Built to Series B977 specifications, it features a 140-degree split-point geometry and a TiAlN (titanium aluminum nitride) coating that extends tool life at elevated cutting temperatures. The straight-cylindrical shank measures 6 mm in diameter, and the overall length is 74 mm (2.9134 inches). Internal coolant-through capability supports high-speed drilling in ferrous and non-ferrous materials where chip evacuation and heat management are critical.\u003c\/p\u003e\u003cp\u003eThis drill is suited for CNC machining centers, drill presses, and automated production equipment in metalworking, aerospace, and precision fabrication shops. The right-hand spiral flute configuration and 5xD flute-to-diameter ratio make it a practical choice for through-hole and blind-hole applications in steel, stainless steel, cast iron, and similar hard materials. A maximum drilling depth of 29 mm keeps it well within jobber-length working parameters for most standard machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.09 mm (0.1719 inch) diameter solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eTiAlN coating increases surface hardness and heat resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels fluid directly to the cutting edge for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eTwo-flute right-hand spiral geometry promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003e6 mm straight-cylindrical shank compatible with standard collet and drill chuck toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-series replacement and standard production drill within the KENNAMETAL B977 series, fitting applications requiring a 4.09 mm drill in the 0.1500 to 0.2000 inch (4.00 to 5.00 mm) diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the shank fully in a collet, hydraulic chuck, or precision drill chuck rated for the shank diameter before operation. Verify spindle runout is within acceptable limits before cutting to avoid premature carbide failure. Do not use in handheld drill applications — solid carbide drills require rigid machine setups to prevent breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.09 mm (0.1719 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm (2.9134 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B977\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 0.7 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: 4150652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754935288114,"sku":"4150652","price":120.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0badca568ffbb1898d59202e58ae8ad_cac99bc0-c258-479b-8c73-879452ab2938.jpg?v=1788949939","url":"https:\/\/voomisupply.com\/products\/kennametal-4150652-carbide-jobber-drill-bit-4-09-mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
