DIA = Drill bit diameter RPM = Revolutions Per Minute SFPM = Surface Feet Per Minute But we usually know the values of everything but RPM so to solve the equation for RPM I find this formula more useful: RPM = SFPM * (3.8197186 / DIA.) 12 / PI = 3.8197186 The target surface speed for drilling mild steel is 50 - 80 SFPM Larger drill bits have a chisel point that does not really cut through ...

A Magnum Super Premium drill with its thin web will penetrate the work hardening stainless fast enough to continually cut beneath the chip which is hardening from deformation. This means the drill is cutting softer steel. The cobalt drill, with its thick web, cannot be fed at a fast enough rate to cut beneath the area which is hardening. As a result the cobalt drill is continually drilling int

How to choose the right drill speed. Quick Summary: Some approximate starting advice is to set the spindle speed between 700-1000 rpms for steel, above 2000 for aluminum, and slow down from there if you get discolored chips or heavy drill bit wear.In most cases the drill press will not be able to supply enough power or speed to follow the below recommendations.

So, to get the job done, all you need it a little bit of patience, and drill the material on shorter bursts, applying firm pressure. It will surprise you how little extra time it takes, and what you ...
