Screw machine length bits are shorter than jobber-length bits, which gives them added rigidity and reduces deflection when drilling in metalworking applications. The split point geometry engages the workpiece immediately without walking, and the TiN coating extends cutting edge life by reducing friction and heat buildup. The web-thinned, parallel-web construction supports chip evacuation through the spiral flute. Right-hand cutting direction. Intended for use by machinists, maintenance technicians, and metalworking trades.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling and maintenance drilling in steel, stainless steel, cast iron, and other ferrous and non-ferrous metals. The heavy-duty cobalt grade makes it appropriate for harder workpiece materials where high-speed steel tooling wears prematurely. The short screw machine length is well matched to drill press, CNC, and turret lathe setups where rigidity and chatter control are priorities. The straight cylindrical shank fits standard 3-jaw chucks without a reducer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction rated for heavy-duty drilling in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction, extends cutting edge life, and improves heat resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts without a center punch and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web promotes chip flow and lowers cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides greater rigidity than jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for any application requiring a Letter P (0.3230 inch) diameter hole in metalworking operations.

Use cutting fluid or coolant appropriate to the workpiece material to manage heat and extend tool life, especially when drilling stainless steel or hardened alloys. Inspect the cutting edge before each use and remove the bit from service if chipping or dullness is observed. Follow machine manufacturer guidelines and applicable shop safety standards when operating drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3230 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\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\u003eShank Diameter\u003c\/strong\u003e: 0.3230 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches (2-15\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6875 inches (1-11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\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: 0.1 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: 66691650\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740922249522,"sku":"66691650","price":18.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/373e784f2050df138f4a094564eca79a.jpg?v=1788828349","url":"https:\/\/voomisupply.com\/products\/hertel-66691650-cobalt-drill-bit-letter-p-0-3230-in","provider":"Voomi Supply","version":"1.0","type":"link"}
