The titanium is just a coating.... it helps a little with chip removal when dry drilling (no oil), but not the actual cutting. If you look at the cutting tip, it is gone almost immediately. The main upgrade for the consumer would be cobalt 35 and then 42 as the better.
The 14 piece [amazon.com] is also on sale if you don't need a larger set.
The OP set has several duplicates of smaller bits that perhaps some may find useful. For me, the savings is in the larger bits; the 5/16", 3/8" and especially the 1/2" that may cost the $10 at a box store [lowes.com] by itself.
That said, I don't care for the reduced shank on the larger... which is where they break when drilling thicker steel and they catch. Most every drill today seems to have a 1/2" chuck, so no reason to reduce the shank to then grind three flats. Bosch [amazon.com] does similar with some of their sets.... but their Cobalt 42 bits are good bits.
It is not the end of the world, as you just grind the break flat and have a shorter drill bit.

Just buy the $10 HF 29pc special for Disposable bits, as they tend to hold up better than the Box Store brands.
And, if you get tired of junky bits, step it up to WoodOwl (for wood obviously) and Nordic/Viking (for metal and wood.) It's nice to have a big set, but it's pricey. So, buy the 3/6/12pc envelopes from Viking, in the sizes you'll use most, and once you try them, you'll see there is a vast difference.

I watched Todd on Project Farm do a comparison and having used, these DeWalt bits are decent bits. Actually, one of the few 'bits' they make that are decent for the sale price money, as their impact drive bits have been kind of junk in comparison to other box store brands like the better Makita or Milwaukee impact drive bits.
Harbor Freight makes some decent cobalt drill bits, but their best is only M35. I have bought their 115pc sets mainly for the Index boxes, but the M35 cobalt for around $100 was decent and the 115 pc black HSS set for like $30 with a coupon was worth the money after sharpening a few of them. I was pretty certain the Index was worth the $30 as I needed it next to a new drill press.
Each winter, we have a few gallons of used bits to sharpen. I did buy a DrillDoctor 750x a few years ago and for 135 split point drill bits, it does a good job if you will use the finer diamond grit wheel to finish and don't get them too hot... a water coolant would be awesome. With the ability to hand sharpen, you know if it is sharp or not, but be careful not to mess with the tempering. Don't rush it and it works well.
Personally, I like Triumph or Hanson because we have been a dealer for a couple decades and wholesale they are reasonable with decent quality. For certain, the value in the OP is the larger bits, but watch for a Bosch M42 cobalt deal that comes around once in awhile.

Sold locally by Fastenal, Viking makes good bits for a price, but if precision size is important, you might want to buy their SP bits that tighten the tolerance and chosen from those manufactured. Perhaps you can guess where those that are outside that tolerance go, but granted, also for less money and within the tolerances of many imports.
When it comes to Viking specifications, they always quote NAS 907B which is quite vague as far as materials used. In fact, 907B includes HSS. Granted, Viking does say "Premium Hi-Molybdenum Steel" (no percentage) and while they are quality bits, I am not sure they are worth 10 times as much as with their Ultra Bor Super Premium (nitro-carburize finished).
Those are government prices... lol
Also know they do not manufacture everything they sell and some items are not made in the USA. I kind of expect some of their Index boxes fall into that category because some are junk.
Drill bits are typically disposable items, but some sellers like Matco, Drill Hog, etc., will replace if your break one. I used to think it was because of the premium price charged, but even higher premium priced like Viking states drill bits are disposable and will not be replaced.
Breakage is one thing and dull is another. It is like many saw blades are cheap enough that it is not affordable to hire them resharpened. Many drill bits fall into same category. But, if one would learn to resharpen, they are no longer always disposable.
PS: Not sure who the insecure clown leaving negatives without commenting is, but they must have a miserable life.
since i bought a Spyder Mach Blue set... haven't needed any other.
$10 for set vs $10 for a single bit. I'll take the cheap set at Day- as I'll get several uses out of each bit until it breaks or dulls unless I'm drilling through metal.
Oh and i have never bought any special lubricant for drilling. Wd40 and even vegetable oil works well enough, as long as you clean it off when done. I don't drill through metal often.
