IRWINTools IRWIN Drill Bit, 3-Cutter, Self Feed, 2-9/16-Inch (3046013)

Q: Using a hand drill, I am boring holes into driftwood without going all the way through...is this the best tool for that purpose?

first use a thin pilot bit with a piece of tap wrapping as a depth gauge, and then use a foerstner bit if you want a clean, flat bottomed hole. If you are just dowelling, then I would use a steel bit (A bit for drilling through steel) don't use a ship auger if you don't want to go thru the other side since they self feed quickly and will probably pull thru.hope this helps.

Q: Has anyone used this for drilling into hardwood stumps?

I drilled out a stump last summer and it was not easy. I tried using a 1/2" drill and almost broke my wrist. My neighbor then brought over a 3/4" drill with a bar on it and I was able to finish the job. I had to brace the bar against my leg when I drilled. I was able to get down 10-12" while still being able to brace the bar against my leg. Be prepared to put in some time.

Q: On a wood lathe making cups.... do I need to slowly work my way up to this 2 1/2 bit, or can I use only this bit? I use all kinds of wood too.

There should not be a need as far as the bit itself to work up to it. Beyond that, you may want to check with the manufacturer of the machine that you are doing the wood lathe on.

Q: Would this be a good choice for drilling through a used railroad tie?

Railroad ties are saturated with creosote and that might clog up this bit, a good quality paddle bit might be a better choice.
