Double Reamer


What is it?

 

This is the original reamer bit as described on page 17 of the Practica manual

Good Things

  • Quite strong
  • made from easily available materials

Bad Things

  • The pipe can break where it meets the socket especially after wear from the pipe wrenches
  • The teeth can also break off especially if rock is met. If anything breaks off it can stop the drilling continuing downwards
  • It will become clogged if not used with the smaller bit first


Your Ideas

MSABI weld pieces of flat bar between the socket and pipe to strengthen it
