It measures 1-11\/16 inches (1.6875 inches decimal) in diameter with an 8-inch overall length and a 5-1\/8-inch flute length. The 118-degree split-free point angle suits general-purpose drilling in a wide range of materials. Constructed from high-speed steel with a bright, uncoated finish, this bit is a standard choice for machinists, tool-and-die technicians, and maintenance professionals working on production or job-shop equipment.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are shorter than jobber-length bits, which increases rigidity and reduces deflection during drilling. This makes the C.40N.4286 well suited for use in drill presses, CNC machining centers, turret lathes, and screw machines where stub-length tooling is preferred for accuracy and chatter reduction. It is rated for general-purpose drilling applications on materials in the 0.6000-inch-and-above diameter size range, and fits standard drill chucks and collet holders that accept 1-11\/16-inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-11\/16 inch (1.6875 inch) diameter for large-bore general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle for broad material compatibility\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of metals\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows easy visual inspection of the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length increases rigidity and reduces bit deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for use in standard forward-rotating spindles\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 compatible with drill presses, CNC lathes, turret lathes, and screw machines equipped with chucks or collet holders sized for 1-11\/16-inch diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by a qualified machinist or tooling technician familiar with proper spindle speeds and feed rates for the workpiece material. Secure the bit fully in the chuck or collet before powering the spindle. Always wear appropriate eye protection and ensure the workpiece is clamped securely before drilling. Do not exceed the spindle speed rating of the machine or the recommended cutting parameters for the specific material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-11\/16 inches (1.6875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5-1\/8 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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.4286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735629726002,"sku":"C.40N.4286","price":369.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a7ab564df6bea7149d6cc4be192f207.jpg?v=1788773366","url":"https:\/\/voomisupply.com\/products\/hertel-c-40n-4286-screw-machine-drill-bit-1-11-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
