One of the only times I used the Dremmel on my bikes was to grind the spokes that were protruding from the spoke ends on the rim before putting down the rim tape. The rear wheels that I have laced have this situation due to me using the same length spokes for both the drive side and non drive side. I used a ball shaped cutter that was in the kit. It worked great without any damage to the rim or spoke end. Just a steady hand and that comes from 45+ years of tool grinding! Joe
