Built to DIN 6537K standards and coated with TiAlN for extended tool life, this bit delivers consistent performance in demanding production environments. It measures 7.80 mm in diameter with a 140-degree point angle optimized for accurate entry and reduced thrust. The overall length is 79.00 mm, making it well-suited for short-reach, rigid setups on CNC machines and drill presses. The KC7315 carbide grade and Dynapoint geometry make this a reliable choice for machinists and tool-and-die professionals running high-volume operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in ferrous metal applications, with primary workpiece materials listed as cast iron and steel. The screw machine length body provides greater rigidity compared to jobber-length bits, which is advantageous in tight-tolerance machining centers, turret lathes, and multi-spindle setups. The TiAlN coating supports higher cutting speeds and temperatures, reducing wear in production runs. It is suited for both manual machine shops and automated CNC drilling operations where consistent diameter tolerance and tool life are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in KC7315 grade for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree Dynapoint geometry reduces thrust and improves point accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web configuration for easier penetration in hard materials\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard straight-shank drill chucks and collet holders accepting an 8.00 mm shank diameter, suitable for CNC machining centers, turret lathes, and multi-spindle drilling setups processing cast iron and steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed by a qualified machinist or tooling technician familiar with carbide tooling handling and machine setup. Secure the straight shank in a properly sized collet or drill chuck before operation and verify runout before cutting. Carbide tooling is brittle and should never be subjected to impact loading or side forces beyond design parameters. Always follow machine manufacturer guidelines and applicable shop safety standards when setting feeds and speeds for carbide drill bits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.80 mm (0.3071 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (3.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 29.00 mm (1.1417 inches)\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 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Dynapoint High Performance\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 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B966A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0441 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: 1913486\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752859894066,"sku":"1913486","price":148.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10731b0c3477131438abde76f4e1028b.jpg?v=1788930706","url":"https:\/\/voomisupply.com\/products\/kennametal-1913486-screw-machine-drill-bit-7-80mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
