It features a 140-degree split point geometry with X-thinned web for reduced thrust and cleaner entry, and is finished with OSG EgiAs multi-layer coating to extend tool life under heat and abrasion. The bit measures 8.70 mm (0.3425 inches) in diameter with a 128.00 mm (5.04 inches) overall length and a 70.00 mm (2.76 inches) flute length. Coolant-through capability supports high-speed production drilling where chip evacuation and thermal control are critical. Licensed machinists and tool-and-die professionals are the primary users of this drill.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for machining steel, cast iron, and hardened materials in both job shop and production environments. The straight cylindrical shank with a 10 mm shank diameter fits standard drill chucks and collet holders. The 5xD flute-to-diameter ratio makes it appropriate for moderate-depth holes in a jobber-length setup. It is well-matched to CNC machining centers, drill presses, and manual knee mills where rigid tool holding and through-spindle or external coolant delivery are available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs multi-layer proprietary coating reduces friction and extends tool life when drilling steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with X-thinned web minimizes thrust force and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and thermal management in deep or high-feed applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 5xD ratio balances chip evacuation and drill rigidity at jobber length\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 10 mm diameter provides broad compatibility with standard toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style jobber drill for use in steel, cast iron, and hardened material applications within the 8.00 mm to 9.00 mm drill diameter range (0.3000 to 0.3500 decimal inch range).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling handling and machine setup. Secure the straight shank fully in a collet, drill chuck, or hydraulic holder rated for the shank diameter before operation. Carbide is brittle  -  avoid side loads, interrupted cuts without proper feeds and speeds, and impact handling that can chip the cutting edges. Verify coolant delivery is active before engaging the workpiece when using the through-coolant feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.70 mm (0.3425 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EgiAs Multi-Layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 128.00 mm (5.04 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 70.00 mm (2.76 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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.25 inches (L) x 0.65 inches (W) x 0.55 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8702870\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740246802738,"sku":"8702870","price":354.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36adc2d2617bb4917925c3f830045324_cdbf3cce-8575-497b-8725-48753b02cc03.jpg?v=1788823735","url":"https:\/\/voomisupply.com\/products\/osg-8702870-solid-carbide-jobber-drill-8-70-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
