Titan Usa CD66609 Extra Length Drill Bit 17/64 Hss

Product Description

The TITAN USA CD66609 is a high-speed steel extra length drill bit designed for drilling deep holes that standard-length bits cannot reach. At 8 inches overall length with a 5.5-inch flute length, it provides extended reach in confined spaces or through thick workpieces. The bright finish is left uncoated for general-purpose use. The 118-degree standard point angle allows easy starting on flat surfaces. The straight shank fits standard drill chucks without adapters. HVAC technicians, electricians, and plumbers routinely use extra-long bits like this when drilling through framing, structural members, or equipment enclosures during installation work.

This bit is suited for drilling through steel, iron, aluminum, wood, and similar materials in residential and light commercial applications. Typical uses include running conduit, pipe, or refrigerant lines through framing or sheet metal enclosures, or drilling access holes in equipment cabinets. Its 17/64-inch diameter is a common size for clearance holes for sheet metal screws and light fasteners, as well as pilot work in mechanical and electrical installations.

Installation Notes

Extra-length drill bits should be installed in a fully tightened chuck before use to prevent slipping or wobble. Reduce feed rate when drilling through hard metals to avoid overheating the cutting edge. Deburr drilled holes before pulling wire or threading pipe through them. Always wear appropriate eye protection when drilling metal or wood.
