Built from heavy-duty cobalt steel and coated with TiAlN for extended tool life at elevated cutting temperatures, this bit handles tough ferrous and non-ferrous materials without rapid edge breakdown. The 135-degree split point geometry starts on contact without center-punching, reducing walking and improving positional accuracy. At 2-7\/16 inches overall length, the shortened body delivers added rigidity compared to jobber-length bits, making it well suited for CNC machines, drill presses, and screw machine work where runout and deflection must be minimized.\u003c\/p\u003e\u003cp\u003eThis bit is used in metal-cutting environments where heat and tool wear are primary concerns. The TiAlN coating performs well in dry or minimally lubricated cutting conditions, especially in stainless steel, alloy steel, cast iron, and high-temperature alloys. It is a standard choice for production machining shops, tool rooms, and maintenance environments requiring consistent, repeatable hole quality. The 0.2210 inch diameter corresponds to wire gauge size 2, making it a direct fit for applications specifying that size designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeavy-duty cobalt steel construction resists heat and abrasion in tough materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends cutting life and reduces friction at high surface speeds\u003c\/li\u003e\n\u003cli\u003e135-degree split point eliminates center-punch requirement and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces cutting resistance without sacrificing rigidity\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides extra stiffness and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for setups requiring wire gauge size 2 (0.2210 inch diameter) in any drill press, CNC machining center, or screw machine accepting a 0.2210 inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine fully powered down and the spindle at a complete stop. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet to the chuck manufacturer's torque specification. Inspect the cutting edges and TiAlN coating for chipping or wear before each use, as a damaged edge will compromise hole quality and increase the risk of bit breakage. Always follow applicable machine shop safety practices and applicable OSHA standards when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2210 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: TiAlN\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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 Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches\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: 66692302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739298922802,"sku":"66692302","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3f6f3ee06769f7bdc8afe55c443bf49.jpg?v=1788812837","url":"https:\/\/voomisupply.com\/products\/hertel-66692302-screw-machine-drill-bit-size-2-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
