Re: Drilling Philosophy 101
I, We do not have to drill because our system in not as good as DELTA. I drill with a .35 just to speed thing along for myself.... I do not need to drill, and the jobs I did today I did one with and without drilling and customer could not tell the differance as did I. It may just be habit as long as I am cleaning out the break with the drill as one other said I just give it a pilet hole.
To stop a crack, I use the same .035 to stop the crack, (no need to go any bigger than that... More of an eye sore if not filled properly). I do not pop the end like others do. I will flex the crack from out side and inside to stop it and have no problems with that...
I think drilling should be done with the smallest bit possable if you are drilling, and that is why I use .035 and inline cracks with .025 unless and if I forget to switch them out then the .025 is my impact driller also.
To satisfy my self, I sized up my bits and they are on the Machinist mic. they are at .025 and .032.. and I drill .050 deep or less based on the depth looking at the bit.
Again, it is not that our non DELTA system can not inject with out drilling but it is by choice..
