Built from high speed steel with a black oxide coating, this bit runs at standard drilling speeds and resists wear and minor corrosion better than uncoated HSS. The 118-degree standard point angle makes it well suited for drilling into flat or pre-punched stock without requiring a pilot hole on most materials. With an overall length of 4.125 inches and a two-flute spiral design, the CD40308 delivers efficient chip evacuation on through-hole and blind-hole applications.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. The 0.2660-inch diameter corresponds to the Letter H size designation, placing it in the 0.2500 to 0.3000-inch range. It is a practical choice for HVAC, plumbing, electrical, and general mechanical trades where metal drilling is part of daily service work. The straight cylindrical shank fits standard drill chucks without adapters, and the right-hand cutting direction is compatible with all standard drilling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter H diameter: 0.2660 inches, within the 0.2500 to 0.3000-inch size range\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with black oxide coating for wear and corrosion resistance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 2.875 inches; flute length of 2.875 inches\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with zero flats for universal chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use jobber drill bit for standard three-jaw drill chucks accepting a 0.2660-inch straight cylindrical shank.

Secure the shank fully in the chuck before operation and verify the chuck is tightened to prevent slippage. Always wear appropriate eye protection and follow applicable OSHA standards when drilling metal. Coolant-through is not supported on this bit; use a suitable cutting fluid applied externally when drilling hard alloys or stainless steel to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CD40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD40308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51737261867314,"sku":"CD40308","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b4ce38d79a58993834a2ea78b6eaf1f.jpg?v=1788786324","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd40308-jobber-drill-bit-letter-h-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
