<p>The Sear Craftsman 315.10491 is a reversible 3/8" corded drill that was first sold in 1990. These drills were originally manufactured for Sears by Ryobi and some parts could be available through authorized Ryobi Service Dealers and the SearsPartsDirect website. The 315.10491 printed owners manual (Sears part# 612547-180) and some parts are apparently available from SearsPartsDirect. However, the 612547-180 PDF owners manual is not currently available for download from the Sears ManageMyLife website. Ryobi online websites do not list any drill parts manufactured for Sears. A Sears model comparable to the single-speed 315.10491 in size, case and specifications seems to be the 315.10496, but parts interchange has not been verified. The next model up in that series of Sears drills may be the 315.10411 which is variable speed and the owners manual is available for download as 1006753L.pdf at the Sears ManageMyLife website. <p>
