PLEASE: these are NOT counterfeit inserts. These were purchased in a large lot from a local industrial auction at a huge manufacturing plant. I have been burned by counterfeit ebay inserts before, I know what it's like.
I have many boxes of different carbide inserts available, and will combine shipping wherever possible. If you are interested in multiple quantities, I will refund excess shipping charges OR if you prefer, I can make you a custom invoice.
