Adjustable Reamer, 15.1mm to 16.7mm

The perfect tool to repair out of round valve casings.  These quality American made reamers are precision made and very sharp.  Beware of cheaper alternatives!

• For use on small Cornets and Soprano Clarinet.
• Quality adjustable reamer. 
• Expands from 15.1mm to 16.7mm or 19/32 to 21/32.
• Can also be used on Woodwind Instruments.   
• Replaceable blades.

The reamer blades are so accurately ground that you can replace them easily yourself.

Using the adjustable reamer is easy.   The nuts have two flats on them and you can use an adjustable spanner to tighten / untighten. Unscrew the top and bottom nuts to push the blade to its minimum cutting width.  Insert into the valve and adjust until the blade starts to make contact with the casing.  Go easy at first and keep adjusting until you can feel the blades bite into the brass.
