At 19\/64 inch (0.2969 inches) in diameter, this bit features a 135-degree split point for fast, accurate entry with minimal walking. The slow spiral flute geometry and web-thinned, parallel web configuration make it well-suited for chip evacuation in tough materials. At 2.75 inches overall length, the screw machine format provides added rigidity compared to jobber-length bits, reducing deflection in short-hole applications. Installed by machinists and metalworking trades, it is a drop-in-ready tool for CNC machines, drill presses, and manual lathes.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in difficult-to-machine metals including cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel. The solid carbide construction maintains cutting-edge integrity at elevated temperatures and feeds where high-speed steel bits would degrade. The right-hand cut and straight-cylindrical shank allow direct chuck mounting without adapters. It is a practical choice for production environments and job shop applications where consistent hole tolerance is required. Diameter tolerance is held to +0.0000 to -0.0005 inches for reliable fit in close-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for durability in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement on flat stock\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute with web-thinned parallel web improves chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.75 inches overall) provides rigidity and reduces deflection in short-hole drilling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel workpieces.

Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges for chipping before each use, as carbide is brittle and sensitive to side loading or interrupted cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inch (0.2969 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches (2-3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\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: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 74148958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740127232306,"sku":"74148958","price":54.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa9e5b2a3396973a9a5f5399389aae73.jpg?v=1788822623","url":"https:\/\/voomisupply.com\/products\/hertel-74148958-19-64-in-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
