A used DC-380 I bought came without a wrench to loosen/tighten the jib nuts (knife securing screws). The 5/16 that I use on a jointer is too small. 10mm is a tad too large and will strip the bolts. I don’t have a 9mm. Is that what I need? If you know the correct wrench dimensions, please let me know. (I don’t have calipers to measure, or I would.) Thanks,—Kevin

Kickback may be correct, but I remember them being 10MM….one or the other should fit. Problem is you will liikely have to grind a regular wrench down (thickness) some to use, at least I think I did. Get a HF or other cheapie, it will be good enough.

Well, ok, I figured it out. The size of the DC-380 planer jib nuts / knife screws requires a 3/8” wrench. The one that I had was indeed too thick to fit between blade/jib and head. A belt sander upside down in a vice did the trick. Thanks to those who responded. —Kevin
