I have been led to believe that it is very important to the performance of the job and the life of the bit to use the appropriate speeds, etc., when drilling various materials.
I was about to purchase an expensive drill-bit set -- which also advised a very simple (and I need simple) guide for drilling. Problem is that when I looked at reviews it is clear the bits I was going to buy are absolute crap. This makes me question the guide, although I'm hopeful I can still use it (i.e., put it in my "workshop" as a reference for when I do drilling).
Is the following table reasonable -
|Brick||Medium||Medium-low||Water or Air|
|Concrete||Medium||Medium-Low||Water or Air|
|Steel||Heavy||Medium||Air or Oil|
|Plastics||Med-Heavy||Medium-Low||Water or Air|
(Ignoring purchasing the most appropriate bit for the material), does the above guide only apply to all bits, or only the bit in question which is described as "Chrome Vanadium Shank, Titanium and Tungsten Tip".
Relatedly, there is a disclaimer that the bits I'm not going to buy are not designed to work with the drill's hammer function and should be used in regular mode even for masonry and concrete. Assuming I get a separate set of concrete bits, does the pressure, speed, and coolant apply to those bits as well?
