Thread: Wearing router bit

what type of timber?

It wasn't a pre-primed laminate? The primer that's used on that stuff here in Oz is very abrasive and will wear thru router bits like nobodies business.

Fir. Ordinary 2x4s

would not have thought Fir would be too hard on cutters, is it carbide or HSS if HSS may have become over heated

was the bit 1-3/4in long or 1-3/4 in diameter?

what glue did you use for the glue-up?

How fast were you feeding? Going too slowly will generate a lot of excess heat and cause the edge to wear much faster

WOCO tungsten carbide : What is the difference between tungsten carbide and solid carbide?

This link may provide some insight to your issues dependent on whether the bit you were using was Carbide or Tungsten Carbide.

I don't know who wrote that article but it's utter bunk. There is no such thing as "carbide", it just means that it's a compound of carbon and another element - like silicon carbide, or titanium carbide.

When anyone in industry says "solid carbide" they mean that the whole tool is a solid piece of tungsten carbide, rather than tungsten carbide tips that are brazed on to a steel body. Provided that the grade of tungsten carbide is the same, there is ZERO difference between solid or tipped.

I am not going to worry about that article that I put up there ,it was merely a means of getting the OP to consider the options besides those that have been offered ,we are here to offer up options to any issues.

Sorry, but I really think you should worry about the article because it is blatant mis-information.

With all respect, I don't think that offering options that have no basis in reality and that are, therefore, totally meaningless is productive.

This is a Freud router bit. I think we can fairly safely assume it is made of high quality materials. Although carbide does come in different grades the only binder, not to be confused with a coating, that is likely to be used in the tooling that woodworkers use is cobalt. Without the binder the carbide isn't able to be formed/machined in to a solid article. Yes, I agree with Elan, whoever wrote that article is a complete idiot.

It was not my intention to mislead as its spurious in effect ,I will therefore apologise to the OP for that posting.
