This shit is not real metal. I tried my brand nee set of 6pc damage screw extractor for the first time to see how good it was and the “metal literally crumbled into pieces as it ate the bit away. I am highly disappointed and pissed.
The chain is fine...but I ordered the wrong size. Nine links of the chain I ordered equals six of the size I wanted. My error...
How can I straighten out the springs? I can't use them coil uo as is.
I was surprised these performed so well on my granite counter top considering the price! I thought I would go through all 5 bits but I successfully drilled through using only one bit. And it was sharp from start to finish!
I used plenty of water to lubricate, and took a few breaks to let the bit cool down.
