The guide is made of plastic and does not really provide a true wiggle-free alignment. Particularly on a 1 3/8 thick door there is probably enough free play to get into trouble if you are not careful aligning the drill.On the plus side, the hole saws provided are of quite good quality. Note that this guide will only work properly on doors that are 1 3/8 or 1 3/4" thick. Use in odd size doors will result in a mis-centered latch/side bore. The guide does adjust to appropriately locate the cross bore for backsets of either 2 3/8 or 2 3/4 inches. Conclusion: probably of sufficient durability for a homeowner doing a small number of installations; not going to cut it for a contractor.16 of 17 people found the following review helpful.Good Quality Homeowner Jig, But with Mandrel LimitationBy A HomeownerIn general, I agree with the previous reviewer. Our home has older (50+ year old) doors, and I have used this to replace worn-out doorknobs (entire mechanism). As there was an existing face-bore (in the no longer standard, smaller size of 1 1/2"), some jig was needed to correctly drill the current 2 1/8" standard face bore ... you can't stabilize a hole saw without one if the mandrel is in the air.That said, I also agree about not getting a perfectly centered latch hole in our doors that are a little under 1 3/4" thick. But, it's certainly more than good enough. The error of perhaps 1/16th inch can be corrected in positioning the strike in the door jamb. The limitation is in the mandrel: the larger threaded adapter for the 2 1/8" saw is ROUND! It is not hex, so you cannot remove it with a wrench (like you can with a normal mandrel), and ended up using another (better grade) mandrel for the 1" latch bore hole saw. I eventually got the adapter off ... when it was all but welded to the 2 1/8" hole saw, from which I doubt I will ever get it separated.Other than that, I could not have been able to replace the older hardware (as described above), and so give this a slightly better rating. (Purchase was at a local hardware store, at a slightly better price).The competing Irwin product looks interesting as the router template has the potential to save a lot of time in chiseling the inset for the latch in the door edge.10 of 12 people found the following review helpful.Satisfaction with a smile.By Robert A. MeenaI own another unit that was more costly than this door installation kit; however, it is designed for wooden doors and not bi-metal.I own plenty of DeWalt tools that I am very happy with, and it was a natural for this selection.This less-expensive tool allows me to use either unit as required.See all 20 customer reviews...
