Got time for dumb question?

[trackman]

I see some say they use #3/0 blade is that the same as a #3 blade?  If so why the /0 just asking.

[Scrolling Steve]

Not the same...a 3/0 is much smaller..takes or can be used with a # 70 drill bit and the  #3 blade uses a # 60 bit ........Those are the bit sizes recommend by Flying Dutchman blades.

Not a dumb question at all.  The #3/0 is much thinner than a #3 and the #3/0 has more teeth per inch.


The #3/0 has 38 teeth per inch and the diameter is 0.024.
The #3 has 27 teeth per inch and the diameter is 0.035.

Yea, I'd like to know also...  the width of .024 w/ 38 teeth or   

                                                                 .035 w/27 TPI

Does not explain the designation 3/0  or 3

    but meantime

The 3/0 vs the 3 is a size designation. I see folks have posted some of the measurements. It has to do with the thickness of the blade, for example 3/0 is .008 inches thick making a very thin blade that can do extremely tight turns and very delicate work. Normally blades this thick are easy to break and for thin wood. A #3 is .014 thick. Still cuts a very small kerf, is stronger and can be used on thicker wood. I use them up to 1/2" thickness but they will get dull faster then a larger blade. Also the thinner the blade the slower my feed rate goes. Hope this helps explain this.

The 3/0 designates three 0's. Not all blades come in all sizes but it might go like this...000, 00, 0, 1, 2, 3, 4, 5, and so on.
