Endpin Jack Reamer

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".

Stewmac's Finest Tool

This is the best thing I ever bought from Stewmac.
It prevents the possibility of serious damage to the instrument and works perfectly, gives you the ability to size the hole precisely for the jack.
Well worth the price!

First time with confidence.

I purchased a L. R. Baggs "Lyric" to install into my Martin, Eric Clapton, 000-EC. I discovered the necessity of changing the endpin diameter. I always look to Stew Mac for assistance with any guitar related project. Sure enough not only was a specific tool available but instructions on how best to use it. Yes the price is high but when I received it and saw the quality I felt better. When I picked up one of favorite guitars and used it then I really didn't have any complaints as my Martin had been reamed without any damage! Thanks Dan for another awesome solution to an project problem. (By the way, the end result sounds fantastic!)

Many other use besides endpin jacks

If you need a reamer for fitting endpins or endpin jacks, this is it. It may seem expensive for a reamer, but I was using a repairman's reamer before this and that reamer cuts very wild/jagged holes because the cutter would dig in so deep. The semi fluted design means this reamer will cut wood very well... You can also use it for enlarging tuner holes to fit those 10mm tuners, or even use it to enlarge holes on the guitar body to accept CTS pots... Like others have said a hole or a flat on the shank would be nice, because this reamer cuts very fast, so if you aren't doing just endpin jacks it's very easy to make the hole too large.
