1/8 Inch Riving Knife for DeWALT 10″ Table Saw
Tooljam
| Posted in Power Tools and Machinery on
To the good folks on this forum: My DeWalt 10″ table saw comes stock with a thin kerf saw blade. I am considering going to a standard 1/8 kerf blade, however I cannot find a 1/8 inch riving knife to replace the 3/32 stock riving knife. Surely I am not the only one wishing to do this. Any suggestions would be greatly appreciated.
Thank you in advance…

ok
I wonder if you need to replace the riving knife. Maybe you can use it as is. Does DeWalt offer any guidance on this matter?
EDIT:
I found the online manual for the DeWalt DWE7491 and attached the relevant part below.
It says the riving knife should be thicker than the blade's plate but thinner than the blade's kerf. Using this data, you should be able to determine if your current riving knife is safe to use with a full kerf blade.

The knife will line up with the arbor side of any blade you put on the saw so if you cut with your fence on that side you are protected. On the other side in theory you have a bit less than perfect fit but in practical terms stock should not be able to ride up the back of the blade to kick back.
Thank you all for your responses. MikeInOhio makes a good point that manual aligns with my thinking, however this is me first table saw and I am very inexperienced. I would imagine that the body of a 1/8 inch kerf blade would indeed be thicker than the stock narrow kerf blade. MJ also makes a good point, but it seems like the knife would line up with the motor side of the blade, with the wider kerf extending beyond the arbor side of the knife, thus providing the opportunity for kickback.
Anyway, it seems like someone should be selling thicker riving knives to accommodate thicker blades. I have done a fairly thorough search and come up empty handed. Thank you all again for your helpful and thought provoking responses.
Personally, I would never use a 1/8 blade on that saw. It just works better with the thin kerf. I had a 1.75 hp contractor saw for many years, and when I tries switching to a 1/8 blade, performance dropped off noticeably.it just wasn't worth it.
They likely don't make other riving knives for that saw because it's really meant to be used with thin kerf blades. Just my 2 cents.
Your point is well taken. My main interest in a 1/8 inch kerf is for making spline groves for picture frames. I suppose There is not much chance of kickback if I use a crosscut sled set up for corner splines, so I could have a dedicated blade for that and use a thin kerf for everything else. Thank you for you response.
That's what I would do. Or use a flat-bottomed thin kerf blade for the splines. The strength is in the glue surface area, and that is the same no matter what the thickness.
Good point. Thank you...
If that is a direct drive saw the arbor is mounted on the motor and the motor is on the arbor side of the blade, as opposed to the arbor NUT side of the blade.
