Good worthwhile video.........There's a lot to know about drills and drilling and he just scratched the surface... Thanks for posting..

Here's a series of three excellent videos from mrpete222 on drill bits..The third in the series deals with sharpening them.

Good video.......but.

He mentioned slow drilling. For wood, this may not work well with some bits like the twist bit. Usually higher speeds and slower feeds.

In metal- If you run a higher rpm, you must feed the bit faster to prevent overheating. Smaller bits- higher speed, large bits- slower speed.

Speaking of drilling into metal, I found a great video on youtube which I will try to post later when I get home. Anyway, I had to drill holes in a support bar for a barn door. I started drilling with a power drill and a bit and I got nowhere fast. I watched the video, switched to a battery powered drill and reduced my drill speed and watched for the metal pieces that the guy describes in the video and it worked great. I did start with t smaller bit before I moved on to the 3/8" bit.
