Built from solid carbide and coated with a multilayer TiAlN finish at the tip, it delivers high hardness and heat resistance at the cutting edge. The 9.00 mm diameter bit features a 140-degree point angle, a tapered web configuration, and a right-hand spiral flute for efficient chip evacuation. At 89.00 mm overall length with a 47.00 mm flute length and a 10.00 mm straight-cylindrical shank, this bit is sized for rigid, close-clearance setups. Coolant-through capability supports high-feed drilling in ferrous and non-ferrous metals. It is rated to a maximum drilling depth of 35.00 mm (3xD flute-to-diameter ratio).\u003c\/p\u003e\u003cp\u003eThe 4151188 is suited for CNC machining centers, drill presses, and screw machine operations where short, stiff tooling is required to minimize deflection and maintain hole-location accuracy. Typical applications include production drilling in steel, cast iron, stainless steel, and similar materials where controlled chip load and thermal management are critical. The stub-length design reduces overhang, making it a preferred choice for high-volume production runs and tight-tolerance work. Machinists and tool-and-die professionals are the primary installers of this bit.\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\u003eMultilayer TiAlN coating at the tip for elevated-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels cutting fluid directly to the cutting edge for heat control and chip flushing\u003c\/li\u003e\n\u003cli\u003eTapered web and regular spiral flute geometry promote consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard ER collet chucks and drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub-length drill bit for use in standard straight-shank toolholders, collet chucks, and drill press spindles accepting a 10.00 mm shank diameter.

Secure the shank firmly in a properly sized collet or drill chuck to the tool manufacturer recommended clamping depth before applying any load. Verify coolant-through connections are clear and delivering adequate flow before initiating a drilling cycle. Do not exceed the maximum drilling depth of 35.00 mm per pass without a peck-drilling cycle to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.00 mm (0.3543 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\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm (1.3780 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\u003eDrill Point Length\u003c\/strong\u003e: 1.53 mm (0.0603 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\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer (TiN at Tip)\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.00 inches (L) x 1.3 inches (W) x 1.3 inches (H)\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: 4151188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739787297074,"sku":"4151188","price":180.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b699ab2e4e0a682f49dba7f06ca468c9.jpg?v=1788818869","url":"https:\/\/voomisupply.com\/products\/kennametal-4151188-solid-carbide-drill-bit-9-00-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
