Built from heavy-duty high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in ferrous and non-ferrous materials. The 135-degree split point starts on contact without center-punching and reduces walking on flat surfaces. Overall length is 2-1\/8 inches with a 1-1\/16-inch flute length, keeping the tool rigid in short-reach setups. The straight-cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\n\u003cp\u003eScrew machine length bits are the shortest standard drill format, making them the preferred choice where rigidity matters most — production drilling, gang drilling fixtures, drill press work, and CNC applications where chatter and deflection must be minimized. The 11\/64-inch diameter (0.1719 inches decimal) and regular spiral flute geometry suit through-hole and blind-hole drilling in steel, aluminum, brass, and similar materials. Licensed electricians, machinists, HVAC fabricators, and plumbing trades reach for this format when working in tight quarters or drilling sheet metal and strut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-starting contact and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends cutting edge life and lowers heat buildup\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty HSS construction rated for continuous production use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web for improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n  \u003cli\u003eScrew machine length format maximizes rigidity and reduces deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard screw machine length drill bit for use in drill presses, CNC machining centers, hand drills, and gang drilling fixtures accepting a straight-cylindrical shank in the 11\/64-inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully into the chuck and verify concentricity before starting the cut. No coolant-through capability is present, so apply cutting fluid externally when drilling hard steels to prevent premature edge wear. Follow shop safety protocols and OSHA machine guarding requirements when operating drill presses or powered hand tools. Inspect the cutting edge for wear or chipping before each use and replace the bit rather than re-sharpening TiN-coated edges, as re-grinding removes the coating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/64 inches (0.1719 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 2386746\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728682352946,"sku":"2386746","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f89c8bbbd62aea4a306aabb726a65ded.jpg?v=1788694926","url":"https:\/\/voomisupply.com\/products\/hertel-2386746-screw-machine-drill-bit-11-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
