GYROS 12 PCS #80 Micro Drill Bit Set – Small Drill Bits for Jewelry, Plastic, Resin, & Soft Metal – High-Speed Steel Wire Gauge Mini Twist Drill Bit Set for Pin Vise Hand Drill & Rotary Tool

You had better have good eyes as these are tiny .... BUT worked for what I wanted, CRF50f carb that the pilot jet was blocked nothing would clean it -- ultrasonic various products using carb cleaning tools only would bent, the jet is part off the carb and not available on this model -- so i removed the jet and jet tip the part that was blocked like on a Forum[...] slowly drilled by hand the blockage with  Gyros 45-01801 Mini Adaptor Chuck, 0-Inch to 039-Inch Capacity (For Dremel Type Tools)  , the #80 bit is smaller then the #38 Honda pilot jet ... So if your pilot jet is blocked and soaking does not work this drill bit will.

These drill bit are excellent, just make sure that the mandrel you buy for these is of good quality. I didn't do my homework on the mandrel and then struggled for most of my day. However, the drill bits faired really well to my ideas on how to make it work.

Just what I needed to unclog the drip irrigation tubing (holes every 12 inches). Broke two or three bits before got the hang of it. Recommended. If you found this review helpful please click on YES below.

These bits are tiny. So small you can barely see them, but they do get the job done. As you can imagine, they are easily broken, as they are so small. You must use extreme care in using them to not apply too much pressure and snap or damage them. That being said, they are as advertised, and will help you get those small jobs done. I use them to unclog the extruder on my Makerbot 3d printer.

I suddenly found myself needing a replacement for a tiny drill bit for my model-building. This pack came up in a search and the price seemed good. Considering that I didn't want to be without if one broke while I was working late at night, this multi-pack is perfect for me.

3 of the 10 bits were dull and didn't cut. For the price it was okay.

Clean, cuts well and durable from my use so far.

What I wanted. Several bits. They are small and easily broken.

A+
