It's been years since I've drilled a hole with a Solberga drill but yesterday did so and impressed with the power feed mechanism. All you do is set the desired feed rate with a round dial, pull out the clutch knob at the end of the handwheel hub, lower the drill to the material..and drill. It automatically starts in power feed as soon as there is drill point pressure... and automatically releases the PF when thru the hole (or for blind holes... you pull up on handwheel or preset depth stop) Contrast this with what I previously thought was the ultimate "convenient" power feed... electromagnetic type with engage/disengage push buttons at the end of each hand spoke. The Solberga way seems even better... agree or disagree ?
