Big question is what drill bit size do I use to make this 100 into a 125 or there abouts? Nest size up drill bit says its a 12 and measures to 1.20mm , safe to assume this is drill bit to use to make this 100 jet into a 120? Next drill bit size is then a 13 and measurement is 1.25mm so would this be the Bingo bit to turn this 100 into a 125? Just want to make sure I'm reading into this correctly.
Tools available to measure bits
.95 or number 10 drill bit fits this 100 jet
measured and says .95mm
measured number 12 drill bit and shows to be 1.20mm
measured drill bit number 13 and shows to be 1.25
