Built with a variable helix geometry that transitions from an aggressive 35-degree cutting angle down to 15 degrees, this bit promotes rapid chip evacuation and limits heat buildup during extended drilling cycles. The 135-degree split point tip starts on contact without a center punch and prevents walking, delivering fast and accurate hole placement. Licensed tradespeople and metalworking contractors who drill through stainless, hardened steel, and other tough alloys will find this bit suited to the task. It is sold individually and sized in metric.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in hard metal applications including stainless steel, high-alloy steel, cast iron, and similar tough materials encountered in industrial, fabrication, and field service work. The jobber-length format makes it compatible with standard drill chucks and magnetic drill presses in both shop and on-site environments. The metric sizing makes it a practical addition to service kits where metric hole specifications are required. It can also be used in general-purpose twist drilling applications when durability and bit life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix design transitions from 35 degrees to 15 degrees for rapid chip removal and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact and prevents bit walking without a center punch\u003c\/li\u003e\n\u003cli\u003eCobalt construction rated for up to 10 times the service life compared to black oxide drill bits\u003c\/li\u003e\n\u003cli\u003eChip breaker geometry further limits heat accumulation during prolonged cuts\u003c\/li\u003e\n\u003cli\u003eSecure-grip shank design reduces slipping inside the chuck during high-torque drilling\u003c\/li\u003e\n\u003cli\u003eMetric sizing for applications requiring precise metric hole diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length cobalt twist drill bit suitable for use with standard 3-jaw drill chucks and compatible drilling equipment in hard metal applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, fabricators, and trade professionals using standard drill presses, hand drills, or magnetic base drills. Secure the bit firmly in the chuck before drilling and verify chuck key is removed before powering the tool. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and manage heat. Do not apply side pressure to the bit during drilling, as cobalt bits can fracture under lateral loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Length\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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\u003eHelix Angle Range\u003c\/strong\u003e: 15 to 35 degrees variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizing System\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 045242519354\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: 48-89-2505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51346308235570,"sku":"48-89-2505","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310512660.jpg?v=1782077063","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2505-cobalt-jobber-drill-bit-2-4in-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
