GMTOOLS 13Pcs Cobalt Drill Bits Set, M35 HSS 135 Degree Tip, Twist Jobber Length Drill Bit Kit for Hardened Metal, Cast Iron, Stainless Steel, Plastic and Wood with Storage Case 1/16"-1/4"

Q: These work pretty well as a general bit set for drilling most metals? Is applying oil generally needed on a surface when drilling?

While in trade school many decades ago, they taught us to use cooling for chisels and drill bits, I did dry drilling many times throughout the years, it works; however, cooling will extend the life of the drill bit for sure. One online resource said the following: If you don't cool, the material will harden and the drilling will get tougher. With special cutting oil, you cool both the material and the drill. This makes the drilling faster and more effective. The drill bits also last longer, because they stay sharp. Hope that this answers your question.

Q: Are cobalt bits better than titanium bits?

Yes. Cobalt is harder and can drill through harder materials such as stainless steel.

Q: Is the entire bit comprised of the M35 5% cobalt alloy or is the high cobalt steel just on the surfaces?

The entire bit is comprised of the M35 5% cobalt alloy. That is why they should last longer.

Q: Will this fit in a standard household drill?

Our goal is to provide our customers with the highest quality and service. Yes this M35 HSS Drill Bit will fit just be mindful that this is a straight shank bit.
