T Handle Taper Reamer Set 3-13mm(1/8''-1/2'') & 5-16mm(½"-5/8") Bridge Pin Hole Hand Held Tapered Reamers 6 Fluted Chamfer Reaming Guitar Woodworker Luthier Tool (2 Pieces)

Product works as intended. Haven’t had any issues and I’ve used it a few times to expand the holes for installing new tuning pegs on my guitars.

The two size reamers cover the most common bridge repair jobs. Be careful to know which to use. If using your old pins fit the two reamers to your old bridge to determine the right one. Go slowly and find pins periodically. I was worried that these were so cheap compared to professional models that they wouldn’t work or worse would ruin the bridge. Far from it, they were high quality steel and a sharp cutting blade. For non professional occasional use the are more than good enough. I’d recommend!

These work as intended. Decent for the spend. Angles are good for 3° and 5° taper for bridge pins. They could cut a tad cleaner but do the job. Also the handles could benefit from a taper for a friction fit.

Works perfectly when needing a slightly bigger hole upgrading volume and tone potentiometers on a guitar.

This tool is AWESOME.. Used it on my acoustic guitar for pin holes.. And even used it for a washer hole up top.

These work quite well on plastic and aluminum that I used them on.

Easy to use and does a great job! Just be sure to make sure you know what size you need exactly before you order

Solid tools. Used for guitar repair and service. This set I bought for the larger size, although I will soon also need the smaller sized tool. I needed to enlarge holes in a peg head for new tuners. Went from 12mm to 14mm. Did the job. Maybe it could have been a bit sharper, but I was cutting hard maple. Took longer and needed more force than I anticipated, but made clean cuts and did not chip out the finish at all.
