Drill Bits - What is best?

   / Drill Bits - What is best? #21  
honestly, I tried a few- I find that the best drill bits are the sharp ones that can drill a few deep holes in steel. If it won't even with frequent sharpening then its crap bits. you just need to learn the art of sharpening them yourselves. you tube has a few videos on this.
