Built to Series 860-GM specifications, it carries a multi-layer TiAlSiN and TiSiN coating that extends tool life and supports elevated cutting speeds. The bit measures 8.50 mm (0.3346 inches) in diameter with a 140-degree drill point angle engineered for self-centering entry and reduced thrust force. Overall length is 152.00 mm (5.98 inches), flute length is 106.00 mm (4.17 inches), and the straight cylindrical shank is 10.00 mm (0.39 inches) in diameter. This is a tool for machinists, CNC operators, and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 7781852 is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials — spanning ISO material groups P, M, K, N, S, and H. The 11xD flute-to-diameter ratio and coolant-through capability make it particularly suited for deeper hole applications where chip evacuation and thermal management are critical. It conforms to DIN 6535HA shank specifications and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiAlSiN and TiSiN coating for heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling up to 69.50 mm (2.74 inches)\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute; two-flute geometry balances chip flow and rigidity\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank conforms to DIN 6535HA for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eMaterial grade X1BM optimized for high-performance drilling across ISO P, M, K, N, S, and H material groups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or direct-use tooling for machining centers, CNC drilling stations, and manual drill presses accepting a 10.00 mm straight cylindrical shank conforming to DIN 6535HA.

Ensure the machine spindle and toolholder are fully powered down and locked before changing tooling. Verify toolholder bore and collet size match the 10.00 mm shank diameter before clamping. When using coolant-through capability, confirm the machine coolant circuit is properly connected and set to the tool manufacturer's recommended flow rate before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.50 mm (0.3346 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 152.00 mm (5.98 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 106.00 mm (4.17 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 69.50 mm (2.74 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.50 mm (0.059 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.39 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlSiN and TiSiN Multi-Layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: X1BM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 11xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 860-GM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6535HA\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, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Group Codes\u003c\/strong\u003e: P, M, K, N, S, H\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: 0.236 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.5 inches (L) x 0.59 inches (W) x 0.59 inches (H)\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7781852\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749148098866,"sku":"7781852","price":578.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96acd2aaa614114841d050ab35ad8005_43dd4e1a-7f69-47a8-a303-659f3819798f.jpg?v=1788902627","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7781852-carbide-jobber-drill-bit-8-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
