The system supports a diameter range of 10–33 mm and hole depths from 3×D to 12×D, with hole tolerances of H9–H10 for process reliability. An internal coolant supply enhances chip control and stability, while optimized chip evacuation keeps the drilling zone clear. Tailor-made options for both the drill body and the exchangeable tip are available, enabling customization to match specific processes. The CoroDrill 870 family emphasizes long, predictable wear life and high productivity, with geometry designed for secure chip control, robust tool stability, and strong penetration in conventional drilling, cross holes, angled surfaces, pocket and step-drilling workpieces. The TM870.1-568929 variant represents Sandvik’s exchangeable-tip approach, balancing a rigid body design with a compatible replaceable drill tip to reduce downtime and tooling costs while maintaining drilling accuracy across a range of workpiece materials and hole sizes.\u003c\/p\u003e\u003c\/div\u003e","brand":"SANDVIK","offers":[{"title":"New","offer_id":46284076712170,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-022.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sandvik-coromant-tm870-1-568929-exchangeable-tip-drill","provider":"GTG Hardware","version":"1.0","type":"link"}
