1-step Peghole Drill Bit

About This Item

For Grover, Schaller and Gotoh sealed tuners. Custom dual-diameter bit for drilling rear-counterbored pegholes for popular sealed tuners.

This tool quickly pays for itself in a busy guitar shop—it does the job in one operation, so you'll get the work done in half the time. It's 7.8mm-diameter (.307") for the threaded peghead bushing, and 9.9mm (.390") for the gear housing. The brad point helps center the bit accurately for a clean, professional job. High speed steel.

Why counterbore the pegholes?
The collar on a sealed tuner's housing has a larger diameter than the threaded peghead bushing. Under string tension, the installed bushing (and the peghead washer) can lean slightly in a constant-diameter peghole. This can damage the lacquer finish around the bushing washer. A peghole that's properly sized for the bushing, and rear-counterbored for the housing collar, prevents the problem.

This unique bit works for Grover, Schaller and Gotoh sealed tuners that require 10mm (13/32") pegholes.

It's about time and accuracy.

(Customer's Reviews)

Drilling or reaming holes for tuners has always been a challenge and time consuming. With this tool I've saved time and increased accuracy. I can't believe how much it cost but in my opinion it has paid for itself the first time I used it. It's helpful to use a backer piece of wood to avoid blowout or chipping.


Why did I wait so long?

(Customer's Reviews)

Hesitated and then hesitated a lot more. No reviews to say this was worth the money, so I perservered with the drill bits I had. Now I feel really stupid...and you will too if you have hesitated as long as I did before buying this. Yes, it is pricey but it does a fine job and saves time whilst providing solid support for the tuners. Highly recommended!
