I've gained a few that way on larger jobs , my very first paslode ( first fix ) came that way many moons ago on a huge studding job .I would be in the former camp of a few drill bits. Tbh id have written the cost of a cheap mag drill into the price of the job.
A lot of my tools have been paid for by customers.

was watching some builders use a 5 inch dewalt angle grinder brand new on hire to cut out a large 3/4 steel gusset with a grinding disk they were forcing it in and slowing it right down 
i went and told them not to press on keep the speed up and run it back and forth . just took no notice and carried on in 5 minutes they burnt it out and it was stinking i just said serves you right some people cant be helped

For a load of 12mm holes on site these days I'd price in a HMT turbotip one for every 20 holes, probably get 50ish holes out of them and pocket the rest.
Why that over conventional drills? Speed and convenience. Could do 3 holes with an impact gun in the time it takes anyone else to do one.

Those are the dogs. I have a job profiling plate for someone. It’s a recurring job so worth putting a bit of money into to streamline it at my end. I use the plasma to do the outside and spot the hole centres, then use a HMT tool to put the holes in. It’s a nicer job.
For reference. They don’t like reaming out plasma dross. That will kill them and that’s direct from the tech bod I rang at HMT.

It also happens on the TV..lads drilling steel too fast a speed and then you see the blue colour of death on the bits...I have never met anyone in the building trade who can make a metal drill bit survive longer than 5 holes

I have to say, watching a gobshite site manager who couldn’t wait 5 minutes for us to finish our brew climb 10 foot up a ladder and lean on the mag drill like it owed him money, causing it to pop off, smack him in the face on the way down and lead to him lying in a crumpled heap on the blokes lawn was one of my better days in that job

It’s the same manager who at the ripe age of 49 demanded an apology from me because he spent all day stood behind me watching me weld and got a flash in both eyes. He rang the company owner at 3am quite literally sobbing because he thought he’d gone blind. Apparently I should have told him that could happen. Taught him about being in the way

That was very unfair of you 
When I first started tigging beer barrels the older blokes thought it hugely funny to nip in my booth at bait or dinner time and switch on the delay..... and have a good snigger when I got flashed didn't take long to catch on ..... revenge was sweet I used to rub dry caustic powder round the inside of the barrels they were putting the tops on blew holes eveywhere and took em ages to clean them up

Be interesting to see a comparison of them , they are only claiming 4x speed vs a roll formed drill bit , so doesn't sound too out of the realm of possibility. I wonder how they compare to the split grind bits which have a much smaller chissle section in the middle of the grind.
All the ones that look like that near a pals drill press have the little protrusion melted off, not sure what brand they are, I will check the shank next time I'm there
Can you sharpen them ?

Just realised I need 6.4mm or 1/4" for rivets - they don't seem to do that size
You sure? 6.4mm rivets typically need a 6.5mm drill. eg https://www.part-on.co.uk/product/pop-rivets-6-4-aluminium-steel-domed-head-rivet-fasteners/
I did rescue a few but most had gone blue they are never any good after being that hot.
