KAISH Violin Viola Peg Hole Reamer for 3/4 4/4 Violin 1:26 Taper with Wood Handle Violin Luthier Tool

Tried it so far on two of my violins, and the taper angle was perfect for both. Cuts well on the wood

I used this tool to ream Ukulele tuning machine holes in the peghead. I drilled out the backside of the peghead with a drill for the correct size and then reamed the front of the peghead to size. I installed Gotoh Planetary 4:1 gears for the front and back of the gear is a different size which is what I would expect. This reamer worked perfectly for the job, it reamed smoothly and cut the wood quite easily.

Works fine - only slight turning needed.

I purchased this reamer to install end pins on two acoustic guitars I recently built. The pins have a 1:30 taper and the tapered hole left by this reamer mated up perfectly for a snug fit on both of them. Similar reamers from luthier supply companies go for twice the price, so this was a really good value.

The taper on this reamer is 1:26, not 1:30 as advertised. It's stamped "1:26", and I measured it to 1:26 with a caliper.

Good price compared to 'professional' tools and works just as well. I use it to size peg holes in violins for fitting new pegs.

The planetary tuners I bought (Gotoh) for my ukulele need a 10 mm hole, slightly larger than the one for the existing worm-gear tuners. This reamer worked extremely well, cutting faster than I expected, and leaving nice clean, smooth holes. I may only need this tool a couple times in my lifetime, but it's a keeper!
