Query: Do it all Drywall hangers best bit

Portercable is the only manufactuer of the size 3/16" drywall router bit.It fits all drywall cut-out tools(rotozip,portecable,dewalt).It cuts out doors and windows faster than backcutting & using a hand saw.It also cuts out vents and boxes.It does the job faster than any 1/8" bit on the market.The 1/4" window/door bits are not usable with boxes & vents, where this 3/16" bit is.The bit has a very long and durable lifetime.The best router bit on the market.Only the real drywall profesionals are even aware of it's existence.Be one of the 1st.
