These Bosch M42 cobalt have been good bits for box store brands and are also part of the $20 off $100 Bosch promotion.
===========
These were also $19.70 this past January with a $5 on page coupon that does not show up in the 3C's price history. At that time, we bought several of the 21pc for similar money from a 3rd party on Amazon with Amazon as the shipper and no problems.

But once a bit from a kit getting dull or damages, that's an indication I need that one more often. Then go out and buy a good one.
Same strategy applies to buy screws, cheap tools (e.g. from Harbor Freight), etc.
For drill bit kit, I have a couple small HSS sets. I found they got dull quickly drilling through the metal roof for gutter guard. That's why I got this kit. I found I use the smaller one more often, so I got a couple Bosch individual ones when Amazon had the sale. Not use the 1/2 inch one in the kit yet, but nice to have it without spending a lot for something I may not use.

The individual bits are generally pure cobalt at a cost of $4-20 a piece for smaller bits.
These re M42 steel alloy (8% cobalt).
Certainly the carbide bits last longer and are better at drilling through hardened metals, but they come at a much greater expense.
A person is probably best deserved by owning several sets. A titanium nitride set for wood and around the home stuff. Something like this M42 set for difficult jobs, and cobalt when drilling through lots of hardened steel.

The only thing holding me back on this set is that it's made in China and I wonder how good their M42 alloying really is.

Sorry, yes I mistakenly put cobalt rather than carbide. I should also add that specialised carbide drill bits and milling bits can go into several hundred dollars a piece.
One thing I CAN say is that this is NOT SLICK. I think I bought my sets for less than $6.
Are the DrillHog brand sets and warranty a scam? Are those even decent quality bits or just another HF quality rebrand?
Struggling to find a 115 piece M42/M35 drill line to commit to, as I need/want to be able to replace broken sizes easily and need the robustness of that material commonly.
Anywhere to get Good advice which 115pc drill sets to purchase? As well as other tooling that needs to be optimized for quality to price?
