Last crawled date: 10 months ago

Cardinal M840 Base - Use to stamp M8 X 40 Stainless steel or copper washers with seed words, pin numbers, wallet name, passwords, serial numbers or whatever you like. Based off of the original BlockMit die. Made to use 6mm punches. The slot for the punch in the die insert is 6mm and requires 6mm square punches. Sometimes these punches are referred to as 3mm punches because of the text size, but the punch should be 6mm square punch.

Depending on your machine and what material you use, you may need to scale up about 2% or more. The important thing to know is that the slot for the lunch needs to be as tight as possible so as to prevent jumping of the punch but loose enough for the punch to fit.
