Built to DIN 6537L specification, it features a 140-degree point angle with web thinning for reduced thrust and cleaner entry, a TiAlN coating for heat resistance and extended tool life, and a regular spiral flute geometry optimized for chip evacuation. The drill measures 7.70 mm (0.3031 inches) in diameter with an overall length of 91.00 mm (3.5827 inches). Coolant-through capability makes it suitable for deep-hole and production drilling where heat management is critical. Material grade KC7315 positions this drill for consistent performance across a broad range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis drill is suited for machining steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both production and job-shop environments. The straight cylindrical shank, 8 mm (0.3150 inches) in diameter, fits standard drill chucks and collet systems. With a maximum drilling depth of 43.00 mm and a flute length of 53.00 mm (2.0866 inches), it handles typical jobber-length through-hole and blind-hole operations on CNC machining centers, lathes, and drill presses used in metal fabrication and precision machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in material grade KC7315 for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal barrier and extends cutting edge life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree split point with web thinning reduces thrust and improves self-centering at entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole drilling and high-feed applications\u003c\/li\u003e\n\u003cli\u003eDIN 6537L specification ensures dimensional consistency for interchangeable tooling setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production drill for machining steel, stainless steel, cast iron, aluminum, and non-ferrous workpieces where a 7.70 mm diameter hole is required.

Ensure the machine spindle and tool holder are clean and free of runout before seating the straight shank. Confirm coolant-through passages in the spindle are clear and pressurized before engaging coolant-through mode. Follow the machine manufacturer and OSHA guidelines for spindle speed, feed rate selection, and workholding before beginning any drilling operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.70 mm (0.3031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.5827 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.0866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC7315\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: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0981 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1992230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728750051634,"sku":"1992230","price":225.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/170ffe9219af665c19cf53aa5ba81ef6.jpg?v=1788695818","url":"https:\/\/voomisupply.com\/products\/kennametal-1992230-jobber-drill-7-70mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
