T Tulead Ceramic Screwdriver Adjusting Screwdriver Stepper Dirvers Screwdriver Bit 1.3mm,1.8mm,2.6mm,2mm

They are very cheaply made. Mine were all crooked and too short to be used in some applications such as adjusting cassette deck motor speed. Will be retuning them.

Started using a 3-D printer and expect to have to make some adjustments with it powered up sooner or later. Went ahead and bought these to be sure I don't get tempted to use a regular one "Just this once" and short something out.Probably end up buying one since they are slow to print and tying up the one I am using for a day or two is out of the question. Then I am positive I will have to adjust the one I bought during setting it up.

I used these to calibrate the motor on my CT-F9191 Pioneer cassette deck! The slotted one worked perfectly with no chance of getting shocked or worse running the motor! ; )

These seem good for what they are. They however feel somewhat fragile and cheaply manufactured. I'm worried that it will snap if I'm not careful but otherwise they worked for a one time need and will be safely stored incase I ever need them again. I would reccomend these for a hobbyis, but would suggest getting a professional set for more frequent use.

If you need a non inductive screw driver set, these are great. It is softer than steel, so really only for tuning inductors, to my knowledge. But it is still amazing that a ceramic can be this hard. Zirconium is a fantastic element, I am a fan.

I like these for radio work , great for if transformers. Pretty sturdy tips for radio work

one of the screw drivers was not symetrical. definately harder to use one critical RF adjustments.

They are ceramic. They are not straight. The do work. They aren’t very good.

Product is ok, but the top part doesn’t freely spin on 3 of the 4 drivers I received. There is quite a bit of friction while trying to turn it, making it not very useful in some instances. Drivers also shipped in a bag, no protective case.
