Sized at Letter P (0.3230 inches decimal equivalent), this bit is ground from solid carbide and features a 135-degree split-point geometry that reduces walking and minimizes thrust force on entry. With an overall length of 2-15\/16 inches and a flute length of 1-11\/16 inches, the stub-length profile delivers the rigidity needed when drilling tough alloys. The two-flute slow spiral configuration promotes controlled chip evacuation in gummy or stringy materials. The bright uncoated finish maintains tight dimensional tolerances directly off the grind.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for use in machining operations where workpiece materials include cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel. It is well suited for CNC machining centers, manual mills, and drill presses where short, rigid tooling reduces chatter and deflection. The straight cylindrical shank fits standard Jacobs-style chucks and collet systems. Machinists, toolroom operators, and maintenance technicians working in metalworking and fabrication environments are the primary users of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides superior hardness and wear resistance compared to high-speed steel in abrasive and hard workpiece materials\u003c\/li\u003e\n\u003cli\u003e135-degree split-point reduces centering force and improves hole entry accuracy without a pilot dimple\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry promotes chip control in long-chipping materials such as stainless steel and nickel alloys\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length profile maximizes rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains precise diameter tolerance at 0.3230 inches across the full drill bit size range of 0.3000 to 0.3500 inches\u003c\/li\u003e\n\u003cli\u003eNo coolant-through passages — suitable for conventional flood coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new installation solid carbide screw machine drill bit for use in any standard straight-shank chuck or collet system accepting a cylindrical shank at the Letter P diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians using a standard Jacobs chuck, ER collet, or equivalent workholding system. Ensure the spindle is fully stopped and power is locked out before changing tooling. Verify chuck or collet bore is clean and free of chips before seating the shank to prevent runout. Solid carbide tooling is brittle — avoid side loads and interrupted cuts unless the setup is confirmed rigid.\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3000 to 0.3500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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 Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Nickel Alloy, Stainless Steel, Titanium Alloy, Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 16704447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750577373490,"sku":"16704447","price":78.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaccf33b09890dfd3dab5d77e085878b.jpg?v=1788916920","url":"https:\/\/voomisupply.com\/products\/hertel-16704447-drill-bit-letter-p-solid-carbide-135-pt","provider":"Voomi Supply","version":"1.0","type":"link"}
