It measures 7.00 mm in diameter with an overall length of 91.00 mm (3.5827 inches) and features a 140-degree split-point geometry for accurate self-centering entry and reduced thrust. The multilayer TiAlN coating extends tool life by resisting heat buildup at elevated cutting speeds. With two regular spiral flutes and a flute-to-diameter ratio of 5xD, this drill moves chips efficiently while maintaining hole quality. Coolant-through capability supports deep-hole applications and helps manage heat in difficult materials. It conforms to DIN 6537K specification.\u003c\/p\u003e\u003cp\u003eThis drill is intended for machining steel, stainless steel, cast iron, aluminum, and other non-ferrous metals. It is suited to CNC machining centers, drill presses, and automated production cells where consistent hole tolerances are required. The straight cylindrical shank seats in standard collet chucks and hydraulic toolholders without modification. Maximum drilling depth is 43.00 mm (1.6929 inches), making it appropriate for through-holes and moderate-depth blind holes in structural and fabricated components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating for heat resistance and extended tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree point angle for accurate entry and reduced walking on flat or curved surfaces\u003c\/li\u003e\n\u003cli\u003eCoolant-through design to flush chips and control heat in deep-hole operations\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for consistent dimensional interchangeability\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0006 to 0.0000 inches for tight, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and drill presses with standard straight-shank collet chucks or hydraulic toolholders accepting an 8.00 mm shank diameter.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill. Seat the straight shank fully in the collet or chuck and torque the retention mechanism to the toolholder manufacturer's specification. Verify coolant-through passages are clear and coolant flow is active before starting the cut in deep-hole applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 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: 8.00 mm (0.2969 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: 43.00 mm (1.6929 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.18 mm (0.0464 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Multilayer 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: -0.0006 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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 4149240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744391987506,"sku":"4149240","price":207.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e38b84a7637dd1fc8fbbef160e6139b1.jpg?v=1788856125","url":"https:\/\/voomisupply.com\/products\/kennametal-4149240-jobber-drill-7mm-solid-carbide-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
