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".

I needed to enlarge the endpin hole on my Martin D-35, but didn't want to use a cheap tool. I chose StewMac based on some other purchases I had made before. Their customer service is unbeatable - professional, friendly, and courteous. After I ordered, they shipped the tool immediately and I had it in only a couple of days. The tool did the job perfectly and my D-35 is now wired for a pickup. Was the tool expensive? Sure it was, but so is any top quality tool. and it worked exactly as I expected. There was no way I was going to trust a cheap tool on my $3,500 guitar. Anyone trying to enlarge the endpin hole with a cheap tool will most likely get cheap results. I trust StewMac for top quality products and exceptional customer service. My advice is always use the right tool for the job and you'll get the results you expect.

I am a long time guitar player, who just now is getting brave enough to try my hand at some repair and install work. I have a Martin 000-15 that I have long wanted to put a pickup in, and recently decided to try it myself. I was terrified of drilling the endpin out, so I purchased the StewMac endpin reamer to ensure success. Yes, it’s a bit pricey, but it was about the cost of having someone else do the pickup install, and having other guitars I want to do future pickup installs on, I think it was totally worth it.

In terms of its use, widening the endpin hole was a breeze (remember too I have NEVER done this before). I quickly had a beautifully centered, symmetrical, and clean hole to install my pickup jack. Not only does my Martin now have a pickup, but I was able to learn a new skill and do so with the confidence that I wouldn’t make a mess of my guitar. This endpin reamer proves the old adage true that you should have the right tools for the job! Thanks StewMac!

Used to pay several hundred to have endin jacks in my acoustic guitars. Bought the Reamer Bit and the last two I installed myself went smooth as silk. DO NOT try to drill the holes with a regular bit. You WILL chip the borders of the hole. This bit follows the endpin strap button hole and then finishes the hole to exactly 1/2'. Use painter's tape to help keep from scaring Bout finish when you are tightening up new 1/4' jack assembly. You WILL be glad you bought this bit!

I've used one for many years, it's still sharp and cuts clean. This is only tool you need to drill out a tail block for an endpin jack. It is very accurate and won't damage the finish. We include the EndPin Jack Reamer in the tool kits we provide for our students at The Guitar Services Workshop, it's the perfect tool to do the job right!

Another example of a specialty tool that makes a tricky job much easier. Even if you only work on your own instruments, this tool pays for itself by giving you the right result first time every time.

Perfect Tool for the Job

I own nine different custom luthier-made diatonic autoharps and needed to drill a hole in the bodies to accept 1/4-inch flush-mount endpin jacks (Switchcraft #151) for connecting to magnetic pickups. The body frames are, for the most part, constructed of 1 1/2 inch (approx) laminated hard rock maple pinblock, and I wondered how difficult it would be to make it all the way through without really ugly results or over-heating the bit. After drilling a pilot hole using a standard 1/4-inch bit, I used the Endpin Jack Reamer to gradually widen the hole. The result was perfect. There was no damage to the exterior veneer and finish, and the interior of the final hole was straight and smooth. Extraordinarily good results. Well worth the investment.

I was getting ready to install a pickup in my Martin D-35, and didn't want any problems with the installation. I was not inclined to use a drill bit to enlarge the endpin hole, so I bought this reamer, which was exactly the right tool, and it worked flawlessly.

I languished so hard over this purchase thinking if I am just careful with a 1/2" drill... Broke down got one, used it to add electronics to a 000-15m and I am so Happy I reamed the endpin hole using this rather than drilling. This tool is very sharp cutting through wood like butter. Electric jack holes end up snug and tight fitting as can be. no chatter, chipping, splintering. worth it. now all my buds and bandmates are after me to add piezo to their acoustics. Keep the tool sharp storing in box while not in use.
