Built with a straight shank and Type J jobber geometry, this drill delivers consistent performance in demanding trade applications. The 3\/8 inch tip diameter and 4 inch depth of cut make it suited for structural, fabrication, and maintenance work where standard HSS tooling falls short. Overall length is 5 inches. Weighing 0.75 pounds, it is a solid, purpose-built tool for machinists, pipefitters, ironworkers, and maintenance mechanics working with hard ferrous metals and alloys.\u003c\/p\u003e\u003cp\u003eThis cobalt jobber drill is used in applications where elevated heat resistance and edge retention are critical. Typical use cases include drilling into stainless steel, hardened steel, cast iron, and other tough ferrous materials encountered in industrial fabrication shops, mechanical rooms, and field service environments. The Type J jobber length configuration makes it compatible with standard drill chucks on bench drills, magnetic drills, and hand-held power drills used across multiple trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS cobalt construction for superior heat resistance and durability in hard materials\u003c\/li\u003e\n\u003cli\u003eType J jobber geometry with straight shank for broad chuck compatibility\u003c\/li\u003e\n\u003cli\u003e3\/8 inch diameter tip for common structural and mechanical drilling tasks\u003c\/li\u003e\n\u003cli\u003e4 inch depth of cut suitable for through-drilling in typical stock thicknesses\u003c\/li\u003e\n\u003cli\u003e5 inch overall length fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eHeavy-duty designation for use where standard HSS drills wear prematurely\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a straight-shank jobber drill compatible with standard 3\/8 inch and larger keyed or keyless drill chucks on bench, magnetic, and handheld power drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of drill bits should be performed by qualified tradespeople following safe tooling practices. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Use appropriate cutting fluid when drilling hard ferrous metals to extend tool life and maintain bit geometry. Inspect the cutting edge for wear or chipping before each use and replace if the edge is degraded.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Type\u003c\/strong\u003e: Type J Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 010324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51347351503154,"sku":"010324","price":82.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538460.jpg?v=1782102310","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-010324-hss-cobalt-jobber-drill-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
