Built from high speed steel with a cobalt oxide bronze finish, it features a 135-degree split point and a web-thinned, tapered web design that reduces thrust and improves centering on hard materials. The straight-cylindrical shank measures 0.1065 inches in diameter, and the overall length is 2.5 inches. Two spiral flutes in a regular helix pattern clear chips efficiently during right-hand cutting operations. This bit meets NAS 907 specification and is suited for general-purpose drilling in demanding trade and production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The cobalt content in the high speed steel base provides heat resistance that makes it appropriate for harder and more abrasive workpiece materials where standard HSS bits would dull quickly. The flute length of 0.8125 inches supports a maximum drilling depth of 0.8125 inches per pass. It fits standard drill chucks used by machinists, pipefitters, ironworkers, and maintenance technicians in both shop and field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 36 size — 0.1065 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves cutting efficiency on hard alloys\u003c\/li\u003e\n  \u003cli\u003eCobalt oxide bronze finish adds heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eListed under Series R88CO-R89CO.

Secure the straight-cylindrical shank firmly in the chuck before operation and confirm chuck key is removed prior to starting the machine. No coolant-through capability is present on this bit; use an appropriate cutting fluid applied externally when drilling stainless steel, titanium, or other heat-sensitive alloys. Follow applicable shop safety procedures and machine manufacturer guidelines for spindle speed selection based on workpiece material and bit diameter.\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: No. 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1065 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Cobalt Oxide Bronze\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: Standard Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1065 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6875 inches (1-11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R88CO-R89CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999824\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693167903026,"sku":"5999824","price":70.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3a5c855eb0082eb4dbe390928486b2a.jpg?v=1788308300","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999824-cobalt-drill-bit-no-36","provider":"Voomi Supply","version":"1.0","type":"link"}
