The Thunderbolt design features a 135-degree split point tip that starts cutting on contact, eliminating bit walking without a center punch. The Thunderbolt core construction resists breaking under the torsional stress common in hard-metal applications. This bit is well-suited for use in cordless drills and performs reliably in both shop and field environments. Licensed tradespeople and experienced DIYers working with stainless steel and other hard alloys will find this bit a practical addition to their kit. Each package contains 5 bits.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for specialty drilling applications involving hard metals such as stainless steel, hardened alloys, and similar materials. It is equally usable in corded or cordless drill drivers, making it a versatile option for HVAC technicians, plumbers, electricians, and fabricators who regularly drill through tough substrates during installation or service work. The 1\/8-inch diameter suits pilot holes, sheet metal penetrations, and small-diameter fastener clearance holes across a wide range of trade applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point tip eliminates bit walking and starts cutting immediately on contact\u003c\/li\u003e\n\u003cli\u003eCobalt construction suited for hard metals including stainless steel\u003c\/li\u003e\n\u003cli\u003eThunderbolt core design resists breaking under high torsional load\u003c\/li\u003e\n\u003cli\u003eCompatible with cordless and corded drill drivers\u003c\/li\u003e\n\u003cli\u003eSold in a 5-piece skin-carded package for jobsite convenience\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose cobalt twist drill bit for use in standard 3-jaw drill chucks accepting 1\/8-inch round shanks, compatible with cordless and corded drill drivers across common trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCobalt drill bits in hard metals should be run at lower RPM with steady feed pressure to avoid overheating the cutting edge. Use cutting fluid or a suitable lubricant when drilling stainless steel or other work-hardening alloys to extend bit life. Secure the workpiece firmly before drilling to prevent movement that can break small-diameter bits. Discard any bit showing visible tip damage or excessive heat discoloration before reuse.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Angle\u003c\/strong\u003e: 135 degrees split point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging\u003c\/strong\u003e: Skin carded\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 ELECTRIC TOOL CORP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-2305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51524604559666,"sku":"48-89-2305","price":24.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0602a431556580bbc649b1236b9dfff5.jpg?v=1785452917","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2305-cobalt-drill-bit-1-8-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
