I don't know where they're made these days. But Cleveland Twist Drill and Chicago Latrobe products are frequently found around places that need quality metalworking tools.
A quality 115 piece number, letter, and fractional set made by either of those manufacturers will set you back north of $300,...probably significantly more of they contain 8% cobalt.
I don't know for sure. I haven't checked prices in a while.

This turned into a " my drill is longer than you drill" pages ago. And they still call them bits. Ha Ha Ha Perhaps, but my girth is rather impressive . ![[Linked Image from i.imgur.com]](https://i.imgur.com/aZSk2jm.jpg) Flashback to spuddin’ in.

A drill was waiting on a sidewalk
A car pulled over and the driver asked : how much for a good time?
The drill : sorry I don't screwdrivers.
I had to sit through a 3-hour lecture about drills.
It's was just boring.
My job is to drill holes in things and then connect them together.
At first it's boring, but later on, it's riveting!

High Noon,
What kind of things are you drilling?
Is it a fabrication or repair shop?
How long have you been working there?
Is it , a job shop?
I like to do my hunting BEFORE I pull the trigger!

wheelnut: I need bits that will drill through hardened steel, stainless and mild steel. These bits are not for professional use, they are for my own personal use at the home and ranch and they will not be used daily. I just need bits that will work when I need them to - I'm tired of using schitty bits that don't work worth a crap in various types of steels.

High Noon I would check with Graingers it is a big Catalog for industrial tools.
Brownells has a big catalog full of gunsmithing tools and they handle drills and taps for small holes.
When you said hand held that told me you do not need carbide. If you say stainless there are about
30 different kinds of alloys and I was a CNC machinist and we always used water based coolants unless it was heat treated then we used cutting oil. Very messy and noisy.

What I am trying to say is that you will need different tools for different materials.
Save your cheap Chinese drills for wood or mild steel. Break out your good stuff for stainless steel or other alloys like inconel. The harder the material is the shorter the tool life will be. Sometimes you'll
need to change tools in the middle of a hole.

Slow down drilling. More pressure is better.
Use a water soluble oil. Cutting oil doesn’t cool like the water does.
Heat is your enemy.
Cobalt drills are maybe 3 points harder on RC than regular HSS. Worth it.
The titanium nitrate coating only helps if you have a good steel under it.
You can coat carbon steel.
135 with a split point. 135 deg is less tool interface.
Split point takes less tool pressure.
Run a fine stone across the the cutting edge. Crates works best. Sandpaper is fine. So it’s smooth when you run your finger along it.
That very sharp edge breaks down quicker. And then you are dull.
The stoned edge is much tougher.
I’ll drill thru 4’ of parts of 410 or 316 SS without having to sharpen the drill. 2” drill. Regular HSS not cobalt.
I’m too lazy not to do it right. Some guys will go and hand sharpen 5-7 times for the same job.
Any other questions. Just ask.
And slowdown and keep the pressure up. This is the answer. I live stainless steel, working maintenance in the food industry.

wheelnut: Thanks. Yes, I’m very familiar w/ Graingers, but they tend to charge top dollar, so I usually look elsewhere unless it’s an obscure part. I don’t often drill stainless steel, but when I do, I definitely need the correct type of bit as my Chiner-crap bits won’t get the job done. I understand that different materials (hardened steels, etc.) require different type of bits, but I was thinking that a quality American made HSS set or Moly set would be adequate for my needs and cover most, if not all, the materials I work with.
nemotheangler: Thanks. I don’t think I need Cobalt bits at this time. Perhaps I’ll get a set to use exclusively on my drill press.

My Drill Sergeant said, “I didn’t see you at camouflage training this morning”
I said, “Thank you sir”
Do you know how they manufacture minuscule drill bits?
A little bit at a time.
Why isn't the drill ever invited to parties?
Because he's a boring tool.

What is it called when you leave your office building well before the fire drill begins?
Premature evacuation
I quit my job drilling ventilation holes in jet engines...
...it was just plane boring.
A blonde is drilling in the ice to fish when she hears a voice call out from above...
**There are no fish under the ice**
The gal looks up but doesn't see anyone. She asks - can I at least drill and see for myself?
The answer is in a louder tone.
**There are no fish under the ice**
The poor gal looks up and still can't see anyone. She thinks to herself - maybe I'm just hearing voices. She continues drilling.
The voice bellows louder than ever!
**There are no fish under the ice**
Now the blonde begins to tremble as she asks - who speaks to me?
**The owner of the skating rink**

ok. I'll allow that the blonde joke was somewhat humorous.

Norseman.
Viking
CTD.
I believe all the same manufacturer.
29pc for ~$100
I’ve snagged them cheaper on eBay.
Also sold as Fastenal brand. ![[Linked Image from i.ebayimg.com]](https://i.ebayimg.com/images/g/P4wAAOSw2PpfzlOZ/s-l1600.jpg) From Ebay I paid $28.78 for one 1/2" drill to test it. Norseman 175-VT Vortex Point Mechanic Length Drill Bits USA Made - 1/2" 2 months later I now realize I have no way to test a drill in a controlled experiment.

I ran into a piece of Inconel the other day. Had to break through it with carbide. Ordered a new piece to replace the bad one. No pecking around on that stuff.... I worked at a nuclear place once that was making heat exchangers out of inconel. Nastiest material I ever came across

My brother was a machinist. He had to work Inconel. It was for the toilet drain on a Boeing jet.
He said it was the worst.
