Titan Usa CD68617 Extra Length Drill Bit 17/64 in Hss

Product Description

The TITAN USA CD68617 is a high speed steel extra length drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. With a 17/64 inch (0.2656 inch) diameter and a 12 inch overall length, this bit handles extended-reach work in metal, wood, and plastic without requiring a drill extension. The 118-degree standard point provides positive centering on most common materials. Two right-hand spiral flutes run 9 inches in length, efficiently evacuating chips during deep cuts. Licensed trades and industrial shops working on long-reach structural or mechanical drilling tasks rely on bits in this class for consistent results in confined or extended-depth bores.

This extra length drill bit is suited for residential and commercial applications where standard drill bits fall short. Typical uses include drilling through deep structural members, pipe hangers, HVAC ductwork framing, electrical panel knockouts in thick assemblies, and long-reach fastener pilot holes in mechanical rooms or tight wall cavities. The straight-cylindrical shank accepts standard three-jaw drill chucks across a wide range of corded and cordless drill drivers and drill presses commonly used by electricians, plumbers, HVAC technicians, and general construction tradespeople.

Key Features

• 17/64 inch diameter with matching 17/64 inch straight-cylindrical shank for secure chuck grip
• 12 inch overall length provides extended reach for deep structural drilling
• 9 inch flute length maximizes chip evacuation during long-depth passes
• 118-degree standard point angle for reliable self-centering on common materials
• Two right-hand spiral flutes for efficient chip clearance and reduced heat buildup
• Uncoated high speed steel construction — easy to resharpen in the field

Compatibility

Designed as an OEM-style replacement or upgrade extra length drill bit fitting any standard three-jaw drill chuck sized for 17/64 inch shanks, consistent with Series 686 tooling specifications.

Installation Notes

Extra length drill bits should be installed in a properly rated drill chuck and tightened securely before use to prevent slippage during deep cuts. Reduce feed pressure and RPM compared to standard-length bits to minimize deflection and heat buildup over the extended length. Periodically withdraw the bit during deep cuts to clear chips from the flutes and prevent binding. Inspect the cutting edges before each use and resharpen or replace when dulling is observed to maintain safe, accurate drilling.
