Now, I like a high speed hand driver/drill....

  1. anyone else, but his is silly:


    A typo, I expect. Nonetheless, a two speed battery drill with 1,300 RPM high
    speed for 60 Bucks seems pretty decent. Those crappy Chinese drills that top
    out at 500RPM are far too slow.

    ** Not likely at all.

    That drill is SMALL and a small 24V DC motor can easily rotate at 50,000

    Notice that supplied bits include a 1.5 mm size - which operates best at
    speeds above 10,000 rpm.

    However, the figure for torque looks wrong cos 25Nm and 4550 rpm equates to
    over 12kW.

    Magnetic battery ???
  4. Hehe. One or the other perhaps. Most DC motors have a fairly linear
    torque curve between maximum torque at stall and zero torque at
    max RPM. The midpoint would be 3KW, 125 amps at 24 volts. Still
    seems too high by about 4x.

    Anyhow, who wants to sling that huge battery pack around? I wonder
    if it's still NiCD, and banned elsewhere so they're being dumped

    They say it is a magnetic battery.

    ** We heard you the first time .....

    Likely there is a magnet that holds the battery onto the drill.

    Or maybe you think " Steak Sauce" is made from steak ??

    It appears to have the same buttons as a normal drill to disengage the
    battery So I still wonder what they meant.There is some research into
    magnetic batteries but you would not be using one in a drill.

    Come on Phil, get real. You don't expect Wilson to have the intelligence to
    take those issues in, do you?
