GYROS 20 PCS Mini Twist Drill Bit Set #61 to #80 w/Dome Storage Case, Carbon Steel Wire Gauge Micro Drill Bits for Jewelry, Plastic, & Soft Metal | Small Drill Bits for Pin Vise & Rotary Tool

I love this! Great value for the money, size and versatility. They are very durable as you do use them for small motors you still have to be careful. All the micro bits are labeled in a cool container that you can easily see and read each size. I love this and it would be a perfect gift for anyone who works on small motors and they just might work on your stuff for free after you give them one of these! They are very precise and a good grip is needed or get a tool to put these into is what I would recommend. I will be ordering me one of those vice pens. I received the product quickly and in new condition as described. You can't go wrong with one of these.

This GYROS Mini Twist Drill Bit Set is a total game-changer for my toy restoration and building projects! The range from #61 to #80 covers every tiny hole size I need, and they work perfectly with my Tamiya Pin Vise. The bits are sharp, precise, and durable — they handle plastic and soft metal with ease. I also love the dome storage case; it keeps everything neatly organized and easy to grab when I’m working on detailed repairs. Highly recommend for hobbyists, model makers, or anyone doing precision work!

Thanks. I got these to increase a carb jet diameter on a 1956 Johnson 3 horse outboard. Looks like they are smaller than my jet ha ha, but I like them very much. I am sure they will come in handy someday.

I got these because I needed the smallest one to clean out the fuel jet on a lawnmower and it worked perfectly. All the drills are captured by the dome and additionally have a rubber ban so they don't all fall out when you try to take out just 1.

Hard to grab so I use small needle nose plyer to grab them. You should order hand held holder to drill jets in your small engine carburetors by hand

Bought these to use as a measuring device for small engine jet sizes. They worked perfect

This ia a very nice kit. I purchased it mainly for cleaning and enlarging carburetor jets for small engines. The fact that they stand up vertically in there own accurately sized holes is really nice for finding the right size you need. They are sharpened well so with patience there is no problem drilling a hole a little oversize. When I received the kit two of the bits were knocked out of their holes and one bit was broken, I assume from rough handling by someone in the shipping process. I reached out to customer service at Gyros and the rep sent two bits out pronto. Even though I may never use that particular bit I felt I should have a complete set. Kudos to customer service. I have other micro bits that don't compare to the sharpness and accuracy of these. Using a digital caliper or micrometer to check sizing will tell the story with cheaper bits.

These drill bits are perfect for carburetor jet work. Being a machinist for over 35 years the tolerance of each drill is dead nuts, as marked in drill bit holder case. I used a micrometer to measure each one. Avoid this set for $7.99 which 7 drill bits were the same size in both cases..0.3-1.6 mm Micro Mini Drill Bit Set Tiny Drill Bits Small Shank Full-Ground HSS Twist Drill High Speed Steel Boards Tiny Drill Bits for Dill (40 Pieces)

An excellent drill set in a compact holder. No more losing drills. Service was quick with good pricing.

They work great, a little hard to handle because they are so small. I found it funny that gasoline will eat the plastic container considering these tools are for carb cleaning

Absolutely want I needed for making holes in turrets or machines gun barrels when building plastic models. Be very careful with the smaller bits as they are fragile.

Works as described

I purchased these to use as Motorcycle carb jet cleaners. Work excellent for that purpose. Will purchase a pin vise to use with them shortly. Container keeps them together and organized. I used a piece of electrical tape to lock the cap to the base in the event that they get knocked over or off of a desk.
