Sized at Letter A (0.2340 inches decimal equivalent), it features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The bit is manufactured from high speed steel with a titanium nitride (TiN) coating that extends tool life and reduces friction during cutting. With an overall length of 3.875 inches and a flute length of 2.625 inches, it fits standard drill chucks and magnetic drill presses used in fabrication, maintenance, and industrial service work.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling and field repair applications where a right-hand, spiral-flute jobber bit is the standard choice. The straight-cylindrical shank at 0.2340 inches diameter seats securely in keyed or keyless chucks. The tapered web and web-thinned geometry reduce thrust load, making it practical for hand drills and drill presses alike. It is a heavy-duty grade bit conforming to NAS specification, appropriate for machinists, pipefitters, ironworkers, and general maintenance mechanics working in light to medium-duty drilling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter A size  -  0.2340 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eTiN coating extends cutting life and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles intermittent and continuous drilling cycles\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web geometry for reduced feed force\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular spiral type for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any keyed or keyless chuck accepting a 0.2340-inch straight-cylindrical shank, including benchtop drill presses, hand drills, and right-angle drills commonly used in fabrication and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with cutting tool selection and drill press or hand drill operation. Secure the shank fully in the chuck before drilling and verify spindle speed is appropriate for the workpiece material. Never exceed the rated speed for the bit diameter or material being drilled. Disconnect power to any drill press or tool before changing bits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: Letter A (0.2340 inches)\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\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 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: 0.2340 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS\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: 0.12 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: 66693755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739332870450,"sku":"66693755","price":15.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94b306c86dfc6e1fe05102a34642b4b2.jpg?v=1788813252","url":"https:\/\/voomisupply.com\/products\/hertel-66693755-jobber-drill-bit-letter-a-tin-hss-135","provider":"Voomi Supply","version":"1.0","type":"link"}
