Circular Saw Mystery

I just got a new circular saw -- my first "worm drive." I noticed that the blade spins in the opposite direction (CW) compared to the direct drive/sidewinder (CCW) variety I've owned in the past. What's the reasoning behind that? Any pros or cons to which way the blade spins when making a cut?

It always has to turn so the blade is pushing against the direction of feed. Otherwise it would be climb cutting and instantly go out of control. Once you get used to a worm drive you'll never want to go back.

The blade should spin in the direction the saw is fed.... unless the previous owner has it on reversed. The teeth will enter underneath the work and spin upwards pressing the work against the bottom of the saw's base, no matter which type of saw you are using, a sidewinder or a worm drive! :smile3:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Congrats on the worm drive!
I've got three, and will never go back to a sidewinder, or blade - right saw (minus the track saw) ever again.

If you compare, the worm drive saw the blade is on the opposite side of the motor as your circular saw. Maybe the worm drive is for the southpaw.

You need to make sure you have the blade fitted the correct way round for the type of saw, otherwise the teeth will hit the wood backwards and thats big trouble.

maintenance on worm drive saws is higher. They need regular oil changes in order to last the distance.

Hypoid drive seems to be the best of both worlds, no maintenance but has the power of the worm drive.

CW or CCW depends upon WHICH SIDE you are watching the blade from. Seen from the same side (either left or right) both worm drive and sidewinder saws have the SAME direction of rotation. Blade always pushes under the front part of the saw base while cutting in either case.

Keep thy axe sharp.
