Our Diamond Drill Bits

couronnes-minieres-elite

Elite impregnated diamond mining bits

The exceptional quality of our Elite mining bits make them unique on the market. They have the advantage of being self-sharpening, offer high penetration speeds and increased durability, and will give you the site yields that you deserve to achieve. Choosing an Elite bit means choosing safety, reliability and productivity.

Tornado & Elite diamond impreganted Geotechnical Bits

DATC can also provide a range of diamond-set bits that are impregnated for the geotechnical field. For boring in soft or hard terrain, with or without the risk of polishing, DATC has developed three Tornado core bits and three Elite core bits, the better to meet the cost-quality needs of geotechnical sites.

Wear rates

Understanding and interpreting the wear rate of a diamond coring bit is crucial to your productivity. Examine the main types of wear rate encountered on-site and the corrective measures to be applied in order to gain the maximum yield from our products. Our priority is to help you in your progress towards higher yields.

TECHNICAL DOCUMENTATION 

couronnes-serties

Surface-set diamond core bits

Surface-set core bits are used for boring in soft to medium-hard terrain. Choosing high-quality diamond-bearing stones, our “Processed Drill Premium mechanically polishes the diamonds to ensure that your boring will have the highest shock-resistance and increased productivity. To ensure best quality across the range , our surface-set core bits are available in all profiles and grain-size distributions.

SPECIFICATIONS

couronnes-maxset

Maxset Core bits

MAXSET TSD core bits are designed for terrains with sedimentary rock or arid regions where water supply is a problem. Thanks to the use of air-flush boring, which works well for coring and sounding of sedimentary rock, they ensure a rate of productivity that is three times that of traditional mud-flush boring. They are self-sharpening and heat-resistant and provide excellent interlaminar resistance.

SPECIFICATIONS

couronnes-maxpax

Maxpax PDC Core bits

MAXPAX diamond bits take their inspiration from the oil industry and are fitted with 8- to 19-mm Polycrystalline diamond  chips strategically placed in order to regenerate the cutting surface, reduce the weight of the tool and increase boring speed. You will have the further benefit of increased resistance to abrasion, great strength and high penetration speed in soft or sedimentary terrains.

SPECIFICATIONS

couronnes-carbure

Tungsten Carbide Core bits

Bits with tungsten carbide inserts are generally used for coring softer formations, covered terrain and cleaning soundings. DATC offers hard metal crowns in three forms : PT octagonal prisms, TT longitudinal conical prisms and CCD with chips of ground tungsten carbide, to ensure the clarity of your coring and to suit the conditions under which you are drilling.

Reaming Shells

Because safety on your sites is of fundamental importance, our team at DATC has worked at perfecting reaming shells that fulfil two purposes: reducing the vibrations that are the cause of core-drills being destroyed or boring material suffering from premature wear, and reaming the borehole so as to maintain it at a constant diameter. Our reaming shells ensure the stability of the diamond bits and core barrel to produce a quality core-drill.

Non-Coring Drill Bits

If destructive boring or redirection of the bore is required, you should choose DATC drill bits. DATC drill bits are available in various types of crown : Impregnated, Surface Set, Maxset, Maxpax PDC or Tungsten Carbide, to suit every type of rock when changing from core drilling to destructive boring.

Casing Shoes

For terrains with a high risk of landslip, DATC has developed casing shoes. These tools, when fitted to a casing, make it possible to contain the earth in order to ensure quality core drilling for the borers.
