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".

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.

Tuners too - safe and fast

Don't do the clumsy hand reamer for tuners - this one does it in seconds - just be sure you mark your depth with a piece of tape.

Reaming is a breeze

As the owner of a small music store, I have been using drill bits to ream out the hole for an end pin jack. I don't know how I lived without it. I just chucked into a 3/8 cordless drill and in less than 5 minites I had the perfect hole for the end pin jack.

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.

Works Perfectly

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!

what a great piece of kit!

I've only just replaced one of these that I've for something like 20 years. it made a vast number of holes in various instruments and served me brilliantly. it was a great pleasure to get a brand new one after all these years and find that it's exactly the same as the old one! well done, guys! it wasn't broke and you didn't fix it ....... :-)

Amazing End Pin Reamer

WOW, talk about getting the right tool for the job. After using this on two guitars, I can't imagine doing it any other way. The tapered reamer and then the straight part is so perfect. Very professional.
