Built from powdered metal (PMASP60 grade) with a coated finish, this bit measures 0.2969 inches (19\/64 inches) in diameter and delivers consistent performance in cast iron and steel. The parabolic flute geometry promotes efficient chip evacuation, while the web-thinned, cone-relief point reduces thrust and improves self-centering at entry. With an overall length of approximately 2.91 inches and a flute length of approximately 1.34 inches, this stub-length format provides added rigidity for accurate hole location in tight setups. Licensed HVAC, plumbing, and mechanical trades rely on stub-length bits where reach is limited and hole straightness matters.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling into cast iron and steel in residential and commercial mechanical applications, fabrication shops, and job-site conditions where a short, rigid bit reduces deflection. The 3xD flute-to-diameter ratio and parabolic flute design make it well-matched to CNC drilling centers, drill presses, and hand-held production drills running through ferrous materials. It follows DIN 1897 specification, making it a direct fit where metric-standard tooling is required. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders without modification.\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\u003eParabolic flute geometry with web thinning promotes fast chip evacuation and reduced thrust\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with cone relief improves entry stability in cast iron and steel\u003c\/li\u003e\n\u003cli\u003eStub length (DIN 1897) adds rigidity and minimizes deflection in short-reach applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 1.011 inches supports typical through-hole work in production settings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit for use in standard drill chucks and collet systems; primary workpiece materials are cast iron and steel.

Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before drilling. Do not exceed the recommended maximum drilling depth of 1.011 inches per pass without retracting to clear chips. Always wear appropriate eye protection and follow applicable OSHA machine-guarding requirements when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2969 inches (19\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (approximately 2.91 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (approximately 1.34 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.011 inches (25.69 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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 by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: +0.000 to -0.022 mm\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\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: 0.07 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: 9005150075400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739118698802,"sku":"9005150075400","price":54.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6d06e73d68c66ed9f3a0651234b3409.jpg?v=1788809737","url":"https:\/\/voomisupply.com\/products\/guhring-9005150075400-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
