Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended wear resistance and reduced friction during repeated drilling cycles. The bit measures 2.25 inches overall length with a 1.1875-inch flute length, a 0.1890-inch decimal diameter corresponding to wire size 12, and a 135-degree split point that reduces walking and lowers thrust at entry. Screw machine length geometry keeps the tool short and stiff, making it well-suited for production environments and CNC or turret setups where overhang and deflection matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in machine shop, production drilling, and general metalworking applications where a stub-length tool improves rigidity over jobber-length alternatives. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. Its web-thinned, split point design is particularly useful when drilling steel, aluminum, and other metals in repetitive or automated cycles. Licensed machinists, tool and die technicians, and production floor operators are the typical end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 12 diameter at 0.1890 inches for precise decimal sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and eliminates center punching on most metals\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and lowers cutting temperatures\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.25 inches overall for maximum rigidity in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for wire size 12 screw machine length drill bits used in standard drill chucks, collet holders, and turret tooling that accept a 0.1890-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with rotating tool safety practices. Secure the shank fully in the chuck or collet before operation and verify runout before beginning a production run. Power down and de-energize the machine spindle before changing or inspecting tooling. Follow the machine manufacturer and applicable OSHA standards for RPM, feed rate, and coolant application when using coated HSS tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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 Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 2387306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744817185074,"sku":"2387306","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b14294111cdde4efaceac3d2bc2adf55.jpg?v=1788860890","url":"https:\/\/voomisupply.com\/products\/hertel-2387306-drill-bit-size-12-hss-tin-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
