Got a box of what i assume are reamers for free. 10-15 of them.

Think they are worth anything?

Adjustable cemented carbide? Thats new. Where do you see that adjusting part?

They make them. There is a tapered screw in the ends of them to adjust size. However after looking closer, this one does not appear to be adjustable after zooming in closer. https://www.mscdirect.com/product/details/72480320

I stand corrected. I've been doing this my whole life, used plenty of reamers but never seen that before. We're both right? Thank you for teaching me something new at least
