Endpin Jack Reamer

About This Item

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".

Saved my another blister

Bought this for installation for acoustic guitar pickups. Saved me a lot of time and blisters on my hand. Before this I did it with my hand reamer. Great stuff!

Endpin Reamer  digs the right hole

Bought one to enlarge the endpin hole on Gibson mandolin in order to fit new larger endpin. My woodworker friend, Charley, helped my use it correctly to get perfect hole for the new pin. We practiced on scrap wood to get exact diameter hole, tool cut very easily with hand-drill, and first practice try we went too far. Second practice hole was perfect, marked depth on reamer with tape, and then used on mando to get exact size hole, and endpin fit perfectly. If going to complete diameter of drill for jack, this should not be problem.

The very best tool for the job.

I wanted to put a Baggs M80 soundhole pickup in one of my favorite acoustic guitars. To do that, I had to enlarge the endpin hole to one-half inch. I wanted to do that job myself, but I didn't want to chip the finish or wind up with an oval hole. The Stew Mac endpin reamer was perfect for the job. Because of its long taper, it is self-aligning. I put the reamer in my drill, set the drill on it's low speed range, and just took my time. I stopped often to clean out the flutes of the reamer and the result was flawless.

Pretty great!

I used it to install K&K Pure pickups in two guitars and it was excellent. Be careful to go slowly, and keep the bit perpendicular to the guitar. I had to make a few adjustments to the first hole I drilled, but it all turned out fine in the end.

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.

The ONLY tool that works.

I didn't want to damage the finish of my baby, a Guild D-40, and experimented with other tools and found nothing that wouldn't cause some damage around the edge of an endpin hole. Reluctantly, I ponied up the price for this exhorbantly costly drill bit as a last resort.

It works. What else can I say? A nice, clean, smooth hole with absolutely no damage to the finish of my baby. If it wasn't so expensive I'd give it 5 stars, but it is worth the price anyway.

Like the other reviews: It seems like a lot of money, but the results you get and the piece of mind knowing that there won't be any kind of damage around the the hole is great!
