Its shortened overall length of 2.75 inches provides added rigidity compared to jobber-length bits, reducing deflection during entry and improving hole accuracy in CNC machining centers, drill presses, and manual operations. The 118-degree split-point geometry is a standard general-purpose angle suited to a wide range of workpiece materials. Manufactured from high-speed steel with a bright uncoated finish, this bit delivers consistent performance without the added cost of specialty coatings. Right-hand cutting direction is standard for conventional rotating spindles.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are commonly used in production machining, toolroom work, and maintenance applications where stub-length rigidity is preferred over extended reach. The 19\/64 inch diameter (0.2969 inch decimal equivalent) falls within the 0.2500 to 0.3000 inch size range and is a frequent choice for clearance holes, tap-drill preparation, and close-tolerance boring in light industrial and trade settings. Machinists, maintenance technicians, and metalworkers are the primary installers of this type of bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e19\/64 inch (0.2969 inch) diameter for precise, repeatable hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle suits general-purpose drilling across common materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.75 inches OAL) provides greater rigidity than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles moderate heat and cutting speeds\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows easy visual inspection of cutting edge condition\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for use with standard clockwise-rotating spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production-use screw machine length drill bit compatible with any standard drill chuck or collet accepting 19\/64 inch round shanks on drill presses, CNC machining centers, or hand drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the bit fully in the chuck or collet before applying spindle power, ensuring no shank runout. Always power down and lock out the machine before changing bits. Use appropriate cutting fluid for steel workpieces to extend edge life and manage heat buildup. Inspect the cutting edges for wear or chipping before each use and replace if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inches (0.2969 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5625 inches\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: 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\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2500 to 0.3000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 89321558\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749424464178,"sku":"89321558","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f98f0ef3b50e62f2fc2910fe8fccda46.jpg?v=1788905923","url":"https:\/\/voomisupply.com\/products\/hertel-89321558-screw-machine-drill-bit-19-64-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
