Built from powdered metal (PMASP60 grade) with a coated finish, it delivers consistent performance in cast iron and steel applications. The bit measures 0.1094 inches (7\/64 inch) in diameter with a 130-degree drill point angle and a parabolic flute geometry that promotes efficient chip evacuation. Overall length is 1.811 inches, making it well-suited for short-reach, high-cycle drilling operations. The web-thinned, parallel web configuration reduces entry force and improves hole quality. Licensed tradespeople and machinists rely on this series for repeatable results in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is appropriate for drilling cast iron and steel workpieces in both light manufacturing and maintenance repair operations. Its stub length format provides added rigidity compared to jobber-length bits, reducing deflection in close-tolerance setups. The Series 515 designation follows DIN 1897 standards, making it a recognized specification in CNC machining centers, drill presses, and hand-held pneumatic tools where a straight-cylindrical shank is required. Right-hand cut direction is standard for conventional drilling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction (PMASP60) with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with web thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes chip evacuation at a 3xD flute-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eStub length format adds rigidity and reduces deflection in tight-clearance drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without modification\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 1897 specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification stub drill bit per DIN 1897 standards, compatible with any drill press, CNC machining center, or pneumatic drill accepting a 0.1094-inch straight-cylindrical shank.

Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Disconnect power or depressurize the tool before changing bits. Do not exceed the maximum drilling depth of 0.466 inches in a single pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/64 inch (0.1094 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal (PMASP60)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eFlute Length\u003c\/strong\u003e: 0.6299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1094 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.466 inches\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: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\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 Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005150027800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731796427058,"sku":"9005150027800","price":25.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b66a704c3325fe280dc69714b0eed790.jpg?v=1788735037","url":"https:\/\/voomisupply.com\/products\/guhring-9005150027800-screw-machine-drill-bit-7-64","provider":"Voomi Supply","version":"1.0","type":"link"}
