It measures 19\/64 inch (0.2969 inch decimal) in diameter with an overall length of 4-3\/8 inches and a flute length of 3-1\/16 inches. The 135-degree split point reduces walking on contact and lowers thrust requirements when starting a hole in hard or work-hardened materials. An oxide and gold coating provides added surface hardness and lubricity. This bit is installed and used by machinists, pipefitters, HVAC technicians, and electricians working with ferrous metals, stainless steel, and other hard alloys.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand drilling operations in residential and commercial trade applications where standard high-speed steel bits wear prematurely. The straight cylindrical shank fits standard 3-jaw drill chucks on corded drills, drill presses, and magnetic base drills. With a 5xD flute-to-diameter ratio, it handles moderate chip evacuation in through-hole and blind-hole drilling. It is packaged individually and ships as a quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for drilling hard and abrasive metals including stainless steel and high-alloy materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers feed force at hole start\u003c\/li\u003e\n  \u003cli\u003eOxide and gold coating improves surface lubricity and extends tool life\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with regular helix promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for use with conventional forward-rotation drilling equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber-length drill bit compatible with standard 3-jaw drill chucks accepting a straight cylindrical shank in the 0.2500 to 0.3000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the drill chuck and verify chuck key is removed before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve hole quality. Operators should wear ANSI-rated eye protection during all drilling operations. Allow the bit to cool between cuts when working in hard alloys to prevent heat buildup that can soften the cutting edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/64 inch (0.2969 inch)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/8 inches (4.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/16 inches (3.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732862206258,"sku":"42003","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fd7e5874f6fe1a5b82f2e887227cff.jpg?v=1788747677","url":"https:\/\/voomisupply.com\/products\/hertel-42003-cobalt-jobber-drill-bit-19-64-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
