Dado blade tooth count
Greetings all. This is my first post to the group, and my first post to a
newsgroup! I am upgrading from a wobble dado to a set. I plan to use it for a variety of projects, hardwood, softwood, plywood and MDF. I am leaning towards a higher side blade tooth count, in the 20+ range on an 8" set. Does this sound reasonable? I am leaning toward the Freud SD308. Thanks for any input. |

That sounds like a regular tooth count for an 8" dado. "higher" counts would be in the 40-tooth range. Chris |

I think most are about 20T. Check out www.infinitytools.com for the Dadonator and www.ridgecarbide.com for theirs, as well as the Forrest. All are good performers. The Freud is good, but one of these may offer something else for you. |

Can you actually tell me who makes a 8" dado blade set with the outer blades having 40 teeth? Seems it would be almost impossible to keep the chippers teeth from coming in contact with the outer blades teeth. |

I know of at least three--the third is actually 46 teeth. http://freud-tools.com/freudsd8safd1.html http://www.1blades.com/products.ecs/list/164/1584/0/5/ http://www.dimarcanada.com/products/...groupIDVar=250 Chris |

Dado blade tooth count
From the 15 Blade Test in FWW (comments are my summary - read the full
article for your own interpretation): Amana 65804 - 46T - This is their Melamine blade but tests showed it worked great overall BC Saw & Tool 3008400 - 40T - Not a top performer Everlast DS840 - 40T - Not a top performer Systimatic 37160 - 42T - Not a top performer By "Not a top performer" I mean there was at least one negative performance aspect in the tests. Oddly enough, all the best blades, except for the Amana, were all 24T. Negative hook seemed to work best. |

The out side blades need to make smooth cuts on the edge of the dado whether it be with or across the grain, solid or plywood. The more teeth the smoother that cut is. A good dado blade does not require further clean up with a router. |

If you have a sharpening service around you can get your dado blade resharpened, If they know what they're doing, they'll make sure that all the blades and chippers cut to the same depth. The local guy hates doing dados because of this, but he does do them. Chris |

If the edges are rough and or splintered the joint looks like crap. Not totally like cross cutting oak with a rip blade with few teeth. Basically you normally see much much more of the edge of a dado than the end of a dado. |

With fewer teeth and cutting cross grain the intersection where the piece fits into the dado will be more likely to have a rough or splintered edge at the dado. |
