RC Bits

We carry a large inventory of RC bits for convenient and quick delivery. Standard bits come with higher grade carbides for longer, harder drilling performance.  Diamond buttons are available by special order on all bits. Economize the diamond button cost even more by reclaiming the used diamonds (if in good shape) and have them reinserted in to a new bit body.   Please contact us for additional details.
