Speedy most cutlery isn't premium SS. I got some that rusts or pits just being in water a few days. At least they still cleanup with steel wool.
Mowerfreak, As for being hard on drills bits depends the quality of your HS bits. A few years I brought a set HS drill from Lowe's that I couldn't even drill a single hole the angle iron that makes up bed rails without dulling them. So I went to my local Fastenal store pickup a couple premium HS bits for testing. With those I was able to drill nearly 20 one inch deep holes in cast iron before they dulled. Using a low speed drill helps too as I no longer burn the bits. If thing too much for HS bits you could always go to Carbide tip bits as I do when break off an extractor or trying to drill heat harden exhaust screws. Even though those Fastenal bit are 6X the price it well worth just not having to drive 60 miles just to get a handful of the cheap bits.
Now as Speedy does I re-sharpen my bits though I don't hand sharpen but I don't know if Speedy does but it can be done just as accurate as machine sharpen ones. I use a Drill Doctor bit sharper that has a diamond wheel.So nice not need to buy multiple bits or make a run to the store just because I dulled a bit. I do have few that I going to need to replace now but that is because they are getting too short.
And if you sharpen a carbide tipped masonry drill bit to give a cutting edge similar to a normal steel bit you can drill through a car leaf spring or through a mower bar without too many problems. I was quite surprised when I tried it
Yes they work very well here too. Just not as precise as regular twist bits but they do have their uses in our repairs. They just don't work very well on the even harder steels.
This is where you just need ones that can handle Rockwell C70 specs. Those bits are very pricey for limited use. I just check on a 17/64 bit and it is over 45 usd before the shipping charges but you got to have it you don't have much of a choice so sometimes it is better just to get the replacement part.
I do have a project that I need to test the material to if one those masonry carbide tip cut the metal as a regular HS bit only dulls without leaving much more than an impression of the point in my drill press. If cuts then I can a cheaper 17/64 Carbide twist bit. It either get the bit so I can install a $.50 bushing or get the $15 bushings. I hope it works as I like to offer the guides in the finish reamer size to other techs here in the US for doing the 1/4 valve guide as the current guide only work with the counter bore reamer and is quite sloppy for the finish reamer.
BTW Speedy you can destroy all the Sporks that you want. To me they were and are a very useless unless you like wearing your soup instead of eating it. Somebody came up with them that was too cheap to have both a fork and a spoon.
Just watched the infomercial on Does it all Drill Bits from Renavator........

Speedy I don't know how they get the bits to do what they do on TV but it is like the age old saying ," if it seems too good to be true, it probably is"
The adds should be withdrawn. The TV station is helping in the false advertising and should take some of the blame......
I might make a call to consumer affairs and have a talk.......

There was another scam earlier this year that kept showing up on the ebay and Gumtree home pages for a TV ariel and amplifier that was supposed to perform miracles. Last time I looked there was 29 pages of complaints to Paypal because Paypal continued to allow the transactions to go through when they were well aware it was a scam. Paypal ended up picking up the tab because obviously the scammers had done a runner
