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.

Very happy with result

I used this when I exchanged the not so great machines on an epi LP with Grovers.
I removed the existing tuners first, constructed a jig to support the guitar, and turned the reamer by hand in my drill press. It was sharp and cut surprisingly quickly.

Works great on Fender/Schaller locking tuners too.

A customer dropped off a made in Japan Foto-Flame Fender Tele for a setup and installation of new tuners at my shop, String Theory Guitar Repair. This reamer was instrumental in helping me get a set of Fender/Schaller locking tuners installed to replace the crap factory tuners. Nice tight fit and with the Stew-Mac tuner hole jig I was also able to drill perfect dual alignment pin holes too!

The perfect tool

This was the perfect tool to upgrade my stock Epiphone tuning machines with press in bushings to Grovers with threaded bushings. I am glad I bought it.

This worked perfectly to enlarge the holes for the new Grover tuners I was installing. Zero chipping, very clean hole. I have the 6 holes drilled and the new tuners installing in minutes.

Highly recommended

I will echo what everyone else has said-this tool is indispensable for what it does. I used it to enlarge pegholes on an Epi LP Jr. from 8mm to 10mm to upgrade the tuners. If you need to enlarge pegholes to accommodate modern sealed tuners, use this, and follow others' advice and go slowly with it.

Game Changer

As a guitar repair tech in my spare time, this tool is a game changer. No more reaming out the tuner holes by hand. This makes short work of the job of putting new tuners on. and the fit is perfect every time. Thanks!!!

I was worried since I've never done this before and the dimensions didn't seem exactly right but it worked great. No fancy drill presses, just my hand drill. Quick and easy!
