Built from solid carbide and coated with TiAlN at the tip, this bit delivers exceptional wear resistance and heat dissipation at elevated spindle speeds. The 140-degree split point reduces thrust force and walking at entry, making it well suited for CNC machining centers, drill presses, and automated production environments. At 4.2126 inches overall length with a 1.6929-inch maximum drilling depth, the stub configuration provides rigidity and minimizes deflection in short-reach applications. Licensed machinists, CNC operators, and precision toolroom technicians are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThe 4150319 is used in production machining and job shop environments where stub-length rigidity is required over jobber-length reach. Its 1\/2-inch diameter and straight cylindrical shank accommodate standard drill chucks, collet holders, and hydraulic toolholders with a matching bore. The Series B041A-CPG designation covers a family of solid carbide stub drills built to DIN 6537K specification, making this an appropriate replacement for worn or damaged tooling within that series. Right-hand cutting direction suits conventional CNC and manual drilling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating reduces heat buildup and wear at the cutting edge\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle minimizes entry thrust and reduces workpiece walking\u003c\/li\u003e\n\u003cli\u003eStub-length body at 4.2126 inches overall provides superior rigidity versus jobber-length drills\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBuilt to DIN 6537K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement within the KENNAMETAL Series B041A-CPG stub-length solid carbide drill family, conforming to DIN 6537K specification.

Power down and lock out the machine spindle before changing tooling. Seat the shank fully in the chuck or collet and verify runout before resuming production. Avoid hand-grinding carbide tooling without proper diamond wheel equipment, as improper regrinding will alter the point geometry and void dimensional conformance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2126 inches (107.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3622 inches (60.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6929 inches (43.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches (45.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0860 inches (2.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B041A-CPG\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: 0.38 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: 4150319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753106112818,"sku":"4150319","price":206.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8a8936a461b789a0e8dc1ece1c4c2cc.jpg?v=1788932842","url":"https:\/\/voomisupply.com\/products\/kennametal-4150319-1-2-inch-stub-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
