It accepts SMDT-style insert tips and is built around the SMD series platform, pairing a steel body with a 1-inch Weldon flat shank for positive, non-slip drive in compatible toolholders. The drill covers a diameter range of 21.51 to 22.80 mm (0.8469 to 0.8976 inches) and reaches a maximum drill depth of 4.882 inches at a 5xD depth-to-diameter ratio. Through-spindle coolant delivery channels coolant directly to the cutting zone, extending insert life and improving chip evacuation in deep-hole operations. Machinists and toolroom technicians working in production or job-shop environments will find this body well suited to high-feed drilling cycles.\u003c\/p\u003e\n\u003cp\u003eThe 5L00W0Y is intended for use in CNC machining centers and drill presses equipped with Weldon flat shank toolholders using the SMDH holder style. The 5xD depth-to-diameter ratio makes it a practical choice for moderate-depth bores in steel, cast iron, and similar ferrous workpiece materials. The replaceable-tip design reduces tooling cost per hole by allowing insert swaps without removing or re-indicating the body. Applications include through-hole and blind-hole drilling in general manufacturing, automotive, and heavy equipment component production.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiameter range: 21.51 to 22.80 mm (0.8469 to 0.8976 inches) using interchangeable SMDT insert tips\u003c\/li\u003e\n  \u003cli\u003e5xD drill depth-to-diameter ratio with a maximum drilling depth of 4.882 inches\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant construction channels fluid directly to the cutting edge for improved chip flushing and thermal control\u003c\/li\u003e\n  \u003cli\u003e1-inch Weldon flat shank (2.25 inches shank length) provides positive drive and resists rotation in SMDH-style holders\u003c\/li\u003e\n  \u003cli\u003eOverall length of 7.874 inches with a flute and body length of 5.624 inches for reach into workpiece features\u003c\/li\u003e\n  \u003cli\u003eSteel body construction balances rigidity and weight for stable performance in production drilling cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SMDT-style replaceable insert tips and SMDH-series toolholders as part of the SUMITOMO SMD drill platform.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body from the toolholder. Seat the Weldon flat shank fully into the holder and tighten the drive screw against the flat per the toolholder manufacturer's torque guidance. Verify through-coolant supply lines are connected and unobstructed before initiating a drilling cycle, and confirm insert tip seating and clamping prior to first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 21.51 mm (0.8469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 22.80 mm (0.8976 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 4.882 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.624 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5.624 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: SMDT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SMDH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SMD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5L00W0Y\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51737841369394,"sku":"5L00W0Y","price":518.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/171e41d3c0b80d95dba82bf6e1545571.jpg?v=1788794151","url":"https:\/\/voomisupply.com\/products\/sumitomo-5l00w0y-replaceable-tip-drill-21-51-22-8mm-weldon","provider":"Voomi Supply","version":"1.0","type":"link"}
