Drilling holes with small drill bits requires a certain amount of sensitivity that is hard to achieve when using a regular drill press. This attachment uses a small 5/32" Jacobs chuck that holds drills as small as #80. It is mounted to a shaft that pulls down out of the spindle and is returned by spring tension. On the shaft above the chuck is a knurled disk that is mounted in a ball bearing race so it can be used to lower the drill chuck. The shaft runs inside the bearing, so the disk doesn't turn as you pull it down. The whole assembly simply screws onto the spindle nose threads like an end mill holder, and the shaft and return mechanism go up inside the spindle. This drilling attachment allows you to drill small holes quickly and with the "feel" required to keep from breaking tiny bits.
