portable circular saws blade rotation anti clockwise why ???

**matey** · 6th February 2005, 02:24 AM

hello all purchased a circular saw a while back and was going to use it today to cut up some old headbords, but noticed the blade rotates anti clockwise ,the teeth point upwards???

not sure why this is so ,i would have thought if the blade rotates a/clockwise it would have the effect of trying to lift the workpiece upwards and throw sawdust chips upwards, if clockwise rotation the chips etc go downwards,

could do with some enlightenment on why anti clockwise cutting action
thank you

As the blade rotates, it pulls the timber towards the base of the saw, holding it flat against the base. If it were rotating in the opposite direction, it would be pushing the timber away from the base, and you'd lose control. With a small piece of timber, the teeth would pick it up and throw it. With a larger piece, you'd have an awful lot of chatter, and the possibility of the saw kicking violently.

Also the saw would take off away/fowards from you, saw blades have excellent traction propertys!

I've been busting to tell you that the blade wouldn't cut, because the teeth would be facing the wrong way, but decided not to.

Not if you remove the blade and turn it over 180*!

It isn't counter-clockwise but rather the teeth come up from the bottom. Look at various saws, some have the blade on the left while others have it on the right hand side. Which ever side, it always pulls the wood down.

But of course if you look at the saw from the other side, it's rotating clockwise anyway!

You learn something new everyday.

I never thought about why the saw blade turns a specific way, I presumed the makers knew why.

I just learned how to use it safely and accurately.

Put the saw down, and step away! Please consider needlepoint... Just kidding!

Even that can be dangerous if you push the needle backwards.

Midge, just curious, do you flip your pancakes clockwise or anticlockwise?

esoteric pratts? never herd that one before...what is it?

Well, 'esoteric' means confined to a small group of people. For example, the discussion of detailed hand plane geometry would be called 'esoteric'.

And well, you're all being pratts because someone doesnt asks what you think to be a dumb question.
