Question About Orifice Drill Bits
Hello. I've always used orifice drill bit sets. The one that come in the blue hard cases and are numbered not fractional. I am looking for a new set and notice they are pretty pricey. I was looking for a regular drill bit set online and came across a set that has fractional, lettered, and numbered drill bits. The numbered drill bits are 1-60 and I guess correspond to wire gauge.
What I want to know is if this is the same measuring system used to measure gas orifice sizes.
Training is a forever thing in a good technician’s life.
I sell knowledge in the form of hours.

Just buy the Anderson-Forrester set it's worth the price.
If I'm not mistaken they are one in the same. I'm sure someone will come along to correct me if I'm wrong.
