It carries a 140-degree split point (SU point type) with web thinning for self-centering entry, reducing the need for a center punch on most workpieces. The flute length measures 1.9685 inches and the overall length is 3.8189 inches. Coolant-through capability delivers cutting fluid directly to the cutting edge, improving chip evacuation and tool life in deep-hole operations. Licensed HVAC, plumbing, and mechanical contractors as well as machining professionals will find this bit suited to high-cycle production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use across a broad range of materials including brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy. Its 7xD flute-length-to-diameter ratio makes it well suited for taper-length drilling where extra reach beyond a jobber-length bit is required without stepping up to a full aircraft-extension length. The straight shank and standard 0.2362-inch shank diameter allow mounting in standard drill chucks and collet holders commonly found in machine shop and field drilling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron carbide grade for hardened and difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning provides self-centering entry and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels fluid to the cutting zone for improved chip evacuation and extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry compatible with standard drill press, lathe, and CNC spindle setups\u003c\/li\u003e\n  \u003cli\u003e7xD flute-length ratio delivers taper-length reach — 1.9685-inch flute, 3.8189-inch OAL\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 standard for consistent dimensional accuracy and interchangeability\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds rigidity along the flute for reduced deflection in harder substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide taper length drill bit for applications requiring a 13\/64-inch (0.2031-inch) diameter hole in brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, or titanium alloy.

Before mounting, ensure the spindle and chuck are fully de-energized and the machine is locked out per applicable safety procedures. Verify chuck or collet runout is within acceptable limits before drilling — excessive runout accelerates carbide tool wear and can cause breakage. Do not exceed the manufacturer-rated feed and speed parameters for the material being drilled, and ensure coolant supply lines are open and flowing before initiating a cut when using coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 13\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2031 inches\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\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\u003eFlute Length\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.8189 inches (90.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 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\u003eShank Type\u003c\/strong\u003e: Straight, Non-Threaded\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 to Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6640 inches (42.26 mm)\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 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: 0.08 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: 9055120051600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51744585122098,"sku":"9055120051600","price":313.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f35acc43e799d2200a752064f9fc3344.jpg?v=1788858655","url":"https:\/\/voomisupply.com\/products\/guhring-9055120051600-taper-length-drill-bit-0-2031-in","provider":"Voomi Supply","version":"1.0","type":"link"}
