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.

Slightly large hole for 510 tuners

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.
