Have been trying to find a place where I can buy both of:
1. 90 degrees spot drill AND
2. 82 degrees spot drill
or
1. Drill Tip countersink drill for 6M screws AND
2. Drill Tip countersink drill for 5/16" screws
This is for aluminum so HSS or Cobalt should work fine.
Thanks for any recommendation you may be able to offer!
