Built with a variable helix geometry that transitions from a 35-degree angle down to 15 degrees, the Red Helix design accelerates chip evacuation and limits heat buildup during cutting. The 135-degree split point tip provides a precise, self-starting entry and prevents the bit from walking across the workpiece surface. Licensed HVAC technicians, pipefitters, electricians, and fabricators working in hard steel, stainless, cast iron, and similar materials will find this bit suited to demanding production and field use.\u003c\/p\u003e\u003cp\u003eThis bit is designed for tough metal applications where standard high-speed steel or black oxide bits fail prematurely. The jobber-length format fits standard 3-jaw keyed and keyless drill chucks. A Chip Breaker geometry reduces heat accumulation during extended drilling runs, and the Secure Grip shank feature helps prevent slippage in the chuck under high torque. Metric sizing is noted on the bit for quick identification on the job. This is a single-piece (each) unit sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix transitions from 35 degrees to 15 degrees for rapid chip removal and reduced heat\u003c\/li\u003e\n\u003cli\u003e135-degree split point tip for self-starting precision entry without walking\u003c\/li\u003e\n\u003cli\u003eChip Breaker geometry decreases heat buildup during sustained drilling\u003c\/li\u003e\n\u003cli\u003eSecure Grip shank minimizes chuck slippage under load\u003c\/li\u003e\n\u003cli\u003eCobalt construction rated for hard metal applications including steel and stainless\u003c\/li\u003e\n\u003cli\u003eMetric sizing marked on the bit for fast field identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length twist drill bit compatible with standard 3-jaw drill chucks for use in all twist drilling applications, with primary suitability for hard metal materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians, pipefitters, HVAC technicians, and metalworkers using a corded or cordless drill or drill press. Secure the shank fully in the chuck before operation and verify chuck key or collar is tightened. Use appropriate cutting fluid when drilling stainless steel or hardened alloys to extend bit life. Inspect the cutting edges for wear before each use and replace if chipping or dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSplit Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle Range\u003c\/strong\u003e: 15 to 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 0045242519484\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: 48-89-2518\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51343177580850,"sku":"48-89-2518","price":15.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310512797.jpg?v=1782019163","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2518-cobalt-jobber-drill-bit-4-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
