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.

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


Just What I Needed

(Customer's Reviews)

Our customer complained her 5th string was not staying in tune. It was a non-geared tuner and the hole was worn out causing the tuner to not fit tightly. We replaced the tuner with a Grover geared tuner and this reamer did a perfect job of sizing the hole properly for the new tuner. The banjo is making a comeback and I'm sure we'll have other customers who want to upgrade their 5th string tuner.


Good tool

(Customer's Reviews)

I bought this to enlarge the holes for my Jazzmaster body to fit a Mastery bridge as they were originally too small for the thimbles. While it helped initally, in the end I enlarged the hole by hand with sandpaper and drill bit, as I didn't want the holes tapered the entire way. It's a good tool, just not exactly the right one for what I needed to do.
