Built to jobber length with a straight shank, this 9\/64-inch bit measures 2-7\/8 inches in length and features an 8 percent cobalt content that enables sustained cutting efficiency at temperatures exceeding 1,000 degrees F. The 135-degree split point geometry incorporates four cutting edges for aggressive material penetration and eliminates bit walking on contact, reducing the need for a center punch. This bit is suited for use by machinists, pipefitters, and maintenance technicians working in metal fabrication or field service environments.\u003c\/p\u003e\u003cp\u003eThe 197544 is intended for drilling in hard metals where standard HSS bits fall short. Recommended applications include heat-treated steel, stainless steel, chrome alloys, manganese steel, titanium, and armor plate. The cobalt composition sustains hardness under high-heat conditions generated by cutting dense or work-hardening materials, making it a practical choice for production drilling or difficult one-off penetrations in demanding trade environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8 percent cobalt content for heat resistance and cutting efficiency above 1,000 degrees F\u003c\/li\u003e\n\u003cli\u003e135-degree split point with four cutting edges for fast penetration and no walking\u003c\/li\u003e\n\u003cli\u003eHigh speed steel base construction for durability in hard-metal applications\u003c\/li\u003e\n\u003cli\u003eJobber length at 2-7\/8 inches with straight shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eSuitable for stainless steel, titanium, manganese steel, chrome alloys, and armor plate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length straight-shank drill bit compatible with standard 3-jaw drill chucks found on corded and cordless drills, drill presses, and magnetic base drills used in metalworking and trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist, pipefitter, or maintenance technician using a standard drill chuck. Secure the straight shank firmly before operation and verify chuck key is removed prior to powering the tool. Use appropriate cutting fluid or lubricant when drilling stainless steel or titanium to extend bit life and manage heat buildup. Wear appropriate personal protective equipment including eye protection whenever drilling metal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Jobber Length, Straight Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Geometry\u003c\/strong\u003e: 135-degree Split Point, 4 Cutting Edges\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\u003eMaximum Operating Temperature\u003c\/strong\u003e: 1,000 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 197544\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DISSTON CO","offers":[{"title":"Default Title","offer_id":51709368664370,"sku":"197544","price":26.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ca7b5f2d6fd05d724a8ba6ff85e38a9.jpg?v=1788455325","url":"https:\/\/voomisupply.com\/products\/disston-company-197544-cobalt-hss-drill-bit-9-64in-135-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
