Huot drill bit question

[Jason280]

I came across a 29pc set of USA fractional 1/64 drill bits in a Huot box (up to 1/2"), and have a couple questions. Is Huot the actual manufacturer, or just the box manyfacturer? They are all marked with the fractional size, then "CO/USA". Any ideas the actual manufacturer, and what are the odds they are all cobalt?

What color are the bits? Got any pics? Cobalt are typically a light bronze color, but gold oxide is also close in color.

These are a light bronze color, almost a silver/bronze.

Huot makes the drill boxes. No drill bits.

 

[Jason280]

That was my understanding...but without any other specific markings, any way to determine who actually manufactured the drill bits?

Jason280,

Do they have the "backslash" between CO and USA or do they look like this...

I've worked in the industrial supply business for 42 years, and can say with some authority that those drill bits were likely made by Chicago Latrobe.

They didn't look like that....they were laser printed I believe, and somewhat difficult to see.

May want to ask a mod to move this to TOOLS, it will probably get more hits there.

 

[Jason280]

I didn't even realize it was in the wrong area....

Re: Drill bit question

Huot makes the index, they're a Minnesota manufacturer who supplies cases to TONS of drill makers. A picture might help.

Re: Drill bit question

CO stands for cobalt, should be a dull gold color from the heat treating process, sometimes they’re stamped with the content of cobalt like m-42 which means 8-10% cobalt.

Re: Drill bit question

These were marked on the case, bits are marked CO

Working on it.

I have them merged and deleted the second OP. Hopefully it was a copy/paste post.

I think that "Drill America" is a brand sold at big box stores, etc. I just read discussion of their products on a model engineering website, the general opinion was that they weren't anything special. I've never had any experience with them, though.

We’ve had good luck with in our shop and on-site, i buy a lot of bits and taps, so far no complaints with drill America’s. I don’t know if there’s difference but we get them through a commercial supplier and only get usa made.

"Came across" meaning they're used? If not, who is selling it?

Huot only makes storage/accessories and they're local to me.

Viking Drill and Tool/Norseman are also local to me and is a very large manufacturer of drill bits in the US and I know that they use Huot drill indexes.

Can you take a clear picture of the markings?
