More specifically called a Radial Arm Drill
Or the more technical term, Overkill.
When you have time, figure out the kWHr per hole. Kinda like the gallons/mile computations for ocean liners.
I prefer the term adequate
Lets assume it takes 30 seconds to drill the average hole, and that we use the machine to 25% of its available power.
The motor is rated at 600V 15A
25% of 9kw is 2.25kw
30 seconds is approximately 0.00833 of an hour.
2.25kw * 0.00833 = 0.0187425 kWHr per hole or ~18.75 watt hours per hole.
by that math 3 holes uses the same amount of power as it takes to run an 60w lightbulb for a hour.
You should change that 60w bulb to a FIRST e-watt LED.
