New "domino killer" dowel guide for drills

[Packard]

You won't be buying standard drill bits.
The outside bits are left hand twist.

The CMT bits, for their Boring Jig, are also right and left handed, and are solid carbide. Expensive though, ranging between $25.00 and $30.00 each.

You do have to search for them, but I’ve done it here, but when shopping note the shaft diameter and the overall length. It might not work with all fixtures.

It’s just a cruise around the Moon. Hopefully leaving around 6:30 pm Eastern time today.

Whoops...I got the right day but the wrong destination.

Those are the typical line boring machine type bits, steel shank, carbide tips. They have 10mm shanks, a depth adjusting set screw in the end, a flat face for the attachment screw. The black/orange paint indicates rotation direction.
These same bits also work in concealed hinge boring machines, which require 8mm holes.
The usual line bore holes are 5mm or 1/4", so all 3 sizes are available easily.

I use them (right hand only) in my CMT dowel template, which I use with a drill adapter. It can also be used with a plunge router and a 14mm bushing. The centering drill adapter is faster than the router, but both cut clean holes. I was under the impression that the entire bit was carbide; I might be wrong on that. But a very durable bit.

I also have an edge drilling template from CMT. They are not imported to the USA. I got mine from Amazon.de (German) but it shipped from Amazon.es (Spain), It all went on my regular Amazon account. Both jigs are very efficient for cabinet boxes. I especially like the spring loaded centering bit that guarantees perpendicularity.

Or make your own Domino killer by adding a fence to the CMT boring jig. The spacing is not adjustable and I believe it is 32mm on center. The bit diameter can be changed.
