2.8K. If I use a larger or a smaller bit or drill some other
material with it I open the belt lid, and look at the speed table
list for materials and bit size. My bench top drill press only ever
this reminds me to spray a clear coat over the speed table on mine
I did so already for the motor wiring diagram
gets used for my tapping head, so it gets left at its slowest speed
as well.
I think I'm going to lower mine below 1,000 and see how I like it
Most of my odd drilling is done on one of the CNC mills, and every
single operation is calculated for a solid conservative speed and
feed based on material, bit size, horsepower, bit strength etc.
Do you ever use boring bars for wood? this might solve a problem
I have with drilling deep holes in wood
Well, except stainless which I try to drill as aggressively as
practical so that it doesn't work harden on me halfway through the
hole.
do you mean the stainless gets hard when you start to work it?
I didn't know that
