Speaker 1: Hi'm Marshall Brain with today's question, what are carbide tips?
Speaker 1: When you buy a saw blade or a drill bit,
Speaker 1: it'll often say carbide tipped. Carbide or more specifically tungsten.
Speaker 1: Carbide is a very common material on any sort of
Speaker 1: cutting tool. For example, sab blades, lave bits, drill bits,
Speaker 1: router bits, and dental drilling tips are usually made out
Speaker 1: of carbide. Carbide is so popular in these sorts of
Speaker 1: tools because it stays sharper longer than most other materials. Additionally,
Speaker 1: some ballpoint pens use carbide balls because it helps the
Speaker 1: pen to last longer. With something like a carbide tip,
Speaker 1: sob blade, the main body of the blade is made
Speaker 1: of steel. The small tips of carbide are brazed onto
Speaker 1: that steel body. A good carbide tip might hold an
Speaker 1: edge ten to twenty times longer than a steel tip.
Speaker 1: Carbide tips do get dull. Eventually you sharpen them using
Speaker 1: the same techniques you would use to sharpen steel, but
Speaker 1: because they are so hard, you use a different abrasive.
Speaker 1: Something coated in diamond or a carbide abrasive wheel is common.
Speaker 1: If you've read how diamonds work, you know that diamond
Speaker 1: or pure crystalline carbon is the hardest material there is.
Speaker 1: Moistenite or silicon carbide is very close. Tungsten carbide and
Speaker 1: titanium carbide are both made of the metal combined with
Speaker 1: car urban, and they are also very hard. Tools aren't
Speaker 1: made entirely of carbide, partly because it would be very expensive,
Speaker 1: but also because the tool would be very brittle. Steel
Speaker 1: is actually a better material for the body of the
Speaker 1: tool because it's tougher and it's less likely to crack
Speaker 1: or shatter. And you do you have any ideas or
