The Modelcraft Collection includes Drills, Reamers & Pin Vices. Successful drilling depends not only on using the right drill bit for the job, but also in using the right techniques to guarantee accuracy. It could well be that a small Archimedean drill will allow you more control than mounting the bit into an oversize power drill. Taper reamers are ideal for finishing and deburring panel holes.
