M4 Rivet Nut Tool Tip, Replacement Mandrel

So with lots of time staying at home because of the virus, finally got to use my rivet nut tool with the M4 insert.First try, the threaded pin snapped off, was using the stainless steel insert on 1/8 aluminum stock as a test trial. What????? Very little pressure was applied. This is nothing but cheap steel and not worth anything!!!! I am so disappointed and obviously mad. Shame on you for selling such inferior products.

I agree with the other review, broke the first use yet I bought another praying it was only a bad hair day. No bargain here. I wish it was robust to use twice.

Striped the M4 mandrel threads on the first use. Don’t bother buying this for use with stainless steel inserts, the tool is too soft and it’s a waste of money.

This Rivet Nut Tool Tip is the exact kind that came with my Zision tool. I wanted extras in my kit for that one time I go to far and break one.

I wish my rivet set came with this size. Must needed!!!

well made, good value

Put 4 rivet nuts in and the thread snapped off in the 4th nut. Do not buy, this is junk
