I got around 100 lbs or so of scrap carbide. Been sorting it for a while. I am hoping to sell some of it for $20 per lbs. The sold EM are not broken they just have usually a nick on the very top and would need a touch-up for good work. This is the left most pile. Above it are large EM that may be re-sharpened. Above that is the pile of better EMs most of which I keep. Above that is giant insert pile with two sorted piles of good and bad inserts. On the far right are broken carbide pieces. Yes I can ship it and I can trade it for something else machining.
Few observations:
1. As you can see the shop did not run things till they broke - a lot is OK.
2. The broken stuff is either large or small. Stuff between 1/4 and 1/2 seems to break rarely.
3. Almost all larger EMs are run harder than the smaller stuff - stuff above 1/2 shows a lot more wear than stuff under it.
4. A lot of inserts seem to never been used... some have been used half. Not sure why.
5. I may keep some longer carbide pieces - may use as a boring bar or something.
6. note sure what to do with say a 8cm long 3/8 carbide shaft from broken EM - I guess scrap?
7. for all the bad inserts sell it on ebay?
