Built from cobalt with a titanium nitride (TiN) coating, this bit handles demanding applications where standard high-speed steel fails. The 135-degree split point geometry reduces walking and requires less feed pressure than a conventional 118-degree point. At 1.75 inches overall length, the stub-style body provides added rigidity compared to jobber-length equivalents, making it well-suited for drilling in tight clearances or on drill presses where chatter is a concern. This is a right-hand, spiral-flute bit with a straight-cylindrical shank and a web-thinned parallel web for improved chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThe 66692203 is designed for production machining, toolroom work, and heavy-duty maintenance drilling. Wire gauge size 44 translates to 0.0860 inches decimal, a common dimension for tapping pilots, precision clearance holes, and light-gauge sheet metal work. Its heavy-duty cobalt grade and TiN coating make it appropriate for ferrous metals, stainless steel, cast iron, and other abrasive materials that would wear out standard drill bits quickly. Machinists, tool and die technicians, and industrial maintenance mechanics will find this bit fits standard drill chucks and CNC toolholders that accept straight-cylindrical shanks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with TiN coating for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1.75 inches OAL provides rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets accepting 0.0860-inch shanks\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute for use with standard drill presses, CNC machines, and handheld drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for screw machine length drill bits in wire gauge size 44 with a 0.0860-inch straight-cylindrical shank, compatible with any standard drill chuck or collet accepting that shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a drill press, CNC machining center, or handheld drill with a chuck rated for the 0.0860-inch shank diameter. Secure the shank fully in the chuck and verify runout before drilling, as small-diameter bits are sensitive to misalignment. Use appropriate cutting fluid for ferrous and stainless applications to protect the coating and extend tool life. No coolant-through capability is present on this bit, so external fluid application is required for best results in production environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0860 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\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\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: 0.0860 inches\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\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: 0.1 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: 66692203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740133589298,"sku":"66692203","price":40.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58138f2b7e08b8e3e424ce493b3891b7.jpg?v=1788822697","url":"https:\/\/voomisupply.com\/products\/hertel-66692203-drill-bit-size-44-cobalt-tin-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
