5th String Peghole Reamer

About This Item

The right tool for correctly tapering a 5th string peghole in a new neck, or for enlarging a standard 5th string peghole to fit a new geared 5th peg.

We've supplied our specially modified reamer to banjo makers for over 30 years. This fluted reamer has a 6-degree taper, from 1/2" to 21/64" (12.70mm to 8.33mm).

Hardened steel.

Worked fine for me.

(Customer's Reviews)

The reamer bottomed out in the old hole before it was large enough for the new geared peg. I had to drill out the hole until the drill hit the neck adjustment rod. At that point, I was able to ream the hole large enough to lightly tap the tuner into place. No glue. There was a little less that 1/8 inch of the serrated part of the tuner showing when I tapped it in. Seems to be tight and holding very well.


nice tool

this is my second fifth-string peghole reamer . It became obvious that I waited too long to replace the old one. The new one cut so much nicer than the old one.

Low grade, cutdown import. Scrapes more than cuts.
Not up to Stewart-MacDonald"s usual high standards.
