Sized at Letter P (0.3230 inches decimal), this bit features a 135-degree split point that reduces walking on entry and lowers the thrust needed to start a hole. The titanium nitride (TiN) coating increases surface hardness and extends tool life in ferrous and non-ferrous materials. With an overall length of 2-15\/16 inches and a flute length of 1-11\/16 inches, it fits standard drill chucks and machine spindles. Intended for machinists, tool-room technicians, and maintenance trades working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are used where stub-length rigidity is preferred over jobber-length reach. The shortened body reduces deflection in drilling fixtures, CNC machining centers, drill presses, and hand-held power tools used in tight or confined setups. This bit is suited for repetitive hole production in mild steel, aluminum, cast iron, and similar materials. The right-hand spiral flute and web-thinned, parallel-web construction promote efficient chip evacuation in through-hole and blind-hole drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter P size  -  0.3230 inches decimal diameter with matching straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends cutting life over uncoated HSS\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\u003eHeavy-duty drill bit grade construction for production and repetitive drilling cycles\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement  -  compatible with standard external flood or mist coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for standard 3-jaw drill chucks and machine spindles accepting a 0.3230-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the chuck is secure before inserting or removing the bit. Verify that workpiece fixturing is rigid and that the selected spindle speed and feed rate are appropriate for the material being drilled. Eye protection and appropriate PPE must be worn during all drilling operations per applicable shop safety standards.\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: 2-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3000 to 0.3500 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: 66693532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741298622770,"sku":"66693532","price":18.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6cd74026447815f3b83e95aeb4d9bdca.jpg?v=1788830624","url":"https:\/\/voomisupply.com\/products\/hertel-66693532-screw-machine-drill-bit-letter-p-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
