Will the 1 in. bit bore a hole that will fit 3/4 in. PVC pipe easily?
Asked by newpuppymom August 8, 20184
Answers3/4" PVC is just over an inch in outer diameter, you would need a 1-1/16" forstner bit

I was really impressed with how clean of a cut this forstner bit provided, but it has to be used on a high-speed drill. This bit is about as sharp as a knife and is meant for cutting very clean holes/depressions in a finished piece, such holes a spade bit cannot reliably do. My first project with the bit was cutting depressions to fit dowels for a children's play ladder. The bit drilled quickly but allowed for good depth control. It cleaned saw dust and cuttings out very well. The center spur is a great feature for accurate holes as well. Ideally, you want to use this bit on a drill press but I was able to level it well on my hand drill. I used my DeWalt XR at it's fastest mode (2,000 RPM) and the holes were near flawless. I experimented at a slower speed on scrap wood and the hole splintered. This bit fits a 3/8" chuck and is made in Austria, so you know it is quality. The bit also needs to remain sharp so store it well.

I used the bit to mortise hinges on new wood shutters I installed, a technique I learned about on www.thisoldhouse.com The bit was steady, and cut neatly and cleanly, making the job much quicker.

amazing quality , highly recommend for a recess fasteners , carriage or other type of bolts,
the reason for 4 stars, is at the base i wish the company made it square so it grabs better on the drill chuck, i had to keep tighten the the chuck, other than this it is awesome, be careful with the pressure you apply as it really goes in very easily, truly great product
