This is one of my watch items. Hoping to get a bargain this cyber week. It's been $30 at Amz for at least the last 6 mos. So this "44% discount" is 15% in the real world. Not horrible but definitely not a cyber week barn burner.
Forstner bits produce a cleaner hole with less tearout on the exiting side if you drill all the way through. Forstner bits are also better for drilling holes that don't go all the way through the piece and will leave you with a flat bottom in the hole. A spade bit will produce more tearout and if you're only drilling a partial hole you'll have a smaller hole in the middle from the center point.
Best price since May 2020,(was $23.98 so $1.50 in inflation is not bad) this item typically goes for $30-$45. Data from CCC

Thanks, OP.

I bought a $10 set of forstner bits from harbor freight, with the intent of using them until they quickly wore out, and replacing them with better ones along the way, but they're such hot garbage that I'm tossing them out as soon as these arrive

Harbor freight is a hit or miss. I've done similarly and at times it felt that I should've put the money I spent at HF towards the better item. Thanks for your input, I'll just skip HF for this item.

Wow these have been in my cart for years at $45. Can't believe the price budged.

....edit....I've been watching the 14-piece set.

Surely not your Amazon cart, because Keepa proves that the guy above you is right, sat @ $30 since June. This deal rates a solid "okay".

I bought their forstner bits from their Hercules brand and they are good and have carbide tips

Combined with Amex deal to get an extra 40% off, so paid about $15. That said, bought an 8 piece Ryobi set for $22 in 2019 I haven't used much, but couldn't help myself…

Machinist by trade. Do yourself a favor and spend a few extra bones on *anything* with carbide teeth. They essentially will last you 10× longer and could actually be re-sharpened.

You'll likely not need another set unless you're drilling holes daily or don't take care of them.

E: That amex offer above 👆 if you're eligible, I would bite on these. Otherwise, get carbide.

Got these in June 2020 for $23.98, have used them several times and they are great. (To be fair I have limited experience with finish wood working, plenty with framing)
It is really nice to have these and a drill press when the need arises.

Good advice above. I'd also add that spade bits can drain your battery very quickly and get much hotter than you expect, because the cutting edges are really bad angles, so the drill and the bit have to do a lot more work as compared to a Forstner bit.

Since getting my forstner bits, I've only used my spade bits to drill through material that was longer than my forstner bits (and I didn't want to drill from the other side and misalign the holes).
