Infinity Tools DW735 carbide planer knives

[MikeMcCoy]

Infinity has their new carbide planer knives on sale for $199.90 (regularly $249.90). Seems pricey but I'm giving them a shot as I just installed my second set of HSS knives at $60 a pop in under 6 months.

Edit to add that this is a pre-order for delivery in September.

Ouch those knives cost as much as my planer. Let us know how well they work. Curious to see how much better they are than stock knives.

Here is a quick idea for sharpening planer blades.

I have an old Ryobi AP10 Planer that is still going strong. ( I wish it would die so I could buy a bigger better planer) But the cost of blades and blade sharpening was getting crazy. I have a lot of rough cut lumber to plane. So I built this simple jig for sharpening blades.

I started with two pieces of white oak 2" x 5" x 12". One piece is the base. Cut the other at the angle of the cutting surface of the planer blade ( base about 1 7/8") reverse the the piece and cut the other side. Attach the two sides to the base. Lay the two blades in and trim the center insert so it will nor quite touch the bottom when pulled tight. Drill a center hole for a carriage bolt and counter sink the bottom with enough clearance for the nut.

Then you can run a sharpening stone across the top or yu can turn it over and use the sandpaper on a plate to sharpen both blades.

Thanks, shoottx. Cool jig! What angles did you settle on for the blades to lay flush?

I see many have problems with the life of blades on this planer. Is there a reason other than cheap steel??? I bought a Delta 22-580 just before this DeWalt came out and I must have thrown around 500 bf of red oak, cherry, maple, and walnut through it with the original knives - haven't even had to flip them over.

$200 for knives seems high but the carbide should definitely wear better but I would be afraid of hitting something hard and destroying them. That sharpening jig seems to be the trick.

[MikeMcCoy]

I haven't had the knive problems reported by many and best guess, I ran a little over 400bf before turning the blades around. I was so impressed with the improvements I saw with the Byrd head on the jointer that it's more of a "I want to change to carbide" rather than a need to.

On the Ryobi AP10 blades appear to 45 degree. I have just sharpened 1 set of blades this way and the y came out very sharp. Havent run them on the planer yet but I am anxious to try them ion the next change. Will report on the cut after the change.

How did the knives turn out Mike? Worth the extra cost?

I'm also interested to hear your review on those carbide knives.

[MikeMcCoy]

A little water has gone under the bridge since this post was started. I can't give a review because Brian Holbren made me an offer on the Byrd planer head a day or two after I ordered the Infinity knives and they wound up getting sold as soon as they arrived.

[Tom Slick]

so how is the Byrd?

[MikeMcCoy]

That's a tough one to answer since my take is different than most reviews I've seen. I really like the decrease in noise level and the planer wasn't intended to give a "finish" ready surface so it does as advertised. The 735 doesn't have an excess of power to run the Byrd head by any means. Long term economics says the Byrd will be the winner because of cost but I would have liked to had a comparison of the Byrd with the Infinity knives but they had just come out when I had the chance for the Shelix cutter head.

For a while, Dewalt would give you a new set of knives if you complained about the life of their blades. With the help of a couple friends and a couple alias's I managed to rack up like 5 extra sets of blades from Dewalt.

WOW............I guess it doesn't surprise me that anyone who would pull a stunt like that would also admit to it on a public forum. Look up the definition of the word "fraud".

[agent511]

Never underestimate the ability of some people to commit fraud, then rationalize it also, for instance... "well they are a big company, they can afford it""they charge too much for their product so they deserve it", etc. It's a matter of ethics and personal morality, both lacking all too often.

In this case, the company went above and beyond by sending a free set of replacement blades to someone who asked. Unfortunately, that wasn't good enough.
