Off to the side here a bit...

Had a supplier come in the other day. He complained about the order being small, so I said, "yeah, you're right." and then tossed it in the trash.

You should have seen the guy dive in after it. Think his name was Ed or something.

I plead innocence! I've never been to Washington so it must have been an imposter.

just a bit off topic if its steel i can have as mutch as i can have all off cuts mostle 4x2 1x2 2x2  and so on don't do mutch in aluminume or brass

I guess these two high performance taps would qualify as "dumpster diving" results because they were given to me by my employer before being tossed. They were used in a tapping seminar for task specific taps in given materials.

Both are M8x1.25 6HX taps. The high spiral is one for blind holes in austenitic (300 series) stainless steels. The other is for "short chipping" carbon steels such as pre treated AISI 4140, 1045 and similar. Barely showing any signs of wear after doing about 64 holes each.




Note how the "short chipping" one is like a combination spiral point & spiral flute. Because the materials it's meant for do make short chips, the spiral point shape helps break chips while the 15º helix carries them out of the blind holes. The "Inox" tap curls up the stainless steel chips tight and the high spiral pushes them out of the hole. These would be over $50 each if I had to buy them, glad I didn't have to! I don't know if I'll ever need an M8 tap, though ready when I do!

Embrace the metric system Ken!  M8x1.25 is one of the most commonly used taps in my set.  Along with M6x1 and M10x1.25.


By the way 

Today's haul. Actually, all of this stuff is from the same dive. I can only carry so much when I leave work so I bring it home in batches.

I use a lot of M10x1.5 and rarely use M10x1.25

That's some pretty good diving there Ed.

Darren, I know you're kidding because you know that other than having to change gears on my lathe to single point cut metric threads, I have no gripe with ISO/metric anything. I routinely alter my lathe's DRO and my mill's control between metric and inch systems.

And I do think Jack is right about the 10x1.5 threads. That's the "normal" standard (coarse) for 10mm. I have that, plus I have a 10x1.25 and a 10.1.0 tap.

Not much to show today but my hands were full and it was snowing out so I just grabbed this gear stock. It's steel so it weighs a bit despite its size.
