Built to DIN 6537K specification, it features a 140-degree point angle for aggressive penetration and reduced thrust in hard and abrasive materials. The TiAlN multilayer coating on the tip extends tool life in high-temperature cutting applications. At 89.00 mm overall length and 9.80 mm diameter, this right-hand, two-flute bit delivers consistent hole quality at a 3xD depth-to-diameter ratio. It is installed and operated by machinists, tool and die technicians, and production drilling professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for stub-length drilling operations in CNC machining centers, manual drill presses, and production screw machine setups. The straight cylindrical shank with a 10.00 mm shank diameter seats securely in standard drill chucks and collet systems. The tapered web configuration and regular spiral flute promote chip evacuation in steel, stainless, cast iron, and other ferrous and non-ferrous alloys. Coolant-through capability supports internal coolant delivery, making it well matched for through-spindle coolant machine tools where heat management is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating extends tool life under high cutting temperatures\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole thermal management\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003e3xD flute-to-diameter ratio provides a short, stiff geometry that minimizes deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification replacement or direct-use stub drill for CNC and production drilling applications requiring a 9.80 mm diameter, straight-shank, coolant-through solid carbide drill bit conforming to DIN 6537K.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and CNC operators in drill chucks or collet tool holders rated for the 10.00 mm straight shank diameter. Ensure the machine spindle and coolant system are fully powered down and depressurized before changing tooling. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout accelerates carbide tool wear. Follow machine tool manufacturer guidelines for spindle speed and feed rate when setting up for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.80 mm (0.3858 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.5039 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm (1.8504 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm (1.3780 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.67 mm (0.0658 inches)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer (TiN Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.015 to 0.000 mm (-0.0006 to 0.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\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: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.5 x 1.2 x 1.2 inches\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: 4151199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737068175666,"sku":"4151199","price":181.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_9a0f5193-e862-49a1-8bb6-ca5a0355662f.jpg?v=1788783841","url":"https:\/\/voomisupply.com\/products\/kennametal-4151199-screw-machine-drill-bit-9-80mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
