Blade question for 22114 Owners/anyone?

[ragswl4]

Anyone know the hook angle on the blade that comes with the 22114 saw? The black one, 40 T, part #OR91720. Failing that, how does one accurately measure hook angle on a blade? Thanks!

It should be easy enough to measure, you'll need a protractor like you had in grade school.

Lay the blade on a piece of letter paper. Trace one tooth tip and the arbor hole in relative position.

Draw a line thru the blade tip and the center of the arbor hole.
Draw another line tangent to the inside edge of the tooth tip; extend the line and use the protractor to measure the included angle.
as shown that's a positive hook. - Consider that leaning in the direction of the cut.
Zero hook would have the tooth edge tangent line pointing back thru the center hole,
Negative hook would appear to be leaning backwards.
I would bet a lot of money that a table saw blade coming with a table saw would have a positive hook. probably around 15 degrees. Negative hook blades are sort of special purpose and a small percentage of all saw blades.

I'm almost certain that it's a positive hook, but I've never done more than glance at that blade.

Loring's method should work well and seems simple enough. If you've got another blade with a known hook angle you could compare to get an estimate. Most 40T blades have a hook of 15-20 degrees.

Here's a pic of the Leitz blade that came with my 22124...might be different than what's on the 22114. Looks to be ~15-20 degrees...


In comparison, here's a Ridge Carbide TS2000 with what I believe is a 20 degree hook:

Thanks, how did I know Loring would have the answer.

BTW, this is a nice blade. I am not sure if it is Leitz blade like the 22124, but I believe it is. I got this saw for my Dad last Christmas and helped him assemble it. I think I remember the blade being Leitz. At any rate, we chopped up some thick white oak on it and it performed very nicely. Its a good blade for a factory blade.

Yes, it is a nice blade considering its the OEM blade. Using Loring's method I measured a known angle on a Freud blade (20 degree) just to make sure I would do it correctly and worked great. The Craftsman (Leitz?) blade measured 0 degrees. I thought that odd for a table saw blade but maybe some Combo blades are that way. In any case that's great for me as I needed to replace the blade on the RAS I just bought and this works out perfect. Would rather have -5 degree but this blade was just taking space in a drawer.

Made a crosscut in the RAS with the blade on and it didn't try to climb and very little self feed so I think this is a good blade for this purpose. I will not RIP with the RAS in any situation.

Thanks for the help.

The blade I have is defintely different. Has Craftsman on the blade and an OR91720 part number and is black in color. I also laid it down on top of a Freud blade with a 20 degree hook and they are totally different. In comparison the Craftsman blade looks like a negative hook on top of the Frued. Don't know why Craftsman would supply a neutral hook blade with a table saw but in this case it works great for me in the RAS. Saves buying another blade. The one that came with the RAS had .040 runout. Stopped the saw cold when I tried to cut with it. YIKES!! Thought I had smoked the motor.
