Rear Peghole Reamer

About This Item

Counterbores the back of a 5/16"-diameter peghole to fit Grover and Gotoh sealed gear housing.

Here's a tip from our luthier friend Bryan Galloup: Grover and Gotoh tuners with threaded bushings should be installed in counterbored pegholes. A snug 5/16" diameter at the top of the hole stops the bushing from leaning under string pull, thus helping to protect the lacquer finish around the bushing washers. At Bryan's suggestion, we developed this special slow-speed steel reamer that accurately counterbores the bottom of the peghole to fit the gear housing.

The reamer has a .310"-diameter (7.87mm) pilot and two flutes that cut a .397"-diameter (10.08mm) counterbore in a 5/16"-diameter (7.94mm) peghole. When the reamer's piloted end is flush with the face of the peghead, the correct counterbore depth has been reamed.

Got this to re-ream some vintage bore pegholes on a new tiltback neck to accept Grover Deluxe vintage-look sealed tuners.

Mounted a piece of plywood to my drill press to act as a depth stop for the tip of the reamer. Reamer was razor sharp. Worked perfectly. The tuners fit like a glove with just enough play to go in easy but not wiggle in the hole.

After stringing it up, the tuners worked fine.

My advice to anyone using this is use a drill press and WORK SLOW a little at a time. Make sure you clamp the peghead tight to your press so it doesn't move.

Who knows if I'll ever use it for another job, but it was cheaper then buying a new custom neck!

Floyd Rose Stud hole enlarger

I used this tool in an unconventional way, to make the Floyd Rose studs fit. (both are 10mm) High quality tool, works far better than a drill bit if using a power drill by hand.

I'll be using this to replace some guitar tuners as well. :-)

Rear peghole reamer review

This thing is the cat's pajamas! Chucks up in a standard 3/8" drill chuck and with the pilot it bores down to the exact correct depth for the Grovers I installed. I clamped the headstock face down on my workbench and simply drilled until the pilot stopped it. 6 perfect holes in as many minutes. If you are even thinking of installing Grovers, add this to your order. You won't be sorry.

Worked perfect for a set of Grover 502's on a 2017 Epiphone Led Paul Special II. Put in from the back side of the head stock and turn by hand until the tip is flush with the hole on the front side of the headstock.
