This machined steel 2-step reamer is made specifically for enlarging a guitar endpin hole to accept a 15/32" or 1/2"-diameter endpin jack.

It won't chip the finish, and it's semi-fluted to help keep the hole round.

The 3/8" shank can be chucked in a hand drill for slow reaming. The upper 1" cutting length is 1/2" diameter; the 1" center section is 15/32" diameter, and the lower 2-5/8" section has a standard 5-degree endpin taper to 1/4".

Where have you reamed all my life?!

By Ramsay Phillips from Dubai, UAE
(Customer's Reviews) Sunday, May 15, 2011

I decided to finally go ahead and splash out on this specialized tool. I should have splashed out two years ago!

What used to be a 20 minute job of creating a perfect hole for an endpin jack is now a 1 minute job.

I just had to install a Baggs Anthem pickup in a Martin Benezza Bianca, and I could do it with confidence.

I LOVE this reamer. Thanks Stewmac!

If you're fitting end pin jacks in acoustic guitars this reamer is just the very best tool for the job. No risk of damage to the finish and it cuts quickly

Great tool and cuts well although I would prefer a `t` handle instead of using it in a drill.

This tool, along with Guitar Player Repair Guide, made installing a pickup in my Martin a piece of cake. Take from Dan Erlewine himself, jobs like this are always easier when you use the proper tools.

Expensive - but I would not attempt an endpin installation without it.
