Built from high-speed steel (HSS) with a black oxide finish, it carries a 21\/32-inch (0.6562-inch) diameter and a standard 118-degree point angle. The web-thinned, tapered-web geometry reduces thrust load at the tip, making starts more positive and reducing walking on flat stock. At 9 inches overall length with a 5.125-inch flute, it suits deep-hole applications in steel, cast iron, aluminum, and similar materials. Right-hand spiral flutes evacuate chips efficiently during through-hole drilling.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general metalworking and fabrication environments where standard jobber bits lack the reach. Typical applications include structural steel fabrication, machine shops, maintenance and repair operations, and toolroom use. The straight-cylindrical shank seats directly in standard drill chucks and quick-change collet holders without requiring a taper adapter, keeping setup time low. It is sold individually and appropriate for benchtop drill press, radial arm drill, and hand-held drill motor use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/32-inch (0.6562-inch) diameter with matching straight-cylindrical shank for direct chuck mounting\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered-web design for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHSS construction provides toughness across a broad range of ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute promotes consistent chip evacuation in through-hole and blind-hole drilling\u003c\/li\u003e\n\u003cli\u003e9-inch overall length with 5.125-inch flute extends reach beyond standard jobber-length drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style taper length drill bit compatible with standard drill chucks and collet holders accepting a 21\/32-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 a qualified machinist or metalworker familiar with safe drilling practices. Ensure the drill press or drilling machine is powered down and locked out before changing tooling. Secure the workpiece firmly with a vise or clamp — never hold freehand when drilling stock of this diameter. Apply cutting fluid appropriate to the workpiece material to extend tool life and maintain dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/32 inch (0.6562 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 21\/32 inch (0.6562 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\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: 0.67 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.1667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730650169650,"sku":"C.40W.1667","price":71.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/642d951c6bfe59d891e9da23b2539f29.jpg?v=1788720845","url":"https:\/\/voomisupply.com\/products\/hertel-c-40w-1667-taper-length-drill-bit-0-6562-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
