I remember about 10 or 15 years ago seeing an advertisement for a special drill bit that drilled a tapered hole that matched the angle of a pencil sharpened point. It was used to make small circular inlays by drilling the tapered hole, using a pencil sharpener to put a point on a dowel, glue the sharpened point into the hole and saw it off and sand flush. The resulting inlay could be made different sizes depending on the depth of the hole. I can't seem to find it anywhere now, does anyone know where I could find one of these?
