It measures 1\/4 inch (0.2500 inch) in diameter with a 140-degree split-point geometry that reduces walking and improves chip evacuation at entry. The TiAlN coating adds heat resistance and extends tool life in abrasive materials. At 3.5827 inches overall length with a 2.0866-inch flute, this drill delivers a balanced reach-to-rigidity ratio. Coolant-through capability keeps cutting edges cool and flushes chips during deep-hole operations. It is installed and run by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for use in ferrous and non-ferrous materials including steel, stainless steel, cast iron, and aluminum. The right-hand, regular spiral flute design handles a wide range of workpiece materials without requiring specialty tooling changes. Maximum drilling depth reaches 1.0000 inch (25.4 mm), making it appropriate for through-holes and moderate-depth blind holes in production runs. The shank diameter is 0.3750 inch, fitting standard drill chucks and collet holders common on CNC machining centers and manual drill presses.\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 materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends cutting tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces drill walk and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design flushes chips and controls heat at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute compatible with standard CNC and manual setups\u003c\/li\u003e\n  \u003cli\u003eDIN specification designation ensures dimensional conformance to recognized tooling standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-grade solid carbide jobber drill for use in standard drill chucks and collet holders accepting a 0.3750-inch shank diameter.

Verify that the machine spindle and chuck or collet are rated for the 0.3750-inch shank before securing the tool. Power down and lock out the machine before changing tooling. Coolant-through lines should be confirmed clear and at operating pressure before beginning the drilling cycle to prevent heat buildup and premature tool wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/4 inch (0.2500 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\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: 3.5827 inches (91.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0866 inches (53.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.0000 inch (43.00 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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 4149230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749522112818,"sku":"4149230","price":198.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9aa3ea89323861a55cb9d1ffe34d0ff5_e34e6534-03e5-4a14-bca4-1f55e4846de3.jpg?v=1788907158","url":"https:\/\/voomisupply.com\/products\/kennametal-4149230-solid-carbide-jobber-drill-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
