The application of drill bits

Product performance continue to improve over the past few years, the quality and type of the cutting teeth have undergone tremendous changes. If the 1980s and today's tooth, then the teeth were compared, the difference is quite large. Due to changes in the mixing process and the manufacturing process, the quality of the performance of today's cutting teeth is much better, so that the anti-erosion and impact diamond core drill bit capabilities are greatly improved.

Engineers also tungsten carbide interface between the substrate and the synthetic diamond is optimized to improve the toughness of the cutting teeth. Layered diamond workmanship innovation has also been used to improve the abrasion resistance and thermal stability.

In addition to the development of materials and manufacturing processes, product design techniques in the tooth and the tooth cloth has also achieved a major breakthrough. Products can be used in areas not previously applied, such as harder, more abrasive formations and varied. This extended to the new field, to balance between the drill bits and the roller cone diamond core drill machine diamond (fixed cutter) had a great impact occurs.

Initially, the drill bits can only be used for soft shale formations, because it will damage the drill bits hard mezzanine. However, due to the emergence of new technologies and changes in the structure of the drill bits can be used in hard rock formations have been Non-core drill bit hard and long segments of the mezzanine. drill bits is increasingly chosen by the people, especially with the cutter quality continues to improve, this situation more and more prominent.

Matters drill bits during use should be noted

Always check the concentricity of the clamping force of the spindle and collet and collet chuck, concentricity good cause broken drill bits small diameter drill bitsing and pore size, etc., the clamping force is not good cause actual speed and set speed is not met, the slip between the chuck and glass drill bit.

Shank drill bits set at the head of the clamping length collet shank diameter of 4 to 5 times in order to clamp securely.

Always check the spindle presser foot. Presser foot contact surfaces must be level and the vertical axis can not shake off the drill bits to prevent sds plus hammer drill bits produced and partial holes.

drill bitsing is better suction, vacuum wind can reduce drill bits temperature, while away the dust reducing friction heat.

Laminated substrate including the upper and lower plate to be positioned firmly in the work bench drill bitsing a hole in a trough positioning systems, flat. The need to prevent the use of adhesive tape on the diamond core drill bit so that the tape adheres drill bits cuttings, causing difficulties and chip off the diamond.
