Reliable, Accurate, Strong
By Daniel A. Koblosh
Dozens of doors--it never fails. Handles all common backsets and diameters.
Do order the smaller-diameter spade bits for the edge bore. The standard 1" is a bit large for some lock fronts. 15/16" and 7/8" are available from boringjigs.com, Classic Engineering's website. Also available: carbide bits for cross boring.
The bits are actually driven by the drill via a quick disconnect adapter. You chuck up the adapter and then hook up to the bits, both of which have to mounted into the jig before you mount the jig onto the door. Get the adapter with the 1/2" shaft. The 3/8" shaft can do the job but there is a lot of torque cutting a 2-1/8" lock bore and the 3/8" adapter shaft can bend. The 1/2" adapter shaft is very stout.
This device works from the edge and one side. You don't have to bore from both sides of the door. Also, bore the edge bore to full depth first. That way there is less material for the 2-1/8" bit to remove and it goes faster.
I like to use my 1/2" Milwaukee Hole-Hawg drill. The two speeds and excellent power really go. High speed for the edge bore, low for the cross bore.

By Bryan
I don't do a ton of doors so I have been getting by with hole saws and such. Hole saws take a lot of time and they can be difficult to perfectly line up from one side of the door to the other. I finally bought this kit and man what a difference! I have used it for about 16 doors so far and it is one sweet tool. Each door has come out perfect. I used to fear doors, now I actually look forward to doing them with this tool and my Porter Cable plane. I will buy the carbide bits when the steel bits start getting dull.

By Richard Cozzens
Today I used the Classic Engineering Boring Kit for the 1st time. The set up was incredablely easy and very accurate. The holes were smooth, and very precise. The only thing I am not happy about is the unavailability of the bits for this kit. Maybe I have just not located the correct place to purchase spare bits. They are not available @ The Home Depot and I could not find them in Tool Crib. Overall this tool is very well built and does it's job well
