With a 7\/16-inch tip diameter and an overall length of 5.5 inches, this bit fits the standard jobber-series profile trusted across metal fabrication, maintenance, and industrial service work. The HSS construction allows the cutting edge to retain hardness at elevated temperatures, making it suitable for ferrous metals, cast iron, and similar hard surfaces. Machinists, pipefitters, ironworkers, and general maintenance technicians are the primary users of this style of bit.\u003c\/p\u003e\u003cp\u003eThis bit is sized and proportioned for general-purpose production drilling in shop and field environments. The jobber-length format offers a balance of reach and rigidity, making it well-suited for handheld drill motors, drill presses, and magnetic base drills. A 4-inch depth of cut supports most through-hole and blind-hole applications encountered in structural, mechanical, and maintenance work. It is sold as a single unit and fits standard chuck configurations accepting 7\/16-inch shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction retains cutting edge hardness under elevated heat and pressure\u003c\/li\u003e\n\u003cli\u003e7\/16-inch tip diameter with a 4-inch depth of cut for controlled material removal\u003c\/li\u003e\n\u003cli\u003e5.5-inch overall length in standard jobber-series proportioning for rigidity and reach\u003c\/li\u003e\n\u003cli\u003eCompatible with handheld drill motors and stationary drill presses accepting this shank size\u003c\/li\u003e\n\u003cli\u003eDesigned for hard surfaces including ferrous metals and similar materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length HSS drill bit suitable for use in any 3-jaw chuck or drill press that accepts a 7\/16-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit is performed by machinists, ironworkers, maintenance technicians, and other qualified trades. Secure the bit firmly in the chuck and verify it is seated true before beginning any drilling operation. Always wear appropriate eye protection and use a cutting fluid or lubricant when drilling into ferrous metals to extend bit life and reduce heat buildup. Ensure the workpiece is clamped or secured before applying feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 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\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 086071100283\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: 010028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51343095824690,"sku":"010028","price":67.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538373.jpg?v=1782016432","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-010028-hss-jobber-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
