Yakamoz 20Pcs 0.3-1.6mm Shank Mini Micro Drill Bit Set Twist Drill DIY Kit Rotary Hand Tools

I needed small drill bits and these work. I am using them to drill the optical fiber lines used for the lights on the Star Trek shuttle.

Quality and size is very good

Used once. worked fine. Drill bits were not in proper order but check before use. I like the flat storage box and the ability to select and dispense the bit for use.

I bought these to clean out and slightly enlarge a gas stove orifice and they worked great. The index box is cheap plastic but for this price, so what?For my propane stove the jets are around 0.85mm and the bits in that range worked great. Finally can get the wok hot enough! Of course, modifying a gas stove is completely dangerous and YOU should never even consider it. A narrow pin-vice is also required for such a task and there are even some for sale WITH drill bits, but I already had a pin vice, so just bits is all I needed.

Zero stars. None of the bits had points; all were misshapen or flat, and couldn’t be used at all for their intended purpose. Extremely disappointed with the quality of the batch I received despite a couple decent reviews.

The drill bit quality was exactly as expected for that price. They are not jobber length and do not have an exact match to diameters they list. Almost knowing this before I ordered, it would not be a big deal. I use them for printed circuit board thru holes of wire (#22 & #24 gauge), pins and various components and precise accuracy is not an issue here. Machinist quality would run as much as $15 a bit so for what I got and my personal use I am quite satisfied. BTW-be prepared to give hem a quick spin across a sanding disc as they are not sharpened properly.

I own a small engine repair shop and these work great for drilling out jets in carburetors.

This small micro bits are very useful for my hobby Building plastic models.The case allows you to slide to the drill bit you need. Small hole opens up tilt the case and bit drops out. A variety of sizes are available for any small project. very well priced. Take care as patience is required for small bits to drill into select materia not to break the bit. Use a light hand pin drill this will assist you in drilling into your material. Thank you for a great product.
