[CAUT] pinblock material, drilling speed, feed rate ?

[Dr. Henry Nicolaides]

I'll try slowing down to aproximate that speed and drill a few test holes...perhaps 1250 rpm was too fast.  It's been awhile since I drilled delignit.  I think the last one I drilled I made two passes...first with a smaller bit and half way into the block and then with the  normal bit.   BTW, do you use a brad point or sprial bit?

Thanks for your feedback.
Henry
