It carries a 29\/64-inch (0.4531-inch) diameter with a 118-degree standard point angle ground from high-speed steel (HSS). The black oxide finish reduces friction and provides light corrosion resistance during cutting. Web thinning at the tip reduces thrust force and improves chip clearance, which matters when drilling tougher ferrous materials. This drill is sized and built for use by machinists, tool-and-die workers, and maintenance technicians who need consistent, repeatable results in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis bit suits applications in general metalworking where a longer flute length is required to reach deeper hole depths than a standard jobber-length drill allows. The 4.75-inch flute length and 7.5-inch overall length give clearance for deeper bores without requiring extensions. The straight cylindrical shank seats directly in a standard drill chuck, making it compatible with drill presses, milling machines, and hand-held power tools with appropriate chuck capacity. Right-hand cut spiral flutes evacuate chips efficiently during through-hole and blind-hole operations in steel, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e29\/64-inch (0.4531-inch) diameter with a standard 118-degree split point angle\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a wide range of ferrous materials\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces friction and provides light rust resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003e4.75-inch flute length supports deeper hole depths than standard jobber drills\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style taper length drill bit suitable for use in standard drill chucks, drill presses, and milling machine spindles capable of accepting a 29\/64-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with proper speeds and feeds for HSS tooling in metal. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 29\/64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.4531 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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: 29\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.5 inches\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: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C.40W.1151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738864615730,"sku":"C.40W.1151","price":38.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70398d8d7f8b768dee6d60a7903502ab.jpg?v=1788805775","url":"https:\/\/voomisupply.com\/products\/hertel-c-40w-1151-taper-length-drill-0-4531-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
