Question regarding drill bit sizes? Hi, Everyone
I’m looking to purchase several diamond coated hole saw bits, for a complete set
I’ve noticed a lot of differences in actual size regarding the size of bits in mm.
I’m mostly concerned with the schedule 40 bulkheads, but in sizes of ½”, ¾,”1”, 1.5” & maybe a 2”. Is there an exact size regarding bulkheads in mm? or do different manufactures have different sized schedule 40 bulkheads? If so what would anyone recommend for sizes?
Any help would be appreciated
Thank you
