The bit works good when you drill into bad damaged area of a rock chip. But if you have a rock chip with a very tiny impact point where the bit Will not necessarily stay in one place. Let me explain. If you have a very crushed impact from a rock chip it works great It does. But that's not always the case. if you have a rock chip that has a tiny little impact point where there's just barely any surface damage.
Get PriceRock chips mechanically freed from the parent rock by the drilling action of the bit are generally held in place by overbearing pressures. These pressures must be overcome either by hydraulic action or pressures. These pressures must be overcome either by hydraulic action or by mechanical regrinding before the chip may be removed.
Get Price2015-6-26 · Chip holddown is a well-documented phenomenon associated with mud drilling, especially in deep environments.

The general analysis demonstrates an application of plasticity theory for the rock/bit-tooth interaction to The formulation of an upper limit on rotary drilling rate.
Get PriceThe stress wave energy generated during the impact process is propagated into the rock along the direction of the bit–rock interface, causing damage to the rock near the impact area, which is conducive to improving the rock-breaking efficiency (Saksala et al., 2018, Franca, 2011). Many studies have been conducted to make percussion drilling technology effective for oil and gas drilling.
