I used a 20mm forstner bit to give me a well 10mm deep. I need to drill a 10mm wide hole through the timber (45mm thick).
I used a 3mm wood bit so it would centre perfectly. On a test piece, using the 6mm wood bit next meant the hole was off centre. So on the main work, I used a 6mm hss bit which worked. But when I used 8mm and then 10mm, the edge of the hole became splintered.
How do I avoid this?
What was the correct technique for what I wanted to achieve?
Should i have drilled the hole first and used a forstner bit second?
