Feed and speed equation

[Ger21]

Is the bit getting discolored? If not, then your feedrate is probably fine. A general rule with wood, is to cut as fast as you can, while still getting an acceptable quality cut. That will achieve that maximum tool life.

Hi Longy,
The router that burnt out was a Black and Decker KW780 600watt the bottom bearing seized and over heated the router it was just working to hard trying to cope with the bearing seizing. It was my fault it had been cutting continuously for just over one hour, what I should have done is to let it cool down after 20 minutes. So my fault.

Don't blame yourself mate, over the years B&D have cut quality to cut the selling price, in other words made down to a price not up to a quality. Having said that I have a B&D router still going strong after 40 years and it's only 500W they don't make em like they use too LOL
