A simple, low cost, and versatile option is to hollow out a truncated conical void in the rotating spindle, coaxial with the axis of rotation. Tools or accessories can then have a mating male conical shaped shank, which precisely fits into the void. The pressure of the spindle against the workpiece serves to drive the tapered shank tightly into the tapered receptable. The friction across the entire surface area of the interface provides a surprisingly large amount of torque transmission; so that splines or keys are not required. This system is known as a machine taper.
