Whether you opt to use a Dremel or a Drill, it is imperative to use quality bits. Below are links to HSS Steel & Titanium Bits for use in completing the pins with 1st Time Quality Results.
Dremel 628 Precision (Standard)
Dremel 631 Brad Point (Standard)
I DO NOT RECOMMEND using the Dremel 636 Brad Point (Metric) - Use the U.S. Standard 631 Kit.
I speak more about this Starting at 35:20 in this Live Stream & Then at 51:30 I speak about the bits that come with a P80.
