Stub drills feature a shorter flute length than jobber-length bits, which reduces deflection and improves rigidity when drilling in tight spaces or on drill presses and lathes. The HSS construction provides reliable hardness and heat resistance for everyday shop and field work. This bit is suited for machinists, pipefitters, electricians, and other tradespeople who need a compact, accurate drill for close-quarters applications.\u003c\/p\u003e\u003cp\u003eThe S400-021-I is appropriate for use in residential and commercial applications where a shorter, stiffer drill profile is preferred. Typical scenarios include drilling through sheet metal, structural steel, conduit fittings, or pipe flanges where a standard-length bit would flex or wander. The stub length makes it a practical choice for drill press work or for use in tight enclosures where bit overhang must be minimized.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/64 inch diameter for precise, consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction resists heat buildup during drilling\u003c\/li\u003e\n\u003cli\u003eStub flute length reduces deflection and improves hole accuracy\u003c\/li\u003e\n\u003cli\u003eCompact profile suited for restricted-access drilling locations\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 — available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit stub drill for standard 3-jaw drill chucks and keyed chuck systems accepting 21\/64 inch shank drill bits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eStub drills are installed and operated by machinists, pipefitters, electricians, and general tradespeople using standard drill presses, hand drills, or lathes. Always secure the workpiece and ensure the chuck is fully tightened before operation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 21\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Type\u003c\/strong\u003e: Stub Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S400-021-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233628389682,"sku":"S400-021-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623716.png?v=1780105089","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-s400-021-i-hss-stub-drill-21-64","provider":"Voomi Supply","version":"1.0","type":"link"}
