Built to jobber length at 3\/16 inch diameter and 3-1\/2 inches overall length, it features an 8 percent cobalt content that delivers sustained heat resistance at temperatures exceeding 1,000 degrees Fahrenheit. The 135-degree split point geometry incorporates four cutting edges for fast penetration and self-centering action, eliminating the need for a center punch or pilot hole. This bit is suited for trade professionals who regularly drill through materials that destroy standard HSS tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is recommended for use in heat-treated steel, stainless steel, chrome, manganese steel, titanium, and armor plate. It is a practical choice for HVAC installers, pipefitters, electricians, and fabricators working with hard-metal substrates in both field and shop environments. The straight shank accepts standard three-jaw drill chucks, making it compatible with common corded and cordless drill drivers used in trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 percent cobalt content provides heat resistance above 1,000 degrees Fahrenheit for extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with four cutting edges for fast, self-centering penetration without walking\u003c\/li\u003e\n  \u003cli\u003eJobber-length geometry balances reach and rigidity for general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard three-jaw chucks on corded and cordless drills\u003c\/li\u003e\n  \u003cli\u003eRated for heat-treated steel, stainless steel, chrome, manganese steel, titanium, and armor plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling in hard metals including heat-treated steel, stainless steel, chrome, manganese steel, titanium, and armor plate.

Apply cutting fluid or lubricant when drilling stainless steel or titanium to extend bit life and improve cut quality. Secure the workpiece firmly before drilling to prevent movement. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\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\u003eCobalt Content\u003c\/strong\u003e: 8 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel with Cobalt (HSS-Co)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Style\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 1,000 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.75 inches x 1.85 inches x 2.24 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DISSTON COMPANY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 571240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DISSTON CO","offers":[{"title":"Default Title","offer_id":51692067193138,"sku":"571240","price":24.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9de72eb38090eed99f69bd8ea5b6c2b.jpg?v=1788292624","url":"https:\/\/voomisupply.com\/products\/disston-company-571240-cobalt-drill-bit-3-16-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
