Using a quill or handwheel feed to advance drills smaller than 1/16" in diameter can lead to broken drills, because the leverage provided by those methods makes it difficult to "feel" how the drill is cutting. If you don't need the micrometer depth control of a handwheel feed, the sensitive drilling attachment will make your small hole drilling tasks easier. The attachment consists of a 5/32" Jacobs drill chuck that slides on a central shaft. The shaft attaches to the spindle with a holder that threads onto the 3/4-16 spindel thread in seconds much like an end mill holder. A spring contained inside the brass spacer tube helps support the chuck and return it to the "up" position. The chuck will hold drill bits from 5/32" to as small as #80 (.0135"). The attachment is easy to install in a few seconds. Just insert the spring tube up into the spindle and thread the attachment body onto the spindle thread. To use, grasp the red, knurled ring which rides on a ball bearing on the main shaft. Pull the drill downward against the spring tension and let it return when done. If you drill a lot of small holes, this attachment will come in handy. It may even pay for itself in the long run in savings due to less breakage of expensive small drills.
