PIREP: quality drill bits matter!!!
Hi Guys,
I'd often buy my drill bits from Avery or Brown, but I had had to make a Aircraft Spruce order, so I'll pick up some drill bit stock too.
Fast forward to a few weekend ago. Working on drilling the firewall to start the mounting of FF components and I had a heck of a time drilling the firewall, especially when it was backed up by a structural component. I'm using my best SS techniques; lube, low speed, consistent pressure, sharp drills. What am I missing? The drill bits were poor quality.
I picked up a dozen #40 135 deg split points from Pan American tool (I think Avery used to stock their stuff) ... and, somehow, the impenetrable SS turned into butter. wow!
I don't know whose product ACS is stocking, but for SS, quality sure does count.
