Rear Peghole Reamer

About This Item

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

For Grover, Schaller and Gotoh sealed tuners!
Here's a tip from our luthier friend Bryan Galloup: Grover, Schaller 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.

I haven't used this reamer yet but it sure will help y stubborness, I was finishing up a guitar I made and thought as last time just use two different bits and get the job done like always. always didn't work on this peg hole the bit grabbed the wood on drill for the tuner sleeve and drill completely through, not just once but twice, I was able to lack a repair and finish the build. Thanks StewMac for all the help.

Amazing

I could not find direct drop-in replacement tuners that I liked for an Epiphone Casino Coupe headstock, so I eventually landed on Grover 135 series and needed this reamer to open up the peg holes.

It is incredibly easy to use, and you do not need a drill press to use this although it is recommended. I used a regular drill, and if you have one that can handle bits 3/8" or larger and can drill slowly, you'll be fine. Slowly is the key word here. Once the top of the reamer is flush/ level with the headstock face, you're good to go.

This was absolutely perfect for my 97' Les Paul Classic!! I Now have Other Friends who want me to drill their Les Pauls and other vintage instruments for upgrading Tuners...Not Sure why Gibson doesn't drill all their headstocks the same, but this reamer is Amazing!!!

Slightly large hole for 510 tuners

By
(Customer's Reviews)


The hole was slightly large for medium 510 tuners. This reamer is .397" versus .393" for another reamer on the SMc website. I selected this one for the correct 5/16ths pilot. I painted the hole with super glue to give a nice snug fit. Provided good clean cut with little chip out.

This is the right tool for the job

I bought tuners from another website only to find out my pegholes weren't sized properly. A bit of research suggested this was the best product on the market for this problem. While skeptical, I chucked it up into my drill, clamped a board to the front of the headstock, drilled through very slowly. No chips, No fuss, No mess. The whole process took 15 minutes, and the end results fit like a glove. Buy this.

this works like a charm. made my new Grover locking tuner install a breeze. I just marked the depth I needed with some tape on the reamer and I was finished in about 10 min. worth the cash imo.

I used this reamer in my drill press on the lowest speed. It worked great! It automatically reams the correct depth. Just send it through until it stops. Easy!
