Hi all
Just wondering what size of diamond bit I would need for a 1.5" Bulkhead. With a measuring tape it is pretty close to 2.25 inches but I would like to be exact. Unfortunatly I dont have a measuring caliper at home
Also If I drilled this hole a little bigger than 2.25" or 57.15mm for you metric folks would a 60mm 2.36" hole work?
Thanks
