I have been told that the Berea El grande nibs come with a 10mm x 1.0 thread. Can anyone verify this and what is a good source for a tap this size?
Unless they have changed it in the past couple of years, m10-1.0 is correct. I have used several but haven't bought any lately.
Victornet.com has the taps for $6.10. However they have a $25 minimum order. You can pick them up on Amazon for about the same price with shipping in the 4-5 dollar range.
Also MSC, Mcmaster, etc, but these sources are generally more expensive
