The cobalt alloy raises the heat threshold, allowing the bit to cut efficiently at temperatures exceeding 1,000 degrees F without losing hardness or edge geometry. The 135-degree split point features four cutting edges that bite into the work surface immediately, reducing thrust force and eliminating the bit-walking common with standard 118-degree points. This is a jobber-length bit suited for general-purpose drilling in demanding materials encountered on the job site or in the shop.\u003c\/p\u003e\n\u003cp\u003eThis bit is recommended for drilling in hard metals including heat-treated steel, stainless steel, chrome alloys, manganese steel, titanium, and armor plate. Its cobalt content and split-point geometry make it appropriate for applications where standard HSS bits overheat or dull prematurely. Typical users include HVAC technicians drilling sheet metal enclosures, plumbers working through structural steel, electricians running conduit through hard steel members, and fabricators working with high-alloy stock. The 3\/8-inch shank fits standard 3\/8-inch and 1\/2-inch drill chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 percent cobalt HSS construction maintains cutting performance at temperatures exceeding 1,000 degrees F\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with four cutting edges reduces walking and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eJobber length (6 inches overall) provides reach for most standard drilling applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch reduced shank fits 3\/8-inch and 1\/2-inch drill chucks\u003c\/li\u003e\n  \u003cli\u003eSuitable for heat-treated steel, stainless 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 hard metals including heat-treated steel, stainless steel, chrome, manganese steel, titanium, and armor plate.

Use a drill press or right-angle drill at a controlled, consistent feed rate when possible — intermittent pressure accelerates edge wear. Secure the workpiece before drilling to prevent rotation. Disconnect or de-energize any associated electrical or mechanical system before drilling into live enclosures or structural components per applicable codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\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\u003eCutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-speed steel with 8 percent cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Style\u003c\/strong\u003e: Jobber length\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: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.83 inches x 2.7 inches x 1.85 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: 571307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DISSTON CO","offers":[{"title":"Default Title","offer_id":51698109382962,"sku":"571307","price":56.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f01f3912b3d7a104a8791a05cd9b28a5.jpg?v=1788357836","url":"https:\/\/voomisupply.com\/products\/disston-company-571307-cobalt-hss-drill-bit-1-2x6in-135-split","provider":"Voomi Supply","version":"1.0","type":"link"}
