The magnetic drill press includes a magnetic base coupled to a base housing for selective engagement with a ferromagnetic workpiece. A motor carriage is slidably coupled to the base housing, and an electric motor is supported by the motor carriage. A bit is received by the electric motor for rotation about a bit axis. An illumination system has at least one illuminator module coupled to a surface of the magnetic base. The at least one illuminator module is aligned to illuminate a work area of the workpiece.
In another embodiment the invention provides a magnetic drill press. The magnetic drill press includes a magnetic base coupled to a base housing for selective engagement with a ferromagnetic workpiece. A motor carriage is slidably coupled to the base housing, and an electric motor is supported by the motor carriage. A bit is received by the electric motor for rotation about a bit axis. A motor housing is coupled to the motor carriage. A laser is coupled to the motor housing for illumination of the workpiece along the bit axis. The laser is supported by the motor carriage for movement with the motor.
In yet another embodiment the invention provides a magnetic drill press. The magnetic drill press includes a magnetic base coupled to a base housing for selective engagement with a ferromagnetic workpiece. A motor carriage is slidably coupled to the base housing. An electric motor is supported by the motor carriage, and a bit is received by the electric motor for rotation about a bit axis. A motor housing is coupled to the motor carriage. A workpiece illumination system is coupled to at least one of the motor carriage, the base housing, and the magnetic base for illumination of the ferromagnetic workpiece along the bit axis.
Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
DETAILED DESCRIPTIONReferring to
The motor housing 14 and the motor 18 are coupled to a motor carriage 30. A rack 32 is coupled to the motor carriage 30. A pinion 34 is rotatably coupled to the base housing 12 about a pinion axis 36. The pinion 34 engages the rack 32 for vertical actuation of the motor carriage 30 along a carriage axis 38. The pinion 34 is actuated by a user via a handle assembly 40 (
Referring to
A laser 54 is disposed within the motor housing 14 for illumination along the bit axis 50. When used in combination with a hollow-centered bit, such as a hole saw, the laser 54 illuminates a workpiece along the bit axis 50. Thus, the laser 54 facilitates alignment of the bit axis 50 with a desired drilling axis. In some embodiments, the laser 54 may be electrically coupled to the power module 26, and selectively controlled by the motor control switch 28 or a separate switch. In other embodiments, the laser 54 may be powered by a separate power supply, such as a battery.

The dog hub 148 defines a torque transfer recess 156. The torque transfer recess 156 includes a pair of opposing convex walls 158, separated by a pair of opposing concave wall 160. The torque transfer recess 156 is configured to rotatably receive the torque transfer link 132. More specifically, the convex surfaces 160 of the torque transfer recess 156 allow for a small degree of relative rotation (e.g., less than ten degrees) between the outer spindle 140 and the torque transfer link 132.
