Carbide Saw Blade

[DocHeb]

The best quality blades will have carbide bits that are hollow-ground so that only the leading edge of the carbide is hitting the wood on both the top and the sides. This decreases the heat buildup on the carbide tips. They can be re-sharpened, but it is difficult to do the job at home and get all the tips the same size and profile so they all follow each other in the kerf.

It was Pergo flooring and I don't know if it is aluminum oxide or not, but I expect it may be. The washing did wonders, but I'm still going to use the diamond dust hone as soon as I find one.

The flooring finish, by the way, is extremely durable.

To install the transitions from Pergo floor to tile, I had to drill a number of holes in my basement slab with a masonry bit . I bought 2 bits at Lowes which were name brand, for about $2.50 each. They each failed after about 6 holes.

I bought a mulit-pack of made in China bits at Harbor Freight which cost about $2.50 for 5 bits of assorted sizes, including the one size I needed. I drilled at least 12 holes with that one bit and it is still going.

Go figure!

I am quite sure Pergo uses aluminum oxide in their finish. Just think, your floor finish is almost as hard as diamonds. Tell the misses that, better yet, cut some small unique pieces from the scrap, make earrings and tell her they are almost as hard as diamonds, they are much harder than zirconium and I can custom make lots of designs for you. It just does not get any better! :thumbsup:

@DocHeb: Ah, the Piranha blades with their darn concave faces! If the faces are good, then you can get away with doing just the tops to sharpen them up; their tops are no harder to do than other blades. It just happens that I did one the other day, and I don't like them..... I actually know a saw filer who would re-grind a more conventional tooth pattern on any Piranha blades that came his way.

Yes, Pergo and other laminates do have that stuff in it. And it does a job on blades.

I have a 80 tooth Makita finish blade I would like to get sharpened. It was an expensive blade. One room with Pergo, and it could use a sharpening.

This thread makes me wonder, how hard could it be to sharpen these, compared to a chainsaw? Someone must make a file and jig.

I am quite sure Pergo uses aluminum oxide in their finish.
