blue tooth

[bandmiller]

anyone who has ever ground chains (if he is honest) will sometimes blue tip, is it the kiss of death to a cutter. does the temper color soften the already kinda soft tooth (file hard) or does it harden it,making it hard to file. ?? not talking about really overheated teeth just a touch of blue.

It has been my experience, although limited, that too much heat hardens the tooth. Filing is practically useless at this point. Sometimes the tooth can be reground to take the temper back out.

Hi
I have seen Green teeth but never the blue color. It may have came from the dye in the toilet bowl, or possibly from eating Smurfs. Try getting a drink from another location and visit your dentist at least twice a year. LOL

Rich,Ive been grinding all my chains since 1976,and I belive your correct,cant detect any real harm,especially if their resharpened with a grinder.In fact if all cutters were made with harder steel they would stay sharp longer,but would require a grinder,like stihl teeth only more so. helmit and flack jacket on---frank

It depends on how hot you actually got the tooth. Seeing a blue colour onIy means you have exceeded a temperature of about 675 deg. F. It does not indicate how high the temperature actually got to. If you heated the tooth to approximately 900 deg. F. it will be at a softer temper than factory. If you heated it beyond the transition point of 1080 deg. F. the suseqent cooling by air and the quench effect of the mass of the tooth, will leave it at a harder temper than the factory. The hard portion is quite thin and usually a couple of CAREFUL grindings will take it off and you will be able to file it again. the same for a soft condition, but the softer zone will likely be a bit deeper.
