Strongarm 2 any size carbide drill
These drills aggressively cut through all the hard plate I have encountered, excluding Relsom and matrix plate and other types of similar hard plate. When the Strongarm 1 drill bit starts to struggle the Strongarm 2 drill bit seems to melt a whole right through with less effort. If you drill safes I would recommend stocking up on the Strongarm 2 in all the sizes available.

Great bit.
After a few seconds of drilling it really starts cutting into the hardplate.
