It measures 4.70 mm (0.185 inches) in diameter with a 135-degree split point geometry that reduces walking and lowers thrust requirements at entry. The drill carries a multi-layer TiAlCr\/TiSi proprietary coating engineered to extend tool life in abrasive and heat-generating cuts. Overall length is 98 mm (3.858 inches) with a 44 mm (1.732 inches) flute length, placing it in the 5xD flute-to-diameter class. A straight cylindrical shank at 5 mm (0.197 inches) diameter fits standard drill chucks and collet holders. This drill is part of the MDW-HGS series and is sold individually.\u003c\/p\u003e\n\u003cp\u003ePrimary workpiece materials for this drill are cast iron, stainless steel, carbon steel, and other ferrous alloys, covering ISO material codes K, M, P, and S. The 135-degree point and TiAlCr\/TiSi coating combination is well-suited for production environments where tool life and hole quality in tough materials are priorities. The coolant-through design supports internal coolant delivery, making it appropriate for CNC machining centers, drill presses, and automated lines where through-spindle coolant is available. Machinists, tool-and-die workers, and maintenance technicians working on steel fabrication or precision component drilling will find this drill applicable to those tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous metals\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiAlCr\/TiSi coating for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and axial thrust\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with internal coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration for chip clearance and rigidity balance\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance for consistent hole sizing and fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 5 mm straight cylindrical shank. Suitable for CNC machining centers and drill presses equipped with through-spindle coolant.

Ensure the shank is clean and seated fully in the collet or chuck before tightening to the chuck manufacturer's specified torque. When using the coolant-through feature, verify coolant pressure and flow rate are within the machine spindle's rated range before running. Discard the drill if chipping, excessive wear, or dimensional deviation in produced holes is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.70 mm (0.185 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multi-layer TiAlCr\/TiSi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 98 mm (3.858 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44 mm (1.732 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5 mm (0.197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 52 mm (2.047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.97 mm (0.038 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel (ISO K, M, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5V00159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730481054002,"sku":"5V00159","price":170.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa4dfcb25fd2ec4c15ca451a3321b008.jpg?v=1788718216","url":"https:\/\/voomisupply.com\/products\/sumitomo-5v00159-solid-carbide-jobber-drill-4-70mm-135deg","provider":"Voomi Supply","version":"1.0","type":"link"}
