So I needed to install 5 of these Kreg tracks in my new RAS table, 5×6 screws each for a total of 30 screws. The screws need to be centered and flush (not sticking up half crooked) so you can slide the clamp bolts in the track. There’s little to no room for error. I was still contemplating how to at least center punch them when I was wandering the hardware store and spied these Isomax self centering hinge drill bits, brilliant!

Do they do exactly what they advertise, yep! It made this job fast and easy and every screw was dead center!

Self centering bits sure do come in handy!

I bought the three piece set by Snappy from Woodcraft, which are the same style and they work very well.

I wish I had looked on Amazon first though, as they have other brands for half of what I paid, and I think they’re all pretty much the same.

Self centering bits are great as long as they’re the good ones. I first tried General (just because I saw it first) and was not impressed. I now use VixBits ( ) and have had the same great luck you apparently found with Isomax.

P.S. That is one stout RAS, but please tell me you have a blade guard and don’t use it as pictured.

I got the three piece set in 1978 and they were called ViX bits then from a company called Liechtung. They are super for installing butt and piano hinges accurately.

John – the RAS is still undergoing restoration, the blade guard which is huge is sitting my shop sink awaiting cleaning and painting.

Jeff – yep that saw was manufactured in 1952, its a big mostly cast iron beast that takes 12”-14” blades.

Sounds like it was a good purchase, congrats

Ever notice how the blade looks bigger when the guard is off

-- Norman - I never never make a mistake, I just change the design.

Norman that’s a 12” blade, here’s one next to a 10” blade. They look even bigger and scarier in person.

Do not, I repeat do not, buy ANYTHING from General. They take some great ideas of tools and fixturing and find a way to F… it up manufacturing it, to sell for the cheapest cost and price.
They need to be extinct.
They are the duplicate of B&D, with Craftsman a close second.
