Specify the following parameters when ordering: Casing Tube OD + Casing Tube ID + Reamer Bit Diameter + Minimal Casing Shoe ID + Hammer Shank Style.
Ideal for water wells, geothermal wells, micro piles, and medium mini-type grouting holes in building, dam, and harbor construction projects.
Down-the-hole drilling (DTH) involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.
The Casing Advancer allows drilling and casing to be carried out simultaneously as one integral operation. This eliminates the need to drill the large diameter hole with a Rock Bit, pull the drill rod string and Rock Bit from the hole, and then ream the casing back into the hole.
Most air tools require between 70 and 90 PSI. Always respect the PSI rating and ensure your compressor supplies adequate air volume for proper tool operation.
