It measures 0.1406 inches (9\/64 inch) in diameter with a 118-degree standard point angle and is manufactured from high-speed steel (HSS) with a black oxide finish. The black oxide coating reduces friction and provides light corrosion resistance during use. At 5.375 inches overall length with a 3.0 inch flute length, this taper length drill reaches deeper than a jobber-length bit, making it suitable for applications where additional reach is required. It is a right-hand cut, spiral flute design with a web-thinned, tapered web configuration for easier starting and reduced thrust.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in metalworking, maintenance, and fabrication environments. The taper length format is commonly selected when standard jobber-length bits cannot reach the workpiece or when drilling through thicker stock. It is suitable for use in drill presses, CNC machining centers, and hand-held power drills with appropriate collets or chucks. Typical users include machinists, millwrights, and maintenance technicians working on ferrous and non-ferrous metals. The straight-cylindrical shank seats directly in standard drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1406 inch (9\/64 inch) diameter with straight-cylindrical shank for standard chuck mounting\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned geometry for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003e3.0 inch flute length provides extended reach compared to jobber-length equivalents\u003c\/li\u003e\n\u003cli\u003eHSS construction maintains hardness and edge retention at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces friction and provides light corrosion protection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard taper length drill bit with a straight-cylindrical shank, compatible with any drill chuck or collet accepting a 9\/64 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool practices. Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and secure the workpiece before beginning the cut. Do not exceed the recommended speed and feed range for the material being drilled; consult published HSS cutting speed tables for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1406 inches (9\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.375 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\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: 0.2 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.0357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746465251634,"sku":"C.40W.0357","price":16.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dd228d543ce1d5c4a5c0d49d990afcc.jpg?v=1788870537","url":"https:\/\/voomisupply.com\/products\/hertel-c-40w-0357-taper-length-drill-9-64-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
