I have drill bits that have a 3/4″ shank. They are reduced shank bits for 1-3/4″ hole size. I have 1/2″ drills. I have looked for 3/4 drills with no luck. What am I missing here?
Probably meant for use in a milling machine with a collet rather than a drill chuck.
You can buy JT4 sized chucks in 3/4″ too.
