It’s official, I have joined the “screw up a part and reorder it” group. Which I’m sure most all of us are in. The dreaded TE wedge countersinking got me. I’m not sure what happened, as to why it chattered so much but it did and vans tech support said “replace.” I was using the Cleveland wedge drilling device, on a drill press running at 450 rpm. My fix for this is going to be….. drop the rpm to the lowest it will go (300) rpm, I have purchased the single flute countersink bit, and decrease the depth by about 2/ 1 thousandths. I have included a couple pictures of the mess and one I thought was interesting from vans tech support. If you have any pointers, etc, I’d love to hear.
