As with most glittery and twinkling tool gizmos which catch my eye from time to time and I seriously considering purchasing this one.
Despite my interest I have some reservations on several aspects of the machine.
I am therefore hoping someone with intimate or a working knowledge of the machine can assist with a couple of queries please.
Firstly, the automatic speed change operations troubles me a little. Up until now most DP’s require a manual changing of the belts on the pulley gears to alter quill RPM’s This model however satisfies the operation by twiddling a buttton. This is all very nice and labour saving but does anyone know how the system operates? Is it some kind of expanding clutch? Is there access to the gear change pulleys or is it a sealed head unit. I have been asking myself, what is the cause for the escaltion in price compared to other DP’s. My fear is the RPM speed is controlled by some kind of circuit board and should it fail, which it invariably will do one day, does this then render the drill useless until a replacement control unit is installed, no doubt at great expense. Is the control unit the cause of the high price??
Also, has anyone an input on keyless chucks on a DP? I find them useful on a hand drill but how is it operated on such a large powerful drill without wrenching your wrist out of socket.
Any info on this machine and it’s value for money will be highly valued.
