Quill feed for a portable drill adapted to be mounted to a work surface |
摘要 |
A magnetic based drill assembly comprising a support platform mounted to the magnetic base for attachment to a work piece includes a feed mechanism operatively connected to the platform for rectilinear movement between a fully retracted position and a fully extended position. The feed mechanism includes a splined collar slidably mounted to the splined arbor for movement relative to the splined arbor and for rotatably supporting a drive tool. The motor is mounted in a stationary position offset and substantially parallel to the feed mechanism to reduce overall height and weight of the drill assembly. As the splined arbor is located within a cylindrical feed arbor a liquid coolant can be directly injected on the drill tool and workpiece during operation of the drill assembly. Further, an electrical feed rate monitor provides a signal to the user to indicate the optimal feed rate of the drill tool.
