/// Drills except for air powered drills are geared down for torque. This low RPM will defeat what you are trying to achieve. I do however have a suggestion. Use a welding grinder and a wire wheel for most of the work. Mine runs at 30K rpm. I use a twisted cable wire cup. As the grinder winds up the wire is spun out and the cup flattens out. There are flat wire wheels also available. These wire wheels throw wires so watch out.

A tool can be made from a stretcher nut (also called union, or joint) since it will chuck in a three jaw drill. Use the largest your drill will accept. The threaded hole is centered so that a threaded bolt can be a shaft if jammed by a regular nut at the drill end. Additional nuts, jam nuts and an assortment of washers put any abrasive material you wish on the other end. The length of the bolt will position the drill relative to the work end. There are abrasive tools such as this already available but they are expensive and never fit the application. A stack of one inch wide heavy sandpaper, fanned for balance, with the working ends tapered rather than square has worked for me.

There is a needle chipper available from Harbor Freight if they are sill in business.
