Century Drill Tool 11617 Letter Q Hss Drill Bit 3 Pack

Product Description

The CENTURY DRILL TOOL CO INC 11617 is a Letter Q size high speed steel drill bit designed for general-purpose drilling in wood, metal, and plastic. Each bit features a bright finish and a precision-ground 118-degree point, which provides accurate self-centering on flat and curved surfaces. Manufactured from premium-grade high speed steel, the 11617 maintains cutting edge integrity across a wide range of materials and repetitive use cycles. This package includes 3 bits, making it a practical choice for jobsite use where a backup is needed or when outfitting multiple tools at once.

The 11617 is suited for both stationary drill presses and portable handheld drills, giving technicians and tradespeople flexibility across shop and field applications. Letter Q sizing is commonly used when drilling pilot or clearance holes for specific fastener sizes, tapped threads, or precision fits. The bit is appropriate for use by electricians, HVAC installers, plumbers, carpenters, and general maintenance professionals who need a reliable general-purpose drill bit in a less common letter size.

Installation Notes

Install the bit securely in the chuck and confirm it is centered and fully tightened before operation. Always wear appropriate eye protection when drilling metal or plastic. Match drill speed to material type — lower RPM for metal, higher RPM for wood and plastic. Ensure the workpiece is properly clamped or secured before drilling to prevent movement.
