Built with a 135-degree split point geometry, this bit starts on contact without a center punch and reduces the tendency to walk on hard or slick surfaces. The Dyno Black Gold finish provides a surface treatment intended to extend tool life under repeated use. This drill bit is manufactured in the USA and suited for use by machinists, millwrights, pipefitters, and general trade professionals who require consistent, accurate drilling performance.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is appropriate for use in hand drills, drill presses, and CNC drilling applications across residential, commercial, and light industrial settings. The 21\/64-inch diameter makes it a common choice for bolt clearance holes, pilot holes, and pre-drill work on structural and mechanical assemblies. It is a direct fit for standard three-jaw drill chucks accepting fractional shank sizes in this range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point tip reduces walking and improves starting accuracy on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel (HSS) construction provides durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDyno Black Gold surface treatment for enhanced wear resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003e21\/64-inch fractional diameter suits common bolt clearance and pilot hole applications\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fractional drill bit compatible with standard three-jaw drill chucks accepting 21\/64-inch shank sizes in hand drills, drill presses, and compatible CNC drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance technicians, and trade professionals using standard drill chucks. Secure the bit firmly in the chuck before operation and verify chuck key removal prior to starting the drill. Use appropriate cutting fluid when drilling ferrous metals to reduce heat buildup and prolong bit life. Follow all applicable shop safety standards and wear eye protection during drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Dyno Black Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D250-021-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233783677234,"sku":"D250-021-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622357.png?v=1780108777","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-d250-021-d-hss-drill-bit-21-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
