Review on Bosch 85078 Speed Carbide Tipped Keyhole by Muhamed Hogan
Great bit for making keyholes.
I use this attachment on my CNC machine to make keyholes in shadow boxes. I created a file that creates two perfect keyholes 16" from center as it is intended to be hung on rivets. This can also be done with a manual milling machine, eliminating the need for a CNC machine.
Pros
- New
Cons
- Drill Kit
