The 135-degree split point tip features four cutting edges that initiate penetration quickly and prevent the bit from walking on contact. An 8 percent cobalt content raises the heat tolerance of the steel, allowing efficient cutting at temperatures exceeding 1,000 degrees F. The straight shank seats in standard three-jaw drill chucks. This bit is sized at 1\/16 inch diameter with a 1-7\/8 inch flute length and is sold individually on a card.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for trade and maintenance work where common twist bits fail. Typical applications include drilling into heat-treated steel, stainless steel, chrome alloys, manganese steel, titanium, and armor plate. HVAC techs, plumbers, and electricians reach for cobalt bits when drilling through structural steel, hardened fastener bosses, or thick-gauge stainless enclosures during equipment installation or retrofit work. The jobber length provides a practical reach-to-rigidity balance for hand drill and drill press use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point with four cutting edges for fast starts and no walking\u003c\/li\u003e\n  \u003cli\u003e8 percent cobalt content delivers heat resistance beyond 1,000 degrees F\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel base material resists wear during prolonged hard-metal drilling\u003c\/li\u003e\n  \u003cli\u003eJobber length balances reach and rigidity for general-purpose drilling tasks\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRecommended for stainless steel, heat-treated steel, titanium, manganese steel, chrome alloys, and armor plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard three-jaw drill chucks on hand drills and drill presses where a 1\/16 inch straight-shank cobalt drill bit is required for hard-metal applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCobalt drill bits should be used with appropriate cutting fluid or lubricant when drilling stainless steel or other work-hardening alloys to extend bit life and reduce heat buildup. Secure the workpiece firmly before drilling to prevent movement and bit breakage at this small diameter. Use steady, moderate feed pressure and allow the cutting edges to work without forcing the bit. Dispose of worn bits per applicable shop safety practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-7\/8 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\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 length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.75 inches x 1.85 inches x 0.98 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 571190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DISSTON CO","offers":[{"title":"Default Title","offer_id":51695306408242,"sku":"571190","price":18.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72f3eca4d7cb2b4fcdcc826d770c777b.jpg?v=1788333724","url":"https:\/\/voomisupply.com\/products\/disston-company-571190-cobalt-hss-drill-bit-1-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
