RIGHT BIT
One of the most important issues when it comes to bit selection is choosing a bit large enough to allow cuttings to get around the hammer and out of the hole. An undersized bit will slow you down, as well as creating backpressure that shortens the life of carbides. It’s also important to start with the right carbide, bearing in mind that the tougher compounds can extend the lifetime of the bit by 2-5 times depending on the conditions.
XT48 works for most drilling conditions and should be the first choice if there’s any uncertainty about the rock type. DP65 is the right choice for hard, abrasive conditions, and DP55 in ballistic configurations gives fastest overall drilling in softer to medium-rock
