    Best way to cut wooden circles?

    I'd like to cut some wooden discs, and was wondering if someone could help me find the best tool for my application. The three options I've been looking at so far are:

    #1: Circle cutter bit for drill press . Several companies make these ranging in price from $10 to $100, and with a maximum outer diameter between 4 1/2" and 8 1/2". I've got an adequate drill press drill press with a good-sized motor, so this is a convenient option, but most of them seem to require a not-so-convenient pilot hole in the middle.

    #2: Router jig. This is pretty simple - just an aluminum sheet with a mounting point for a plunge router and a peg you mount in the center. I've already got the plunge router, so making one of these could be quite cheap; however, a pilot hole is still required unless you can find another way to keep the apparatus centered.

    #3: Dremel circle-cutting jig. Dremel makes a circle-cutting assembly that appears to be based around a suction cup - hence, no requirement for that pesky pilot hole. However, they don't work with cordless dremels, which means I'd have to buy another one.

    Any thoughts?

    The husband says that what you are taking about in #1 is a hole saw and
    with a drill press you don't need the pilot bit, remove that, make sure your work is well clamped down and cut your circle.... slower is better than faster

    Can you recommend a particular brand or model?

    Thanks!

    Does Lenox make one?

    Joseph, I do em on my band saw. I'll try to find the jig I use, I can cut circles from 2" to 48" on a 12" band saw.

    How big are the discs you want to cut? If they can have a center hole you could cut them with a router and trammel or on a table saw/band saw with a pivot point. If it can't have a center point you could make a template and use a router with a flush trim bit.

    I wouldn't use idea #3, I've never seen a suction cup that stuck to porous wood

    While I am very interested in your jig design, I don't have a bandsaw.

    As far as I know, the adjustable hole saws like that do need to be run with the center pilot. Even with the workpiece clamped to within an inch of it's life, the offset cutter will try to rip the wood out of the clamps and throw it around the shop, especially on a 5" hole.

    A regular holes saw like this in the drill press can get by without one:


    Most of the methods suggested so far involve a hole of some sort in the middle. Along the lines of Eric's suggestion, how about using a circle template and a plunge router with a guide bushing to follow the template? You could cut the template with the adjustable hole saw or any other tool that'll get the level of accuracy you need, then lay the template on top of your "money" wood and use the router to cut your disk. You'd use different templates depending on the type of router setup -- guide bushing or flush trip bit. Sort like this...

    Ok no one said there were any paramiters on this topic about cost or anything, but am i the only one that thinks the best way to do circles is with a lathe? No holes in the center and perectly round. any size you want and any thinckness. you can even round the edges over and make wheels. Do a whole cylinder and cut as many circles as you want.
