Small depth drill I tried longer depth drills until I saw Richard Raffan use a short one. Here is mine with a standard size 1/4" drill bit with a few notches to note depth. I use this for shallow bowls but mostly for doing boxes. Probably for 90% of my depth drill tasks. No ferrule since I don't put any lateral pressure on it. After your post with the yellow scoop from HD I went out and got one. Great idea Odie and thanks for sharing. I posted it in my chapter's newsletter.
