DeWalt OEM N030675 replacement table saw riving knife DW745 DWE7480

I got this because it looked very close to the knife needed for a Porter Cable pcb220ts (which is discontinued and unavailable). It isn't the same, but all it took was a few minutes grinding. I took less than 1mm off, on just one side so it would slide into the holder (of course the curvature of the edge itself will be close to the same for any 10" saw).

I have never actually written a review on Amazon- but I figured I would save humanity frustration and multiple swear words. For those that have struggled with the fit of this riving blade- it took me quite some time to realize that you and to push the knob with the yellow areas IN after you loosen it- in order for the blade to slide in and out. I felt quite silly after dissembling the mechanism and messing around with the “set screws” to realize - I should have read the owner’s manual first. Hope this helps people with any issues with fitment.

This is not compatible with DW745 Type 1 saws (older models - mine is from 2007). I wish this was made clear in the product description but I also should take part of the responsibility for not better researching my saw. I did not know there were manufacturing differences in this same model saw based on the type number/year it was produced.

Installed on a kobalt jobsite saw. Perfect fit.

I trusted the previous reviews and got this riving knife for my DW745 portable table saw. It did not fit, this replacement was too large at the base to fit into the slot on the table saw. Good thing amazon has an easy return system.

This fit my Dewalt 745 type 20. No adjustment necessary. Loosened the bracket slid into place and tightened it down.

I have a DW745 Type 20 (which is the first listed as far as compatible). Know that mine did not fit right out of the packaging. It seemed like it wanted to fit and I thought the middle grove that runs up the middle was just not precisely manufactured so I spent time grinding that trying to get it to slide in to no avail. I finally removed the entire knife assembly from the saw and found two hidden set screws. When I loosened those, I was able to get the knife to slide right in place. I removed the knife, replaced the assembly, and flipped the saw back upright and now the knife installs and uninstalls just fine.

I purchased this to re-shape into a traditional riving knife when not using a blade guard. This makes the top edge of the riving knife always even with the top of the blade, enabling dado cuts to be made and at the same time preventing kick-back in normal cuts. I rough cut it by hand and shaped it with a disc sander. Happy I did it!
