Spyder 2-1/8-in Bi-metal Arbored Adjustable Door lock kit Set 5 -Piece

Great once you figure it out

I really liked the blade once I figured it out. You have to take out the bolts and flip the sides in different directions to adjust the sizes. It would have been five stars if it had better instructions.

This version works better and it easier to adjust

Worth the bit more to get this version you line up the pilot hole first instead of the plastic shroud. Worked great, just remember to stop and clear the waste out when you're cutting the holes!

You can use this if you’ve never done it before.

Amazing. Easy to use. Simple for someone who isn’t savvy with tools

Works well. Pull to detach and swap bits.

Works well. Figuring out placement took a while, but it’s a quality set. The quick eject feature using the button, and sliding the mechanism up and down the bit was cool to learn on youtube. To switch the attachment to the larger bit, you need to pull the base of the attachment downwards while screwing it out of the smaller bit. Good luck and happy DIY-ing!

Slab Away

Simple to use and creates a solid solution to a new slab you are installing.

Everything you need in one package, except drill.

Takes all the guess work out. Easy to follow instructions and is setup to do both patterns. Comes with everything needed to use it too.

Makes it simple.

Easy to use and align on the door, sharp holesaws make clean cuts.

Not cheap plastic, holesaws included

Drills straight holes, plastic is firm not to move around and cause holes go get off center

Pull the flared part of the arbor to unscrew saw!

It worked as described. I was able to easily add the hole for a deadbolt and the quick change arbor makes it easy to switch out the hole saw. Having not used Spyder’s arbor before, I would have liked it to include instructions for changing the saw, but finding that online was easy enough.

Tool can get a little in the way of the hole saw

Lineup tool somewhat got in the way of the holesaw bit but was able to make it work.
