Built from high-speed steel with a bright finish, this bit measures 1\/2 inch in diameter and 16 inches in overall length, making it well suited for deep boring in wall cavities and floor assemblies. The 1\/4-inch hex shank provides a secure, slip-resistant connection in compatible chuck systems. Electricians and plumbers routinely reach for this style of bit when running wire or pipe through structural members.\u003c\/p\u003e\u003cp\u003eThe 88708 fits residential and light commercial rough-in work where extended reach is required. Its 16-inch overall length allows drilling through thick assemblies without requiring a bit extension. The 1\/4-inch hex shank seats in quick-change chuck systems and standard keyless chucks. This bit is a practical choice for electricians fishing wire, plumbers routing pipe paths, and HVAC techs drilling for low-voltage or refrigerant line penetrations through wood members.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2 inch cutting diameter for standard rough-in hole sizing\u003c\/li\u003e\n\u003cli\u003e16 inch overall length for deep boring in wall and floor assemblies\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability through wood materials\u003c\/li\u003e\n\u003cli\u003e1\/4 inch hex shank for secure fit in quick-change and standard chuck systems\u003c\/li\u003e\n\u003cli\u003eTwo-spur tip geometry for cleaner entry and reduced tear-out\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating buildup that could affect dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard spade blade drill bit compatible with drills and right-angle drill attachments accepting a 1\/4 inch hex shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit is performed by electricians, plumbers, and HVAC technicians during rough-in phases.
