The Thunderbolt design uses a thicker web core than standard bits to resist side-load breakage and extend service life. A 135-degree split point tip starts on contact without walking, delivering fast and accurate hole placement. The parabolic flute geometry clears chips quickly to reduce heat buildup and keep cuts moving. This bit is suited for electricians, plumbers, HVAC technicians, and general tradespeople who drill frequently through metal, wood, and PVC using portable drills.\u003c\/p\u003e\u003cp\u003eThe 48-89-2729 is intended for jobsite drilling applications across residential and light commercial work. The 3-flat Secure-Grip shank locks firmly in drill chucks to prevent slipping under load. A reduced shank diameter allows use in 3\/8-inch chucks, making this bit compatible with a wide range of portable drills commonly found on trade jobsites. The black oxide coating provides lubricity during cutting and resists corrosion during storage and repeated use. It ships individually and is well suited to high-frequency drilling tasks where bit longevity matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point tip starts on contact and prevents walking for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eThicker web core resists side-load breakage and extends bit life compared to standard jobber bits\u003c\/li\u003e\n\u003cli\u003eParabolic flute design clears chips rapidly to reduce heat and maintain cutting speed\u003c\/li\u003e\n\u003cli\u003e3-flat Secure-Grip shank prevents slipping in drill chucks under heavy load\u003c\/li\u003e\n\u003cli\u003eReduced shank diameter fits 3\/8-inch chucks for compatibility with a wide range of portable drills\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating adds lubricity and corrosion resistance for extended storage life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch and larger keyed or keyless drill chucks.

Ensure the drill is powered off and the chuck is fully tightened before beginning any drilling operation. When drilling metal, use appropriate cutting fluid to reduce heat and prolong bit life.
