Measuring 1.5 inches in diameter with a 7.5-inch overall length, this bit is shorter than a jobber-length drill, providing increased rigidity and reduced deflection in close-clearance setups such as drill presses, turret lathes, and CNC machine tools. The 118-degree point angle is the standard geometry for drilling into mild steel, aluminum, brass, and similar workpiece materials. The bright, uncoated high-speed steel construction suits general shop use where coolant application or manual resharpening is part of routine maintenance.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production machining, job shop work, and maintenance repair operations where a large-diameter, short-length drill is needed. The screw machine length format is commonly specified when spindle clearance is limited or when a stiffer tool setup is required to hold dimensional accuracy. It cuts in the right-hand direction and is appropriate for use in any standard right-hand spindle machine. Metalworking shops, industrial maintenance technicians, and tool-and-die operations are the primary users of this size and style.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.5-inch diameter screw machine length format for increased rigidity over jobber-length equivalents\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle suits general-purpose drilling in mild steel, aluminum, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction allows resharpening and tolerates moderate heat buildup\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with cutting oils and water-soluble coolants\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction fits all standard right-hand spindle machines\u003c\/li\u003e\n  \u003cli\u003e4.875-inch flute length provides adequate chip evacuation for the full depth of cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit for use in drill presses, lathes, and CNC machine tools accepting a 1.5-inch shank or requiring a large-diameter short-length drill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or maintenance technicians familiar with large-diameter drilling operations. Secure the bit firmly in an appropriate chuck or collet rated for the shank diameter before operating the spindle. Power down and de-energize the machine completely before changing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.5 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\u003eFlute Length\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.40N.3810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747557507378,"sku":"C.40N.3810","price":369.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54fc7d4adfd86d7ff778a1b090f099bb.jpg?v=1788882532","url":"https:\/\/voomisupply.com\/products\/hertel-c-40n-3810-screw-machine-drill-bit-1-1-2-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
