great tool, clean cuts precise edges even on plywood saves time between holes by not having to remove plugs as you would in conventional hole saws

Very Sharp resulting in a clean precise cut.

I used this bit to bore deep holes into pressure treated timbers. It worked very well. The cutting action is aggressive but still left a relatively clean hole. I used both a power drill and a hand brace to bore the holes. When using a power drill I found that removing the centering drive screw from the bit reduced the aggressiveness a bit and made the cutting action finer/smoother. When using a hand brace, I found that putting the drive screw back into the bit improved the cutting action. Thus, having the option to have the centering drive screw either in place or removed was a beneficial feature.

I used this bit to drill through 4x4 post so I could slide a line post (1-5/8" dia) through as a handrail for some outdoor steps. After reading a couple of reviews recommending using a corded drill, I decided to try a cordless anyway. I went through 3 lithium batteries after only 2 holes. This bit is very aggressive. I concur with others, use a powerful corded drill with 1/2 Chuck. The shaft on bit is 7/16 " so it will not fit a 3/8 " Chuck. Once I switched to a corded drill , life got much easier. Left a very smooth hole and a clean break through. I highly recommend this bit.

It's great now, but out of the box it was so dull it wouldn't bore into white pine. had to spend an hour with a small diamond stone to sharpen the cutting edges to an edge good enough for it to self feed.

I purchased this bit to bore through 5" pressure treated landscape timbers. I used a 1/2" drive electric drill with a side stabilizing handle. This bit cleanly chews through this pine material without any problems. Given the high rosin content, I occasionally had to withdraw and tap the bit to clear the chips that had adhered to the auger tip.

This bit is a great time saver if you have a drill that is powerful enough. I used a Milwaukee right angle power drill with 1/2" chuck to drill thru two stacked 2x10s. I even hit a nail, it went right thru it without damage to the bit. Because of the great torque requirement it may be un-save to us this bit while standing on a ladder. Not suitable for battery operated hand drills.

It is not clear in the listing, but the screw feed portion unscrews from the main bit. Good for replacing. When purchased, I received a spare feed. Unfortunately, on one occasion when reversing, the feeder unscrewed from the bit and remained in the wood. It took a modest effort with needle-nosed pliers to remove it.

I had to drill 16 holes through 4"x4" posts, this made the job easy, the self feeding tip worked great and the bit had no issue chewing through the posts. It got jammed up once in a while, but you just pull it out, clean out the wood that is jammed and keep on drilling. Great bit for the price!

Worked good for drilling through a cedar 6x6. Got clogged a bit, but may have been the wood type. Short shank required a bit extender.
