraulic drill motor mounted upon a heavy duty stand. Horizontal holes may require guide rollers and additional rig fixings together with lifting equipment to remove the heavy core once drilled.
Deep holes are achieved by using extra long core bits together with an extended drill rig column or alternatively using drill rods screwed between the drill and the core. Cores are recovered using specially designed tools.
Applications
- Manholes
- Large diameter pipe penetrations
- Pile holes for structural reinforcing
- Boreholes
Stitch Drilling
Stitch drilling involves the diamond drilling of a series of overlapping holes to form openings of any size or shape in reinforced concrete, masonry, stone, block or brickwork of virtually any thickness. Typical applications are for circular openings larger than can be drilled with a single core, structural modification or controlled demolition. Due to the relatively small size of the drill rigs stitch drilling can be used in confined spaces where larger cutting or demolition equipment cannot.
Dry Drilling
Dry drilling can be used in dry un reinforced materials such as brick and block work, the core bits differ from those used in wet drilling and are slotted to allow for drilling particles to escape the hole as dust. Drilling is usually carried out for smaller diameter holes up to 200mm using hand held drills equipped with fittings for vacuum equipment to control dust and minimise its exposure to the work place.
