How oftern should I change Drill Bit?

[mdskora]

Just wondering how oftern I should change my drill bit?.... Some clients have said my drill is "hotter" than usual.. normally they don;t feel it at all.... but a couple have said they can feel the heat... not burning just warmer than usual... does this happen when i need a new bit?..
Also are women more sensitive when it is "period" time?... both were due...

Thanks Mel

if its a metal bit, it will lose its sharpness over time. obviously so many circumstances will contribute, how many clients, how much product you take off, which product you use and the quality and type and courseness of the bit itself.

if its getting a bit on the dull side it might be that you are needing to use more pressure on it to make it cut so it could be producing more heat because of that.

the longest lasting drill bits are those called 'swiss carbide'
