Screw machine length drills are shorter than jobber-length bits, which increases rigidity and reduces deflection when drilling in tight setups or production environments. The split point geometry engages the workpiece immediately without a center punch, and the web-thinned parallel web minimizes thrust force. This bit is suited for machinists, maintenance technicians, and fabricators drilling steel, cast iron, and similar ferrous materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in screw machine operations, drill presses, CNC machining centers, and hand-held power drills where a short, rigid bit is required. The straight-cylindrical shank accepts standard three-jaw drill chucks. The regular spiral flute and right-hand cutting direction make it compatible with conventional clockwise-rotating spindles. It is well matched to production drilling tasks in metal fabrication, maintenance repair, and light manufacturing applications where Letter C sizing is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter C size (0.2420 inches) with straight-cylindrical shank of equal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering engagement and reduced thrust\u003c\/li\u003e\n\u003cli\u003eTiN coating extends cutting edge life and reduces friction on ferrous materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers axial cutting force\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.5 inches OAL) provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade high-speed steel construction for demanding drilling cycles\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design  -  suitable for standard flood, mist, or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for any standard three-jaw drill chuck or collet system accepting a 0.2420-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this bit only with the machine fully powered down and the spindle at a complete stop. Secure the straight shank firmly in the drill chuck or collet to the full depth of the shank to prevent slippage under load. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when drilling ferrous metals. Inspect the cutting edges and TiN coating for wear before each use and replace the bit when the coating is fully worn through at the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2420 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2420 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 0.1 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: 66693417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739508212018,"sku":"66693417","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2cf77a4257726a50a188c35b16202cb7.jpg?v=1788815427","url":"https:\/\/voomisupply.com\/products\/hertel-66693417-drill-bit-letter-c-135-deg-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
