Review: Worked like a champ - I had to relocate a drain line in our laundry room, and figured it was going to be a bear of a job, considering the size of the hole… but with this bit, it turned out to be prettY easy… that spiral screw on the bit pulled the darn thing thru the 2x4 with ease… no effort on my part other than guiding the drill…. MADE AN IMPOSSIBLE JOB EASY
Review: This is a quality tool - I was trying to make a hole with the grain in a 5 inch diameter piece of Osage Orange wood. I might as well been trying it in a billet of steel! Osage cuts easily with a chain saw and splits well, just don't try to drill a very big hole in it. This tool worked quite well for a ways then it dulled enough I had to quit using it, but no other tool would do the job either. This tool would have been fine in any "normal" wood. ej

## Questions & Answers

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

### ⭐⭐⭐⭐ Really heavy duty drill bit!
*by T***. on July 16, 2021*

To help out with my long-delayed garage interior build-out, I bought this bit so I could drill holes through 2x4 and 2x6 wall studs and framing for routing the 2" PVC drain pipes needed for some sink installations. This bit is made really well and works great, but the standard electric (corded) 1/2" drills didn't have enough torque to keep the bit cutting due to the rate at which the aggressively spiraled flutes on the outside of the self-feed tip pulled the bit into the wood. It was also about as much as my old wrists could stand, too! :-( Since each bit comes with an extra feed tip, I resolved the problem by using a grinder to remove the tops of the spiraled flutes so that the tip would still center the bit in the hole being drilled but allow me to control the feed rate based on the amount of downward pressure being placed on the drill. This bit is precision cast and ground, and cuts a very clean hole even when the board is well-seasoned and tough. Further, the casting is robust enough so I believe that it could be re-sharpened at least once if needed. Despite the "star" I deducted due to the excessively high self-feed rate issue I needed to resolve, I'd definitely buy this bit again. However, unless I could use it with a drill press, I'd simultaneously plan on buying a heavy-duty 3/4" hand-held electric drill due the amount of torque it calls for and resultant stress it puts on a drill and the person using it!
