blades for planer

[Mike Stanton]

:D i went to an Industrial carbide tooling yesterday and asked them to price making carbite blades for my dewalt 735 planer.They are going to call the first of the week with prices. Mike

[Bruce Page]

Mike, they ain't going to be cheap! :eek: :eek:

Keep us informed

[Dan Smith]

Mike,

Any news on price yet?

Thanks,

I called the carbite people today. 300 a set for carbitefor my dewalt 735. So much for that idea. They are checking on price for steel 1/8 that can be sharpened. Mike

[Bruce Page]

Yup, I knew they'd be a bit rich. Carbide as a material alone is expensive. Machining is done with diamond tooling. Add the two together and you have high dollar.

I'm surprised that he could do it for only $300.

Mike, keep in mind that the DW735 was designed for non-sharpenable knives and the indexing system makes it nearly impossible to adjust them should you go that route. (Same goes for the Delta 22-560/565/580 and I believe, DW734) The disposables, since they are double sided, are not much more expensive, if at all, than knives that can be sharpened, especially since it's not something you can do yourself all that easily without special equipment. You cannot have any variation on the edge across the entire width--they need to be "exact".

MIke, I've owned the 12 1/2" Delta and now the 13" DeWalt both of which use replaceable, double edged blades. They're just too cheap to worry about. You get two passes with each set. I think the 13" will last even longer since it has three blades instead of the two on the Delta. BTW, when I flip them over, I mark them with black felt tipped pen so I don't have to wonder later, "Have I already flipped them over?" :confused:

Carbide does not give as good of a cut....its brittle....HSS is better in a planer.

[Chris Padilla]

My understanding: Carbide's sharpeness will last longer than HSS's sharpness BUT, one cannot get Carbide as sharp as HSS. Carbide also is more brittle than HSS as Mark pointed out.

So a long chunk of carbide in a planer probably won't do well. Now if that carbide is put on a spiral cutterhead (or a Shelix like Byrd designs) in the form of squares, it will probably work very, very well.
