The cobalt alloy construction delivers improved heat resistance and edge retention, making it a practical choice for ferrous metals, stainless steel, and other tough materials. With a 3\/16-inch tip diameter and a 4-inch depth of cut, this straight-shank bit is suited to production drilling and maintenance applications that demand consistent performance under load. It ships as a single unit and is the type of tooling favored by machinists and trade professionals working on metal fabrication or mechanical assembly tasks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in standard drill presses, magnetic drills, or heavy-duty hand drills equipped with a keyed or keyless chuck accepting straight-shank bits. The 3\/16-inch diameter and 4-inch depth of cut make it appropriate for through-hole and deep-hole work in hard metals encountered in industrial maintenance, mechanical contracting, and fabrication shops. It is sold individually, allowing technicians to stock specific sizes without purchasing a full index set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS cobalt construction provides superior heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty straight shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eType J jobber-length geometry balances reach and rigidity for general-purpose deep drilling\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch diameter with 4-inch depth of cut handles a wide range of through-hole and blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging allows precise inventory control for specific drill sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length straight-shank drill bit compatible with standard keyed and keyless drill chucks accepting 3\/16-inch shank tooling in drill presses and portable drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this drill bit is performed by machinists or qualified trade professionals. Secure the straight shank firmly in the chuck and verify concentricity before beginning a cut. Always use appropriate cutting fluid or coolant when drilling hard metals to protect the cutting edge and reduce heat buildup. Follow applicable shop safety practices and wear proper personal protective equipment when operating drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 3\/16 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: 3.5 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: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 086071103123\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 010312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51345401250098,"sku":"010312","price":57.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538453.jpg?v=1782057170","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-010312-hss-cobalt-jobber-drill-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
