UFS-061B Improved Spin Drill

This is a mashup of two clever designs.

Hand beater handle, https://www.thingiverse.com/thing:4290265

and

Handle for 1/4 inch hex bits,https://www.thingiverse.com/thing:4308369

The hand beater handle came out first. I downloaded the design right away. Not because I needed a replacement handle for my egg beater, but it was just so well designed for functionality and for printing. I just needed to find something else to attach to the handle.

Then I saw this handle for hex bits. It was a good match up.

I tried a couple of designs based on these two parts, but I’ve only printed one.

After printing the design, I went to Lowes and bought this inexpensive set of hex drill bits. https://www.lowes.com/pd/Kobalt-21-Piece-Titanium-Coated-HSS-Twist-Drill-Bit-Set/1002680600 It is a good combination.

It works ok. The hex bit holder part is loose. It needs to be shrunk down to more tightly hold the bit.

Using it as a drill puts a lot of side load as you turn the handle.
