Measuring 0.375 inches in diameter with an overall length of approximately 6.38 inches (162 mm), this bit features a 140-degree split point and a FIREX coating finish that reduces friction and extends tool life under high-cycle production conditions. The straight-cylindrical shank diameter measures 0.3937 inches, making it compatible with standard chucks and collets. Built to DIN 6537 standards and classified as a high-performance grade tool, it is suited for use by machining professionals, tool-and-die shops, and maintenance technicians working with cast iron, steel, aluminum, and titanium alloy workpieces.\u003c\/p\u003e\n\u003cp\u003eThis Series 5525 drill bit is designed for deep-hole drilling with a flute-by-diameter ratio of 12xD, providing a maximum drilling depth of 4.162 inches (105.72 mm). The spiral flute design with a regular spiral type promotes consistent chip evacuation. Coolant-through capability supports high-feed-rate operations where heat buildup is a concern. Typical applications include facet point grinding setups and self-centering operations in production machining environments across both CNC and manual drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating finish reduces friction and improves tool life in ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-feed-rate deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point with web-thinned, tapered web for improved self-centering and reduced thrust\u003c\/li\u003e\n  \u003cli\u003e12xD flute-by-diameter ratio with a maximum drilling depth of 4.162 inches (105.72 mm)\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 6537 standard with right-hand cutting direction and two-flute spiral configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel as primary workpiece materials (ISO material codes K and P), with secondary compatibility for aluminum and titanium alloys (ISO material codes H, M, N, and S).

Ensure the machine spindle and workpiece are fully secured before initiating the drilling cycle. When using the coolant-through feature, verify that the coolant supply system is properly connected and pressurized per machine specifications. Carbide tooling is brittle and should not be subjected to lateral loading or interrupted cuts beyond the tool's rated application range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 162 mm (approximately 6.38 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 120 mm (approximately 4.72 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm (approximately 1.57 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.162 inches (105.72 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5525\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6537, California Proposition 65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 9055250095200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750735348018,"sku":"9055250095200","price":562.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7878a8d740abd916bdc46247c5df6e03_c7de5356-1548-4da1-9bd8-7f08aad48bef.jpg?v=1788919127","url":"https:\/\/voomisupply.com\/products\/guhring-9055250095200-extra-length-drill-bit-0-375in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
