Thats interesting Derrek.
I have only been able to get a good results with brad points on a fresh spoilboard or or if drilling in the same spot. If the the holes end up in a kerf of a previous part I get blow out. We run nested base so we have kerfs running every which way.
We run about 30 5X sheets of closet parts a day and surface only once in the morning.
As soon as I get a chance I will try just drilling a few thousandths though. I will have to try that on one bit 1st as I have a 10 bit row of 5mm on my block. I would need to calibrate each on to get that kind of accuracy on all. Could be worth it for faster cycle times.
But then again I think I am a bit picky about my holes. I tell my customers to build for their customers not themselves all the time. I have never had a complaint on holes. Maybe I need to heed my own advise :)
Brad points are so much faster through the top for me, I would love to use them.
My current subroutine is jog to top of material slowly bore through the melamine fast though the core the slow out the bottom. It really slows my cycle times.
Anyone else having success with brad points on through bore?
