Built to DIN 6537 standards, it features a 140-degree split-point (SU) tip with web thinning for self-centering entry without a pilot hole. The 0.2570-inch diameter bit runs a 7xD flute-to-diameter ratio, giving it the reach needed for deeper bores while maintaining rigidity. Coolant-through capability supports high-speed operation in difficult materials. Right-hand spiral flutes evacuate chips efficiently, reducing heat buildup and extending tool life in production drilling environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling brass, cast iron, hardened materials, nickel alloys, stainless steel, steel, and titanium alloy. The straight shank and 0.3150-inch shank diameter make it compatible with standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual production setups. It is a Series 5512 tool, appropriate for shops and field machinists who need a reliable, coated carbide drill in the F letter-size range for tight-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron-grade material for hardened and exotic alloy drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point geometry with web thinning for self-centering, no pilot hole required\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed and high-feed drilling cycles\u003c\/li\u003e\n  \u003cli\u003e7xD flute length ratio provides extended reach with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCoated finish for improved wear resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks and collet systems; compatible with material applications including brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy as specified by the manufacturer for Series 5512.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling professional. Ensure the machine spindle and chuck are fully stopped and locked out before inserting or removing the bit. Verify chuck or collet bore size accommodates the 0.3150-inch shank diameter before seating. When using coolant-through capability, confirm the machine spindle is equipped for through-spindle coolant delivery at the appropriate pressure for the material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2570 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 66.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 106.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.2130 inches (56.21 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight, Non-Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5748 inches\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: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eMaterial Application\u003c\/strong\u003e: Brass; Cast Iron; Hardened Materials; Nickel Alloy; Stainless Steel; Steel; Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5512\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 9055120065300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737152880946,"sku":"9055120065300","price":329.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7571396375132f3b60b8a80dd096612.jpg?v=1788784981","url":"https:\/\/voomisupply.com\/products\/guhring-9055120065300-taper-length-drill-bit-0-2570-in","provider":"Voomi Supply","version":"1.0","type":"link"}
