Built from powdered metal and coated with FIREX for extended tool life, this bit features a 130-degree point angle with cone relief geometry and a parabolic flute profile that promotes fast chip evacuation. The straight-cylindrical shank measures 1.19 mm in diameter and fits standard drill chucks without adapters. At 30 mm (1.1811 inches) overall length, the compact stub format provides added rigidity and reduces deflection in short-depth applications. It meets DIN 1897 standards and carries a diameter tolerance of h8.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in cast iron and steel workpieces. The stub length and parabolic flute design make it a practical choice for CNC machining centers, screw machines, and bench drill press work where hole depth is limited to roughly 3xD. Maximum drilling depth is 0.245 inches (6.22 mm), making it appropriate for shallow through-holes and spot-facing operations. It is sized for applications requiring a 3\/64 inch (0.0469 inch decimal) bore diameter with right-hand cutting direction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction with FIREX coating for improved wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with cone relief for accurate entry on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eParabolic fast-spiral flutes for efficient chip removal in deep-for-diameter cuts\u003c\/li\u003e\n  \u003cli\u003eStub length format reduces deflection and increases rigidity versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers thrust requirements at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 standard with h8 diameter tolerance for consistent sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or production-use drill bit for applications requiring a 3\/64 inch straight-cylindrical shank stub drill in cast iron or steel, conforming to DIN 1897 Series 515 geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and toolroom technicians. Secure the straight-cylindrical shank fully into the drill chuck or collet before operation and verify concentricity before running at speed. Power down and lock out the machine before changing or seating the bit. Do not exceed the recommended maximum drilling depth of 0.245 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/64 inch (0.0469 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30 mm (1.1811 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8 mm (0.315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 6.22 mm (0.245 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22 mm (0.8661 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005150011900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754555703602,"sku":"9005150011900","price":25.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbe102cf79a0c87a2f3cab70a6ecfed3_fa776a29-300f-4a29-b7f5-f75f369d9632.jpg?v=1788946574","url":"https:\/\/voomisupply.com\/products\/guhring-9005150011900-stub-drill-bit-3-64-in-firex","provider":"Voomi Supply","version":"1.0","type":"link"}
