Built to a wire gauge size of 51 with a decimal equivalent of 0.0670 inches, this bit features a 135-degree split point that reduces walking on entry and lowers thrust force required during drilling. The right-hand cutting direction and regular spiral flute geometry suit it to production and maintenance drilling in ferrous metals, stainless steel, and other tough alloys. At 1-11\/16 inches overall length, the screw machine format provides added rigidity over jobber-length bits, making it well suited for close-quarter drilling and drill press work.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in metalworking applications across manufacturing, maintenance, and repair environments. The short, rigid body performs well in screw machines, CNC machining centers, and bench-top drill presses where tool deflection must be minimized. Its heavy-duty grade cobalt construction handles interrupted cuts and high-heat applications that would degrade standard M2 high-speed steel tooling. Licensed machinists, tool and die workers, and maintenance mechanics are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides heat and wear resistance for drilling hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking on entry without a center punch\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body adds rigidity and reduces deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade rating suited for production drilling and high-cycle maintenance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock tooling selection for screw machine and drill press operations requiring a wire gauge size 51 straight-shank drill bit with a 0.0670-inch cutting diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance mechanics. Secure the straight shank firmly in a drill chuck or collet before use and verify runout is within acceptable limits for the application. Follow applicable shop safety procedures, including appropriate eye protection and chip guarding. Do not exceed the recommended cutting speed and feed rate for the workpiece material, as overheating will degrade cobalt tooling performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01378512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714157969714,"sku":"01378512","price":47.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c69e91ddd3907143f41fec02178f76cf.jpg?v=1788496969","url":"https:\/\/voomisupply.com\/products\/value-collection-01378512-cobalt-drill-bit-size-51","provider":"Voomi Supply","version":"1.0","type":"link"}
