Scored some big Indestros cheap on eBay. Found myself in a bind needing bigger wrenches in my work truck and a combo/socket not fitting. Paid less than HF, and bought American.

Congratulations!!! Great job!
You got USA kept tools, majority of money went to a person who had them and did not leave the country!
A win-win for all of us

Stopped by the hardware store coming back from a call. I grabbed what was on my list.... I knew something was wrong as I picking them out of the rack. I missed one of the bits I need. KIMG0215.JPG
What do you use wire-gauge size drill bits for? (I didn't even know they existed until I saw this.)

I got this Central Tool 0-4" micrometer set in the mail today. I thought it was only a 3 piece 0-3" set when I bought it of ebay as that is what the seller had listed it as, but I pulled up on the leather tabs and viola, a 3-4" micrometer appeared. I only paid $65 and looks barely used, except for some damage on the top of the case. It also has all the gages and the shortest (and frankly, crappy) hex key I've ever seen.

No, not bolt/stud sizes. For inch sizes there are number, letter, and fractional drill bits. Yes, it's moronic, but this is how we roll with inches instead of metric.
So those numbers are _not_ the 0-14 sizes I saw on the tap chart? The ones where 0 is 0.060 inch and all others after that are 0.013 inch larger?

So what _name_ does one use to refer to them. Just number and letter drill bit size?

Yes, just a number or letter for the size rather than say. 1/8" or 3/32"

The numbered drills start around 0.040 for a #60 drill (61-80 exist but aren't common) and go up to 0.228 for a #1 drill. The letters start at 0.234 for a letter A drill and end at 0.413. It's a moronic way of classifying drills (and there are even a couple duplicated sizes between the number/letter/fractional drills) but it's how we get a sufficiently complete manifold of sizes with tighter spacing than the common 1/64" fractional steps. And yes, for example the tap drill size for a 10-32 tapped hole is a #21 drill. And the tap drill size for a 5/16-18 tapped hole is a letter F drill.

I would assume the letters were an attempt to standardize on thousandths, as that's how machinists measure their work? Just a wild guess, of course.

Capri Tools 3/8-Inch Drive Low Profile Ratchet, True 72-Tooth, 5-Degree Swing Arc​

Stock photo, (Is that allowed?) Sorry, hurting and too beat up to go down and take a picture ATM.
TBH haven't actually used it yet, but for $12.** I'm impressed. (Up to $15.50 now) Fit/Finish is nice, reverse lever nice, ratcheting action nice.

So if I ever have to tap a hole, I am going to study the tap / drill size chart _very_ carefully, then! Thanks for educating me. : )

One of my favorite ratchets. Have the same one. My go to when I need a 3/8 in that length. Thought about buying a second one for home use. Have mine at work. Going on three years of ownership and use it’s great. I think you will like it.

If you look at a chart for tapped holes, especially for #8 and up, fractional drills are close enough for home use; a .005" difference isn't going to matter (I hear the screaming machinists :D) . Obviously, this doesn't apply to a shop making parts for the military where everything must be checked.

What is nice about metric is that you subtract the pitch from the thread diameter, and this gives you the bit size. For M12X1.25 you get 10.75 and round this to a 10.8 bit.

At work we have a nice coolant exchanger so I wanted something for home I do alot of maintenance on the side. One guy had a 430 quote for a rear diff. Service if only I could do those all day on the side

Just got the box a few months ago still selling other toolboxes, almost all moved in, stereo finally wired up20230119_165029.jpgScreenshot_20230116_112557_Photos.jpg
I like the fact you picked your very expensive storage color based on your favorite drink.
