It measures 4.50 mm in diameter with a 140-degree point angle and features an AlTiN (Aluminum Titanium Nitride) coating for extended tool life in demanding materials. The overall length is 74.00 mm, with a 36.00 mm flute length and a 6 mm straight cylindrical shank. Coolant-through capability supports high-speed drilling operations where heat management is critical. Right-hand cutting with a regular spiral flute provides efficient chip evacuation and consistent hole quality in production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in steel, stainless steel, and high-temperature alloys, making it well suited for aerospace, automotive, and precision machining applications. The web-thinned, tapered web construction reduces entry thrust and improves centering accuracy. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 29.00 mm, it is appropriate for through-hole and blind-hole work on CNC machining centers and drill presses. It conforms to DIN 6537K specification, a common standard for carbide jobber drills used by professional machinists and tool-room technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on hard materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed, deep-hole drilling with effective heat and chip removal\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers entry force and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, and high-temperature alloys per manufacturer specification.

Secure the shank fully in a collet or drill chuck rated for the intended cutting speeds before operation. Verify coolant-through supply pressure and flow are correctly configured before running through-coolant cycles. Do not use this bit in hand-held drill applications; it is intended for rigid machine tool setups only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.50 mm (0.1772 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\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (2.9134 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2656 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 29.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.90 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: 0.004 to 0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, High-Temp Alloy\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 3640746\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727945302322,"sku":"3640746","price":289.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9aa3ea89323861a55cb9d1ffe34d0ff5.jpg?v=1788684858","url":"https:\/\/voomisupply.com\/products\/kennametal-3640746-solid-carbide-jobber-drill-4-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
