Built with a 135-degree split point, it self-centers on contact to reduce walking and improve starting accuracy without a center punch. The black and gold surface finish is typical of Dyno BG-series bits, providing added surface hardness and heat resistance. This bit is suited for use in hand drills, drill presses, and CNC drilling operations across light fabrication and trade service applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is appropriate for residential and commercial trade work where accurate, clean-entry holes are required in ferrous and non-ferrous materials. Electricians, plumbers, HVAC technicians, and general contractors reach for HSS bits like this when drilling through sheet metal, steel pipe, brackets, and structural framing. The 21\/64 inch diameter fills a common need between standard fractional sizes, making it useful for bolt clearance holes and conduit knockout work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21\/64 inch diameter HSS construction for durability across a wide range of materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces drill walk on smooth or curved surfaces\u003c\/li\u003e\n  \u003cli\u003eDyno BG black and gold finish adds surface hardness and extends tool life under heat\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard drill chucks on hand drills, drill presses, and CNC equipment\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit for flexible purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose HSS drill bit suitable for use with standard 3-jaw drill chucks across hand drills, benchtop drill presses, and light-duty CNC drilling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the bit firmly in the chuck before operation and verify the drill is set to an appropriate speed for the material being drilled — harder materials require lower RPM. Wear appropriate eye protection and secure the workpiece to prevent spinning. Avoid applying excessive lateral force, which can snap smaller-diameter bits. Lubricate the cutting edge when drilling ferrous metals to reduce heat buildup and extend bit life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21\/64 inch\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: Black and Gold (Dyno BG)\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-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233612988722,"sku":"D250-021-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622177.png?v=1780104628","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-d250-021-i-hss-drill-bit-21-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
