Extra Length Drill Bits are designed for general purpose drilling where extra reach is needed. Extra length drills can be very fragile and easily broken so it's usually best to drill as deep as possible with a jobber or shorter bit before switching to an extra length drill bit.
Plexi-Point HSS Drill Bits
Plexi-Point HSS Drill Bits
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.
