Built with a 5\/8 inch diameter tip and a 1\/2 inch reduced parallel shank, this bit fits standard 1\/2 inch drill chucks while delivering the cutting capacity of a larger diameter tool. The 3-flute geometry promotes chip evacuation and helps maintain cutting efficiency under load. The Silver Deming construction provides high resistance to abrasion, extending tool life in demanding production and maintenance drilling applications. Machinists, millwrights, and maintenance technicians rely on this style of bit for accurate large-diameter hole work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for jobber-length drilling operations requiring a 4 inch depth of cut with a 6 inch overall length. The reduced 1\/2 inch shank makes it compatible with standard drill presses, magnetic drills, and hand-held corded drills equipped with a 1\/2 inch chuck. Typical applications include fabrication shops, industrial maintenance, HVAC rough-in work requiring large-diameter penetrations, and general metalworking where oversized chuck capacity is not available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for abrasion resistance in metal drilling\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch cutting diameter with 1\/2 inch reduced parallel shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e3-flute design promotes chip clearing and consistent cutting performance\u003c\/li\u003e\n  \u003cli\u003e4 inch depth of cut with 6 inch overall length for jobber-length applications\u003c\/li\u003e\n  \u003cli\u003eSilver Deming style — allows large-diameter drilling without a dedicated large-chuck machine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length Silver Deming style drill bit compatible with any 1\/2 inch keyed or keyless drill chuck on drill presses, magnetic base drills, and heavy-duty hand drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this bit is performed by machinists, millwrights, or experienced technicians using a drill press or hand-held drill with a 1\/2 inch chuck. Secure the reduced shank fully into the chuck before operation and verify the chuck is tightened properly on all jaws. Use cutting fluid or cutting oil when drilling ferrous metals to extend bit life and improve hole quality. Always wear appropriate eye protection and secure the workpiece before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch reduced parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Silver Deming Jobber Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 086071915405\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: 091540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51345215193394,"sku":"091540","price":45.31,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538528.jpg?v=1782051742","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-091540-hss-silver-deming-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
