It features a 140-degree point angle ground to a standard point type, making it well suited for entry through harder materials without excessive thrust. A multilayer TiAlN coating reduces heat buildup at the cutting edge and extends tool life in demanding applications. The two-flute regular spiral design promotes chip evacuation, and the through-coolant capability allows direct delivery of cutting fluid to the tip. Overall length is 2.5984 inches (66.00 mm) with a flute length of 1.1024 inches (28.00 mm).\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for precision hole-making in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It is appropriate for CNC machining centers, production drilling, and manual drill press operations where consistent hole quality and tight diameter tolerance are required. The straight cylindrical shank diameter of 0.6875 inches fits standard collet chucks and drill holders. Maximum drilling depth is 0.9055 inches (23.00 mm). The 5xD flute-to-diameter ratio and tapered web configuration support stable cutting in short-to-medium depth holes across a wide range of workpiece materials.\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 workpiece materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating reduces friction and thermal load at the cutting edge\u003c\/li\u003e\n\u003cli\u003e140-degree point angle minimizes walking and reduces thrust force on entry\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design delivers cutting fluid directly to the drill tip for deep-hole thermal management\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 6537K specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification replacement or direct-use drill for CNC and manual machining applications requiring a wire gauge number 27 diameter drill in solid carbide with a straight cylindrical shank.

Ensure the machine spindle and collet or chuck are powered down and fully stopped before loading or removing the drill. Verify shank runout and chuck engagement before beginning a drilling cycle. Use manufacturer-recommended coolant flow rates when using the through-coolant feature to prevent thermal damage to the carbide substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6875 inches (6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9055 inches (23.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0235 inches (0.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 4149187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743880905010,"sku":"4149187","price":136.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fdfb47a6ae2c56ef90fe5dcca501217c.jpg?v=1788850713","url":"https:\/\/voomisupply.com\/products\/kennametal-4149187-jobber-drill-size-27-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
