Abstract
A pilot pin assembly is slidably receivable within a tool bit of a drill press. The pilot pin assembly includes a first pin defining an interior cavity, and a second pin at least partially received within the interior cavity of the first pin. A spring is positioned within the interior cavity for biasing the second pin toward an extended position relative to the first pin.

A pilot pin assembly slidably receivable within a tool bit of a drill press, the pilot pin assembly comprising:
- a first pin defining an interior cavity;
- a second pin at least partially received within the interior cavity of the first pin;
- and
- a spring positioned within the interior cavity for biasing the second pin toward an extended position relative to the first pin.
A magnetic drill press operable to perform work on a workpiece with a tool bit, the magnetic drill press comprising:
- a base attachable to the workpiece;
- a housing supported by the base;
- a motor positioned within the housing;
- a spindle coupled to the motor for rotation about a rotational axis, the tool bit being attachable to the spindle for co-rotation therewith;
- and
- a pilot pin assembly at least partially extending through the tool bit for providing an indication where the rotational axis intersects the workpiece, the pilot pin assembly including a first pin and a second pin telescopically received within the first pin.
