The difficult drilling of aerospace parts are addressed in the design of these heavy duty drills. These drills are made to NAS Type B specifications for drilling hard steel, stainless, titanium and other difficult materials.

These special purpose Plexi-Point Drills are designed to cut plexiglass, polycarbonate, and other acrylic plastics. The cutting angles are reduced to keep the drill from biting into the plexiglass too fast. This point produces a clean hole and prevents the drill from breaking the plexiglass when drilling through the backside.
