Built from powdered metal and coated for extended wear resistance, it features a parabolic flute geometry with a fast spiral that improves chip evacuation and reduces heat buildup in the cut zone. The 130-degree point angle and cone relief point type make it well-suited for initiating cuts on curved or angled surfaces without a center punch. At 2.4409 inches overall length and 0.191 inches diameter, this bit is sized for short-reach applications where rigidity and accuracy matter. Machinists, tool and die shops, and maintenance mechanics working with cast iron and steel will find this a reliable production drilling tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in ferrous metal applications, specifically cast iron and steel, in both production and job-shop environments. The stub-length body reduces deflection, making it appropriate for drill press, CNC, and turret lathe applications where a compact cutting tool is required. The straight-cylindrical shank provides broad compatibility with standard drill chucks and collet systems. The web-thinned geometry reduces entry force, which is particularly useful when drilling thicker stock or when running higher feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.191 inches diameter with h8 tolerance for close-fit precision holes\u003c\/li\u003e\n  \u003cli\u003eParabolic fast-spiral flute promotes efficient chip removal in deep-hole and interrupted cuts\u003c\/li\u003e\n  \u003cli\u003e130-degree cone relief point reduces walking and improves self-centering on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction with coating provides enhanced hardness and abrasion resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers thrust force requirements and extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 standard, Series 515, for consistent dimensional quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces.

Ensure the workpiece is properly fixtured and the machine is set to an appropriate spindle speed and feed rate for the material being drilled. Wear appropriate PPE including eye protection when operating drilling equipment. Never exceed the maximum recommended drilling depth of 0.737 inches per the manufacturer specification without a peck-drilling cycle to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.191 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4409 inches (62.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0236 inches (26.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.737 inches (18.73 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\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: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\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\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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: 9005150048500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51752552923442,"sku":"9005150048500","price":30.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbe102cf79a0c87a2f3cab70a6ecfed3_61d8bec7-1788-4d9e-8cba-4e3bb16e07ca.jpg?v=1788929066","url":"https:\/\/voomisupply.com\/products\/guhring-9005150048500-screw-machine-drill-bit-0-191-in","provider":"Voomi Supply","version":"1.0","type":"link"}
