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".

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.

A long tine ago I learned that you cannot ream the end pin hole with a drill bit or file and have it both straight and without the horror of chipping the edge of the hole so that it is visible to the player upon inspection. This tool is easy to use, is really sharp and makes a strait cut every time.

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.

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.
