dezz Posted January 31, 2012 Report Share Posted January 31, 2012 Hi, I purchased few secondhand tools recently and have an issue especially with jigsaw and DC727 drill. Tools have an annoying high-pitched whine when the trigger is first pulled under no load. The sound lessens as RPMs increase but the squeal of this drill is really obnoxious. Is it normal? I own DCD710 and it doesn't have that sound. Had many other tools and never had this problem. Link to comment Share on other sites More sharing options...
