The stub-length body offers increased rigidity compared to standard-length drills, reducing deflection and improving hole accuracy in tough materials. Cobalt construction provides enhanced heat resistance and durability when drilling hard metals such as stainless steel, cast iron, and high-strength alloys. This drill is suited for machinists, pipefitters, electricians, and HVAC technicians who regularly drill through hard substrates on the job.\u003c\/p\u003e\u003cp\u003eThe SC400-021-I is appropriate for use in both shop and field environments where a 21\/64 inch hole diameter is required. The stub-length profile makes it a preferred choice in tight-clearance drilling situations where a full-length drill would be impractical. It is well suited for drilling pilot holes, clearance holes, and tapping preparation holes in ferrous and non-ferrous metals across residential, commercial, and light industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/64 inch diameter for precise hole sizing in metal work\u003c\/li\u003e\n\u003cli\u003eCobalt construction delivers superior heat and wear resistance over standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eStub-length body increases rigidity and reduces bit deflection during drilling\u003c\/li\u003e\n\u003cli\u003eSuitable for hard metals including stainless steel and high-strength alloys\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 for flexible purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub drill replacement compatible with standard drill chucks and drilling equipment accepting 21\/64 inch shank sizes across trade and industrial drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCobalt stub drills should be installed in a properly rated drill press, handheld drill, or drill driver with a compatible chuck rated for the shank diameter. Secure the workpiece firmly before drilling to prevent movement and bit breakage. Use appropriate cutting fluid when drilling hard metals to extend bit life and maintain hole quality. Follow applicable workplace safety standards including eye protection and secure workholding practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 21\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Type\u003c\/strong\u003e: Stub Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC400-021-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233954922802,"sku":"SC400-021-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623821.png?v=1780113051","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-sc400-021-i-cobalt-stub-drill-21-64","provider":"Voomi Supply","version":"1.0","type":"link"}
