At 11\/64 inches (0.1719 inches decimal) in diameter with a 118-degree split-point angle, it produces clean entry holes with minimal walking on flat stock. The shortened overall length of 2-1\/8 inches gives the bit added rigidity compared to jobber-length equivalents, reducing deflection when drilling in tight spaces or on drill press setups. The bright, uncoated finish suits standard drilling applications where lubrication is applied manually. This bit is a common consumable stocked by machinists, maintenance technicians, and HVAC or plumbing tradespeople for sheet metal and bracket work.\u003c\/p\u003e\u003cp\u003eThis drill bit fits standard three-jaw drill chucks and is well suited for bench drill presses, hand-held power drills, and drill press fixtures in shop or field environments. The screw machine length format is preferred in production machining and repetitive drilling tasks where a shorter, stiffer bit improves hole location accuracy. With a right-hand cutting direction and a 1-1\/16-inch flute length, it clears chips effectively in shallow-to-moderate depth holes across a wide range of base materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/64 inch diameter (0.1719 inches decimal) for precise fractional sizing\u003c\/li\u003e\n\u003cli\u003e118-degree point angle for general-purpose drilling in metal, wood, and plastic\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2-1\/8 inches OAL increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands heat buildup during continuous use\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with cutting fluids and manual lubrication\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 1-1\/16-inch flute length for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit suitable for use in any standard three-jaw drill chuck accepting 11\/64-inch round-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a properly sized drill chuck and tighten with a chuck key before operation. Secure the workpiece with a vise or clamp — never hold small stock by hand during drilling. Apply a cutting fluid or oil when drilling ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/64 inches (0.1719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\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\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: 89321590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752213348658,"sku":"89321590","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac9e74754df629912101e79b61cc7cae.jpg?v=1788926671","url":"https:\/\/voomisupply.com\/products\/hertel-89321590-screw-machine-drill-bit-11-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
