Accurate holes for a better fit! Our special wooden-handled steel reamers properly taper the holes for bridge pins or endpins.

These reamers are semi-fluted, to help keep the holes round, and are available in two sizes.

The 3-degree reamer tapers from approximately .312" to .150", with 3" cutting length, and is suitable for many bridge pins from Gibson and Gurian.

The 5-degree reamer tapers from approximately .312" to .135", with 2" cutting length. It works for our vintage-style pins, as well as modern Martin bridge pins.

Bridge pin reamer

By Don Shreffler from Council Bluffs, Iowa
(Customer's Reviews) Friday, May 11, 2012

I don't write a lot of reviews, but I discovered a couple of techniques which may be of some value to others, so here goes... first, this reamer was a little pricey. The five stars are for how well it works, not the price. That said... I read others' warnings about going too fast and finding out the hole is now oversized. I can't emphasize the importance of this enough. So try this - loosely place the reamer in the hole and start turning it, letting the presence and weight of the tool do the work. You may find you have to add a little force to it, but try this first and see if it works. I did this on a bridge re-glue and it worked well, without using any force at all. Second, if you find out that you've gone a little too far, and you should be checking the fit OFTEN, wet a Q-tip and run it into the hole a couple of times. The wood will absorb a little moisture and swell - when it dries, you might have regained a snug fit. I did. Pretty lengthy review for the first time!

Very helpful tool

By JHW from Lexington, KY

I needed this to get my bridgepins to fit perfectly on a replacement bridge. It seems there was some small variance in the diameter of the bridge holes which left some of the pins higher than others. Couldn't do the job right without this tool. Be careful though, the reamer is very, very sharp and you can easily ream out too much wood or cut yourself.

A Small Word of Caution

By Patterson from Fremont, MI
(Customer's Reviews) Wednesday, January 04, 2012

Bought this tool so that I could use the 5 degree bone pins on my '78 12 string that had seen too many string changes. I can't really add much new to the other reviews - they are all telling the truth - except one caution: a little reaming goes a long way. No more than a quarter turn at a time. I almost blew it on the first pin hole!

Essential Tools!

Great quality! Couldn't do with out this reamer!

Proper tool for the job.

By David Deaton from Arkansas

Decided to properly fit the bridge pins on my Martin myself rather that hiring it done. Used it on 3 guitars so far. High quality. May be a tad expensive for a one time use, but in my case it has more than paid for itself. Great pleasure in servicing my own instruments. Excellent service from Stewmac.

Makes a Perfect fit for Bridge Pins

By Adams Guitars from Wisconsin

Due to the price, I debated about buying this tool for quite a while before buying it. Now that I have it and the bridge pins fit perfectly, I do recommend having one.

Pricey, but does the job.

Does your Martin guitar have bridge pins that sit a mile in the air? Then you need this tool to finish the job that Martin didn't. It's not cheap, but it does the job perfectly, and that's worth a lot. I used this tool along with Stew-Mac's slotting saws to slot the bridge and install Stew-Mac ebony bridge pins in my Martin D-18V.

After seeing my guitar, all my jamming buddies want me to do their guitars, too.

A lot of money but you can feel the quality, accurate 5 degree too.

Bridge Pin Hole Reamer

By Andrey from Russia Urals Mountains region
(Customer's Reviews) Wednesday, December 08, 2010

These reamers are fine tools! It is possible to have from them an additional benefit.

For example to insert qualitatively any lonely file into a handle. Process them an input in handle preparation. Use epoxy for file fixing.
On a photo ready handles are painted by a grey waterproof paint.
