Product Description

It is suitable for drilling water wells , geothermal wells , short miscopies ,medium mini-type grouting hole of
building , dam and harbor project .

1. Ring bit and casing shoe assembly is welded to casing prior to drilling. Lock the assembly into pilot bit with hammer. The pilot bit’s upper shoulder engages the shoulder of the casing shoe.
2. Hammer’s percussive energy is transferred through the pilot and ring bits, crushing rock . Part of impact energy advances casing.
3. On completion of drilling and casing , the drill string with pilot bit is retrieved by a slight reverse rotation to unlock the bayonet coupling . The ring bit stays in the hole , and can be recovered only if the casing is retrieved
4. If further drilling is required on the bedrock,the pilot bit is simply repiaced by an appropriate size of standard DTH bit.
