Double Eye Ring Drills

Paulus Violin Bow Double Eye Ring Drills.

Used in conjunction with the Paulus carbide spade bits for flat bottom eye boring.

These double eye ring boring bits are precision ground of high speed tool steel. The spade bits are set inside this eye drill and tightened in with the allen screw (included). As the flat bottom spade bit bores your eye hole this outside ring cutting tool bores the .5mm wall thickness ring. All of the spade bits have 6 mm shafts and all of our eye ring drills have the 6 mm bore to accept the spade bit.
