Although it isn't the most affordable reamer available, it is among the best that you can get.

A screw thread at the base controls the three reaming heads, and the machined aluminium body makes it easy to handle.

 Simply spin the base after twisting it to the appropriate width, then place it within your bowl. By doing this, any uneven carbon build will be eliminated. The optimal buildup is about 2 mm overall.

You can either increase the bore or leave it alone after your senior reamer is spinning freely.

Anything in the stem that a pipe cleaner cannot remove can be removed with the help of a drill.

Your pipe will smoke at its best if the carbon is kept low, which will increase your enjoyment.
