But it is a bit tough to hook and unhook to the drive unit. Dirt gets in between the output shaft and the female on the bit and you do not have the option to rotate the bit on the shaft to help work the grit out and get it on far enough to get the pin in.I have the round style where there is no hex to turn the bit, all the torque must be held by the 7/8" pin on each side of the bit. It takes alot to shear a 7/8 pin in 2 places at once. So unless you want some very large bits, and use it in tough conditions, I'd stay with the round. In these parts it is more common also. Maybe check with any local rental center to see what they use just incase you need to rent.Ken</blockquote>
