12 ” Core Bits Extend-A-Tube
The Extend-A-Tube Wet Drilling Core Bit system allows for quick and easy extended depth drilling applications. The precision machined Thread-On Caps add an additional 12in to the drill tube length to achieve optimum depth. The machined cap-to-tube connection ensures that bits run correctly and eliminates lateral run-out due to improperly seated or unevenly welded bit caps. Additional 12in tube extensions can be quickly threaded on to extend the standard bit length of 15in to an impressive 27in capacity and more by adding more tube extensions.
