Reamer Handles: 3-12mm range

If you're using drill bits to size your holes, please know that there's an easier way: Reamers. These tools are specially made to size holes to an exact diameter, whereas drills get you “close”. Reamers also have the advantage that they don't draw themselves into the work, so you don't have to fight the tool or risk cracking your project due to a drill bit suddenly grabbing.

This Reamer Handle set fits the reamers listed below on Amazon; 3-12mm range.

I got a set of cheap reamers on Amazon, then realized I needed a handle to use them. I have a couple T-handles for taps, but they're not able to hold the full set of reamers I have and it's mildly annoying to store the bare reamers and need to attach the handle for a quick ream job. So, I spent a few hours taking careful measurements and designing these handles. Now, the reamers are as easy to use as a screwdriver, and absolutely PLOW through plastic.

These are the reamers I use: https://www.amazon.com/dp/B09C8P6N36

You might be able to find others that fit, but I can only guarantee this listing will fit correctly.

After you attach the handles to the reamers, they can stay on permanently. You will probably want some method of storage, so I made this reamer rack: https://makerworld.com/en/models/2764478-reamer-rack
