The bit is constructed from cobalt alloy, which extends service life by up to 15 times compared to black oxide drill bits. A variable helix design with an aggressive 35-degree helix angle transitioning to 15 degrees accelerates material extraction and reduces heat buildup. The 135-degree split point tip starts on contact without walking, delivering accurate, consistent holes. An enhanced tapered web reinforces the core for added flute durability under heavy-feed conditions.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling hard metals, PVC, and wood in both residential and commercial trade applications. Electricians, HVAC technicians, plumbers, and general contractors reach for cobalt bits when working through steel strut, box frames, schedule pipe flanges, or other ferrous materials that defeat standard bits. The 3-flat shank keeps the bit seated securely in a standard chuck and prevents slippage during high-torque drilling. It is sold individually, making it a practical replacement or add-on to an existing cobalt set.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt alloy construction provides up to 15X life versus black oxide drill bits in hard metal\u003c\/li\u003e\n\u003cli\u003eVariable helix design transitions from 35-degree to 15-degree angle for rapid chip extraction\u003c\/li\u003e\n\u003cli\u003e135-degree split point tip starts on contact and prevents bit walking\u003c\/li\u003e\n\u003cli\u003eEnhanced tapered web strengthens the core and increases flute durability\u003c\/li\u003e\n\u003cli\u003e3-flat shank locks securely in chuck to prevent slippage under torque\u003c\/li\u003e\n\u003cli\u003eRated for hard metals, PVC, and wood\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length cobalt twist drill bit for use in standard keyed and keyless drill chucks accepting a 3-flat shank; suitable for corded drills, cordless drills, and drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCobalt drill bits should be installed by securing the 3-flat shank fully into the chuck before tightening. Always wear appropriate eye protection when drilling metal. Apply consistent feed pressure and use a cutting fluid or lubricant when drilling hard metals to reduce heat and extend bit life. Inspect the bit tip for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Size\u003c\/strong\u003e: 5\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.01 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.7 x 1.85 x 0.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees (transitions to 15 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees split point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 48-89-2302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51346153537842,"sku":"48-89-2302","price":22.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310512643.jpg?v=1782072323","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2302-cobalt-drill-bit-5-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
