It is designed for production holemaking in metal and general-purpose materials where extended tool life is required. The 135-degree split point reduces walking on entry and lowers thrust force compared to a conventional 118-degree point. The web-thinned, tapered web construction improves chip evacuation and cutting efficiency. At 4-5\/8 inches overall length with a 3-5\/16-inch flute, this is a standard jobber-series geometry sized for use in drill presses, CNC machining centers, and hand-held power tools. Installation is performed by machinists, tool-and-die techs, and maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for through-hole and blind-hole applications in ferrous and non-ferrous metals, plastics, and composite materials. The letter P size corresponds to a decimal diameter of 0.3230 inches, placing it in the 0.3000 to 0.3500 inch size range. It is well matched to production environments requiring consistent hole sizing for tapped holes, reamed bores, or clearance fits. The straight-cylindrical shank seats directly in standard drill chucks and collet systems without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter P size  -  0.3230 inch decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix clears chips efficiently on through and blind holes\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade high speed steel construction  -  NAS specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-series drill bit with a straight-cylindrical shank compatible with keyed and keyless drill chucks and collet tool holders accepting a 0.3230 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the chuck or collet before operation and confirm the bit runs true before engaging the workpiece. Disconnect power or engage the machine lockout before changing bits, in accordance with applicable OSHA lockout-tagout procedures. Use appropriate cutting fluid or coolant for the workpiece material to maximize coating life and maintain hole tolerance. Do not force the bit through hardened materials beyond the rated grade of the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3230 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular Helix)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 0.3000 to 0.3500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 66693896\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740483158322,"sku":"66693896","price":19.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd780cae5d9ba0b4518342ffbada7263.jpg?v=1788825307","url":"https:\/\/voomisupply.com\/products\/hertel-66693896-jobber-drill-bit-letter-p-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
