CTD Drill Bit, 21/64" Type AQF

CTD Drill Bit, 21/64" Type AQF

The CTD 092180 21/64" Type AQF Drill Bit is a premium high-speed steel (HSS) jobber drill bit engineered for precision, durability, and consistent performance in demanding drilling applications. Manufactured using high-quality tool steel and built to strict industry standards, this bit delivers reliable results when drilling through metal, wood, and plastic. Its gold and black oxide finish helps reduce friction and heat buildup while improving corrosion resistance, and the 135° split point tip minimizes walking for cleaner, more accurate starts. Designed for professionals and serious DIY users alike, it’s the kind of drill bit that keeps holes straight and projects moving forward—because nothing slows a job down like a drill bit that refuses to cooperate.
