Review on Mxfans Golden Plating Copper Spring by Ted Boone
Good product but the specs are wrong?
I bought 1mm drill because the specification says 0.5mm tip, 1mm shank and 2mm tip width. It is impossible to insert them into a hole with a diameter of 1 mm. They fit freely in the 1/6" drilled holes so I expect the shank to actually be 1.5mm wide. Otherwise a good product.
Pros
- Made of gold-plated copper.
Cons
- Almost everything is fine
