Need to buy a reamer for the pegholes on my Martin OM kit.
It appears their are 3 and 5 degree reamers.
Anyone know what the proper reamer angle is for a Martin peghole?
Also, these things are not cheap ( especially if you shop at Stewmac )
Philadelphia Luthiers has one that isn't too bad ( $47 )
I assume the cheaper ones on Amazon aren't the correct angle for a peghole.

took for tapered reamers at any commercial tool like McMaster Carr you can find them

What type of tuners are you installing?
I've never used a tapered reamer on a peghead. Some tuners can use a stepped down hole, but even that really isn't necessary in my humble opinion.
Reamer for an end pin......yes! For tuners?????
Must be something I'm not aware of.

By pegholes, do you mean bridge pins? All of the tuners I've installed only required straight drilling. As far as the bridge pins, I use a 5 degree reamer. Here's a link:

The Geetargizmo in my first post, is definitely 5°. It's what I use.
I think this is too. You can order a set of 2, with slightly different angles, too. I'm assuming they're 3 and 5, but I won't swear to it.

There are old tuners of yesteryear that were slightly tapered. Stewmac sells a reamer for these zebras. I don't bother with it. 99.999% of the time the old buggers are very hard to use, so I end up replacing with modern vintage tuners and I keep the old ones with the guitar.

I bought a stepped reamer made for the purpose by Stew Mac for Grover ukulele tuners. It is pricey for occasional use but it does a very clean job. I also have an end pin reamer from Philadelphia Luthiers and it is made offshore but nice quality. Bruce W.

I drill the smaller hole, then mark the larger bit for depth and drill to that depth. So I just use 2 drill bits.

I've come awfully close by (1) drilling an 8mm hole for the tuner then (2) using a metric stepped drill (conveniently stepped from 8mm), the centering bore and 10mm for the counterbore, drilling till the 10mm step is fully engaged. Done. A finished tuner post hole with 8mm and 10mm bores. No thinking required, which I find particularly useful in my case.


As for bridge pins, I found a 'General' brand tapered reamer, a routine hardware store tool, works just fine. It works just fine, too, for a luthier friend on his custom builds. Nits may be picked, but this reamer goes a long way to getting good results.

Sorry. I'm an idiot.
I wrote Peghole when I should have written Bridge Pin.
Some of you figured out anyway.
Got some good feedback on reamers for bridge pin holes even with my mistake.

Thanks
Sorry for the confusion.
