impregnated diamond non coring bit hole sizes are available in 56mm, 60mm, 76mm. The drilling portion of the non coring bit is unique for the matrix of it is impregnated with diamonds. The idea behind impregnating the diamonds within the drill bit is quite simple. Given that diamonds are prone to breakage from constant or prolonged impact and pressure, supporting them by protecting them with the non coring bit provides a stronger solution. Hence, the support coupled with the strength of diamonds equates to better functioning of the non coring bit. This combination of types of synthetic diamonds and metal powders help for increasing protection.

The non coring bits design behind it is aiming to cover the well bottom with the diamonds which lead the drilling. In this, different diamonds are exposed to drill at different times and not simultaneously altogether. This allows fresh and sharp diamonds to be exposed at different times and hence, increasing the effectiveness of the drilling process. This type of non coring bit is ideal for gas content coring, gas drainage, and mineral exploration. Some things that influence the effectiveness of the drill include variation of size, distribution ratio to matrix volumes and so forth. The variations of diamond distribution affects the aggressiveness and durability of the non coring bit.

Size wise, the diamonds are relatively small. However, they are cut in a manner which they decrease rotational speeds. Considering this, these types of non coring bits are not well equipped for rotary drilling due to the low speeds. On the other hand, these drill bits can be run together with high speed positive displacement motors and turbo drills to increase the rotary speed. This is one way the impregnated diamond non coring bit can be modified for use in rotary drilling.
