4-Inch HSS Jointer Knives for Sears Craftsman 351.21724 351.217240

If you need an everyday construction site set of blades, look no further than these. I cut approximately 30 brace blocks from 2x4s for a deck. One blade did 60 cuts like the first cut. I even did a one vertical cut on a 2x8 at the end. All were done on pressure treated lumber, I’m impressed. Can’t beat the price and I will be ordering more. 6/12 tpi for those who want to know.

These work like any other blade that I have purchased. I have not necessarily found any great difference between the most expensive brands and the lower priced brands since I tend to challenge the blade with all types of materials. I would lump this in the mix and buy these based upon the price. At a dollar and a half, for each blade, these are on the very affordable side of what is available. I have sometimes used long metal blades for demolition if I have a large amount of metal embedded (could be conduit, etc.).

I don't often review but I have gone through many planer blade sets for this planer. I'm very glad there is an exact fit replacement as it seems Dewalt has stopped selling blade replacements. These seem to be an exact fit. All dimensions are exact except they are consistently .02 grams heavier and there's no pyramid stamp. I only did the weight because I could not find discrepancies (LxWxHxT). I read a review that they are not as good as the original, don't last as long. May be slightly softer material, IDK...TBD. I will get back to you on this.For now I am giving it 5 stars. I'm on my 9th double pack of blades from Dewalt. That's 4 blade sets per double pack. 36 blade changes. Excellent planer. Glad FoxBC picked up this replacement part.Price = matchesFit = matchesLife & cut = TBDHope this helps, Cheers!

FOXBC 9 Inch 6/12 TPI Demolition Reciprocating Saw Blades for Nail-Embedded Wood, Bi-Metal, 25-Pack with Case --- Received 25 blades as advertised. Haven’t had occasion to use one yet but they are thinner metal, but solid and sharp. Demolition blades are usually bulkier than these. Fit easily into my Dewalt battery operated reciprocating. saw. Plastic case is adequate for keeping them together but doesn’t look like it would take much abuse.

Partial review only, as I need to put these through their paces. The blades are well formed and have no obvious flaws. No curves, errors, etc. The case could use a bit more strength, though, as both pieces of mine are cracked.

I have an old craftsman jointer that desperately needed blades. I bought these and am super happy. Swapped the old ones out and the jointer is back to life. Blades were dharp and flat which is all that's necessary. I'll buy this brand again when I need another set!

Will get dull a little faster then their heated counterparts. However for the first time in 5 sets of blade I’ve just rotated these and did not see a single chip in the blades. This usually happens with any other blades I’ve tried including original DW735 13” blades.
Im going to use these from now on only, needs to be rotated just a little more often, but at the price point they are great. If you start questioning their performance then rotate/replace and go again with a fresh cut. 5 stars!

These last almost as long as the expensive ones, they stay strait just as well, and cut very well. Even though the blade will dull slightly faster (i didn't really notice this until i measured the cuts and compared, it's not much), the amount of cut per dollar is higher than the expensive blades, and the amount of efficient cutting per dollar is higher too, since you are working with a fresher blade more of the time.To put it in perspective, the guys that were doing the demo work did not reach 6 inches further to get the expensive blades, they just grabbed these (they were both sitting on the supplies table). These guys hate changing blades and such, because they see it as wasted time, so for these to choose these much more economical blades tells me that I'll be buying these more often.One note, they come with an expandable blade case, but the plastic is "so-so", you probably won't be keeping the case and putting more blades in it like you would some similar cases that you buy separately, but at this price, the case is, essentially, a freebie with the blades, so it's much appreciated.

Quality. Good weight

there are more expensive, higher quality blades available, but this is still a great crosscutting blade and very much worth the money.

I got this for planning old rough Purple Heart after I destroyed the factory knifes ..I’ve excluded before and after photos with no sanding straight out of the planner

Nice container. Worth restoring with a bit of duct tape.I like to test these kinds of saw blades in a hand-powered handle and in a basic battery-powered saw. This gives me a pretty good idea of how well they perform without too easily overheating, which is murder on cutting edges.I'm not sure it shows very well in these pictures, but the kerf produced by hand cutting is wider than that produced with a power saw. I would have liked to see a bit wider kerf, which would have allowed the coating of these blades to last a bit longer than it does.The steel I cut was a medium hard framing steel, as was the deck screw, which is much harder than typical wood fasteners.I'd choose a bimetal blade with 8-tpi for wood demolition unless a lot of deck screws are involved. These blades are best suited for metal, as described.I was able to make a low angle plunge cut in wood and soft metal. For harder metals intended it be cut with this blade, a plunge cut can be started with a Dremel tool pretty easily.Recommended on price and general utility.

Works great

I make a lot of end grain cutting boards. Those things are really tough to level out after final glue up. I had been using a drum sander, but the heat generated and other factors just made it nearly impossible to get the boards flat. Now, I can use the planer. I make VERY light passes, but this thing cuts end grain!! And it puts a reasonable surface on the board so I am not having to sand out the horrible grooves from the drum sander. I start at 120 grit now. Saves me HOURS of work. Could not be more stoked on this cutter head.

Didn't think about Taking a picture, I just put it on and started using it. They fit perfectly and I will order more when I need them. They also arrived faster then expected.
