It features a 21\/32 inch (0.6563 inch) diameter with a 140-degree point angle and a multilayer TiAlN coating that extends tool life by reducing heat buildup and wear at the cutting edge. The overall length is 5.63 inches (143 mm) with a flute length of 3.66 inches (93 mm). Coolant-through capability supports chip evacuation and thermal management during deep-hole drilling cycles. This drill is installed and operated by machinists and tool-and-die professionals in CNC and manual drilling applications.\u003c\/p\u003e\n\u003cp\u003eThe 4149371 is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both production-floor and job-shop settings. Its 5xD flute-to-diameter ratio and regular spiral flute geometry make it a practical choice for through-hole and blind-hole operations where consistent hole quality and dimensional accuracy are required. The straight cylindrical shank seats directly in standard drill chucks and collet holders without adapters. DIN 6537K specification compliance supports use in applications where tooling standardization is required.\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 and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces thermal load and extends cutting life compared to uncoated carbide\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle minimizes walking and reduces thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the cutting zone for deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification compliance for standardized tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style jobber drill compatible with primary workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.

Verify that the machine spindle and workholding are rated for the cutting forces associated with carbide tooling in hard materials before use. Confirm coolant-through passages are clear and coolant supply is active before beginning deep-hole drilling cycles. Do not use this drill to ream or side-load; it is designed strictly for axial drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/32 inch (0.6563 inch)\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: 5.63 inches (143 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.66 inches (93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1406 inch (18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.89 inches (48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.80 inches (71 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.114 inch (2.89 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\u003eSpiral Type\u003c\/strong\u003e: Regular\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\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\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: 4149371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741158506802,"sku":"4149371","price":645.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c80fa7d0de22b989bcc670c4cbb23cd.jpg?v=1788829704","url":"https:\/\/voomisupply.com\/products\/kennametal-4149371-solid-carbide-jobber-drill-21-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
