Diamond Bits

Rockdril manufactures a large variety of Diamond Drilling and Coring Bits for :

  • Mineral exploration and foundation investigation application. These are manufactured to various international standards. We also engineer and manufacture bits to suit individual customer specific requirements.
  • Industrial Thin Wall Impregnated Diamond Core Bits for drilling through stone, masonry, concrete etc. in sizes from 10mm to 450mm Diameter.
  • For Oil Well Drilling we manufacture a wide range of Drilling and coring bits in sizes up to 311mm (121/4") in various styles and designs as per international specifications for drilling different types of formations.

The Diamond Bits are generally of following two types :-

  • Surface Set Bits : They consist of a single layer of diamonds distributed and set in a pre-Determined, geometric pattern on the surface in an abrasion resistant matrix.
  • Impregnated Bits : In these bits small diamonds or diamond powder is used. The diamonds are distributed throughout the bit crown matrix to a specified depth. During use the special matrix, in which diamonds are impregnated, wears out constantly ensuring that new, sharp diamonds get exposed and become active for drilling.
