The CENTURY DRILL TOOL CO INC 11606 is a Letter F high speed steel drill bit designed for general purpose drilling across a range of common materials. Manufactured from premium grade high speed steel with a bright finish, this bit features a precision ground 118-degree point that promotes accurate entry and clean hole starts. The 118-degree geometry suits most general drilling applications in wood, metal, and plastic. This package contains 3 bits, making it a practical choice for shops and field technicians who keep spares on hand. It is compatible with both stationary drill presses and portable handheld drilling tools.
This Letter F drill bit is suited for trade professionals and skilled tradespeople performing layout, fabrication, or field drilling tasks that require a fractional-equivalent letter-size hole. Letter F corresponds to a 0.257-inch diameter, commonly used when drilling pilot holes or clearance holes for specific fastener and tap sizes. The bit works in metalworking, woodworking, and general plastic fabrication contexts. The 3-piece pack provides backup bits for continuous production or job-site use where bit wear or breakage is a practical concern.
Designed for use in standard drill chucks on stationary drill presses and portable drilling tools that accept Letter F shank drill bits.
Letter F drill bits are installed and replaced by machinists, fabricators, HVAC technicians, electricians, and plumbers performing layout or clearance drilling. Ensure the drill is powered off and unplugged before changing bits. Secure the bit firmly in the chuck to prevent slipping during operation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain point geometry.
