2.0 out of 5 stars Think of it as two slightly overpriced bi-metal hole saws., April 1, 2005

By	veganMalcontent - See all my reviews

This kit is really two bi-metal hole saws, an arbor, and some extra trash to throw out. I bought it to bore out the undersized holes on two metal-clad french doors. I hoped the flimsy plastic guide that comes with this kit would steady the hole saw. The first time I pulled the trigger on the drill, it was like that scene in the New York episode of the Simpsons where Homer uses a jackhammer to remove the boot on his car with comical results. To finish that door I ended up butting some clamps up against the guide to prevent it from moving. For the next door, I'll simply cut a hole in a piece of plywood and clamp the plywood to the door, which will make a much sturdier guide.

For a set of two bi-metal hole saws with an arbor, you can get better quality (DeWalt) for less money. Do yourself a favor and go buy DeWalt hole saws in the same sizes and make a jig similar to the one just described.

4.0 out of 5 stars Great for wood doors, April 26, 2006

By	Jess Wright "home repair junky" (Phoenix, MD) - See all my reviews

I bought this jig and used it successfully with wood interior doors. It was simple I set the two plastic pieces for the right setback and tightened it onto the door. Drilled the holes and had a great result. I replaced 20 doors with no issues.

I tried using it for a metal door and the bit walked around on the metal. I ended up using the template that came with the lockset. I used a centerpunch and hand drilled it.

4.0 out of 5 stars Decent tool if you know what you are doing , May 31, 2008

By	H. Wu - See all my reviews (REAL NAME)

I got this tool from one of the local home improvement store. Amazon's current price is better. In any case, it's cheaper than buying two separate bi-metal hole saws and a mandrel if you are working on only one brand of locks. Used it to install 3 deadbolts on metal doors. Worked just fine. Yes, the plastic guide is just marketing gimmick. Don't use it. Instead, drill a small pilot hole with a drill bit first BEFORE using this tool. Take your time to get it done accurately. And use a strong corded drill with a 1/2'' chuck and a 2nd handle.

Note that when changing the hole saw from the 2-1/8'' to the 1'' one, just remove the inner part of the mandrel, and leave the outer part on the 2-1/8'' saw. The previous reviewer apparently got confused by the instruction.
