The drill measures 5.40 mm in diameter with a 140-degree self-centering point and a TiAlN coating that extends tool life under demanding conditions. Overall length is 3.2283 inches, with a 1.7323-inch flute length and a 6.00 mm straight-cylindrical shank conforming to DIN 6535HA. Internal coolant-through capability supports chip evacuation and heat control during deep-hole operations. This is a two-flute, right-hand cutting tool built from micrograin carbide stock for machinists and toolroom professionals working in production environments.\u003c\/p\u003e\u003cp\u003eThe R840 series drill is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium — ISO material groups P, M, K, N, and S. The 7xD flute-to-diameter ratio provides the reach needed for moderately deep holes without requiring a stub-length tool. The self-centering 140-degree point reduces the need for a center drill or spot drill in many setups, making it a practical choice for CNC machining centers and drill presses running through-coolant programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.40 mm diameter solid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e140-degree self-centering point reduces setup steps on CNC and manual equipment\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends cutting life in ferrous and exotic alloys\u003c\/li\u003e\n\u003cli\u003eInternal coolant-through design supports chip evacuation at 7xD drilling depths\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral geometry with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eDIN 6535HA shank specification ensures consistent toolholder fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in ISO material groups P (steel), M (stainless steel), K (cast iron), N (non-ferrous metals), and S (superalloys and titanium).

Seat the shank fully in a collet or drill chuck rated for the shank diameter before tightening. Connect through-coolant supply before initiating the drilling cycle to ensure proper chip flushing and thermal management. Verify runout with a dial indicator after clamping, as excessive runout accelerates wear and reduces hole-diameter accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5.40 mm (0.2126 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Self Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.2283 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.7323 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0354 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 Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6535HA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R840\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.41 inches L x 0.98 inches W x 0.98 inches H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5747378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51745743929650,"sku":"5747378","price":354.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68290da105e9dbdceef485698e350d4c_54f351d6-277b-4ed7-8394-fc6acd6b52e3.jpg?v=1788865025","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5747378-jobber-drill-5-40-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
