NEW LACKMOND -250CBEXTTUBE- 2 1/2 DIAMOND CORE BIT EXTENSION TUBE ( 1 TUBE )

Description

Lackmond 2 1/2" Diamond Core Bit Extension Tube The Extend-A-Tube wet drilling core bit system allows for quick and easy extended depth drilling applications. The precision machined extension tubes add an additional 12" to the drill tube length of any of Lackmond's wet core bits. 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. All Lackmond wet core drill bits come with the threaded cap feature and extension tubes are available for bits up to 6-1/4" diameter. We suggest using an anti-seize compound on bit threads prior to use; the anti-seize compound will aid in the future removal of extension tube sections. A strap wrench is also an effective tool in removing more stubbornly attached extension tubes or caps.
