Built under the Thunderbolt line, it features a thicker-than-standard web core that resists side load breakage during aggressive drilling. The 135-degree split point tip starts on contact without walking, and a parabolic flute geometry evacuates chips quickly to reduce heat buildup and extend cutting life. The 3-flat Secure-Grip shank locks firmly in chuck jaws and resists slipping under torque. At 4.5 inches overall with 3.1875 inches of cutting depth, this bit handles jobsite drilling in metal, wood, and PVC with reduced feed pressure.\u003c\/p\u003e\u003cp\u003eThis bit is suited for electricians, plumbers, HVAC installers, general contractors, and maintenance technicians who drill frequently into steel, structural wood, conduit knockout reinforcements, and plastic pipe. The parabolic flute and split point combination makes it effective on curved and irregular surfaces where standard bits tend to skate. It is optimized for use with portable corded and cordless drill drivers and hammer drills in rotary-only mode. The 6-bit pack supports ongoing site work where bit replacement is a routine cost of operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point tip starts on contact and prevents walking on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003eThicker web core provides greater resistance to side load breakage compared to standard jobber bits\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry clears chips fast to reduce heat and extend bit life\u003c\/li\u003e\n\u003cli\u003e3-flat Secure-Grip shank prevents chuck slippage under high torque\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eCuts metal, wood, and PVC with reduced drilling effort\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3-jaw drill chucks on portable corded and cordless drills.

Always wear eye protection when drilling metal or plastic. For metal drilling, use a cutting fluid to reduce heat at the tip and extend bit life. Inspect bits for tip wear or shank damage before each use and replace any bit showing cracks or significant point rounding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size (Fraction)\u003c\/strong\u003e: 5\/16 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size (Decimal Inch)\u003c\/strong\u003e: 0.3125 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Materials\u003c\/strong\u003e: Metal, Plastic, Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Imperial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 6 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-2836\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51138581070130,"sku":"48-89-2836","price":29.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532866.jpg?v=1778259466","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2836-thunderbolt-5-16-in-hss-jobber-drill-bit-6-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
