The thicker web core provides exceptional strength and resistance to side-load breakage, extending service life under demanding conditions. A 135-degree split point tip starts on contact, eliminating bit walking and improving hole accuracy. The parabolic flute geometry clears chips and debris efficiently, reducing heat buildup and allowing continuous drilling. This bit is well suited for use with portable drills and performs reliably on curved or irregular surfaces.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for professional tradespeople including electricians, plumbers, HVAC technicians, and general contractors who require fast, accurate drilling in metal, wood, and similar materials. The 3-flat Secure-Grip shank holds firmly in standard drill chucks, and the reduced shank diameter allows compatibility with 3\/8-inch chucks, making it practical across a wide range of jobsite drills. It is sold individually and is a strong choice for everyday jobsite drilling tasks where bit longevity and precision startup matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThicker web core resists side-load breakage and extends bit life compared to standard jobber bits\u003c\/li\u003e\n\u003cli\u003e135-degree split point tip starts on contact to prevent walking and improve hole accuracy\u003c\/li\u003e\n\u003cli\u003eParabolic flute design clears chips rapidly to reduce heat and maintain drilling speed\u003c\/li\u003e\n\u003cli\u003e3-flat Secure-Grip shank locks firmly in the drill chuck to reduce slipping\u003c\/li\u003e\n\u003cli\u003eReduced shank diameter fits 3\/8-inch chucks for use with a wide range of portable drills\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides lubricity and corrosion resistance throughout bit life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard portable drills equipped with 3\/8-inch or larger chucks.
