Sometimes, however, the "dullness" is a result of pitch accumulation that can be solved by cleaning.
I don't think I'd use stripper, but a little naptha or lacquer thinner on a shop towel or rag might do the trick.Iseem to remember soem commercial products to due just that. Is there anything we may have already in the shop that can clean them? Alcohol, paint thinner, stripper? I have a few that just might respond to taht treatment.....
The usual signs of a dull bit are poor cuts and/or burning of the cut. The bit may also overheat and darken. Bits will become dull from use, but will do so more quickly with misuse - like trying to remove all of the material in a single pass when working with hardwoods.I know this might sound silly, but im very new to routing so far ive used my router just for testing havent actually built anything YET! still trying to get my shop finished but bought a router on sale , but now ive heard you guys talk about how dangerous it is to use a dull bit, Will I know when my bit is dull? is there any tell tale signs that i should be aware of and looking for once i do start using my router on a more regular basis?
thanks in advance for your responses.
