Built from submicron solid carbide, this bit delivers the rigidity and edge retention required for consistent performance in production environments. The 140-degree split point (SU geometry) is web-thinned for self-centering entry, reducing the need for a center punch on most surfaces. Coolant-through design channels cutting fluid directly to the cutting edge, helping manage heat in deep-hole applications. Overall length is 131 millimeters (approximately 5.16 inches), and the drill diameter is 0.3281 inches (21\/64 inch).\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for use in CNC machining centers, drill presses, and multi-spindle setups where tight tolerances and difficult workpiece materials are routine. Material applications include brass, cast iron, hardened materials, nickel alloy, stainless steel, carbon and alloy steel, and titanium alloy. The straight shank (0.3937 inch diameter) fits standard ER and Weldon-style toolholders. Maximum drilling depth is 2.933 inches (74.51 mm), making it appropriate for through-holes and deep blind-hole applications within its 7xD flute-length-to-diameter ratio.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior hardness and wear resistance in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design for effective chip evacuation and heat management in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e7xD flute length ratio supports maximum drilling depth of 2.933 inches\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry promotes consistent chip flow in a right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 standard; diameter tolerance of +0.006 to +0.021 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 5512 OEM-style taper length drill compatible with standard straight-shank toolholders; suitable for machining brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy per the manufacturer material application rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or tooling technicians familiar with CNC or manual machine setup. Secure the straight shank in a balanced, appropriately sized collet or chuck before operation, and verify runout is within acceptable limits for the application. Always engage coolant flow before the cutting edge contacts the workpiece when using the through-coolant feature. Inspect the cutting edge for chipping or wear before each use, as solid carbide tooling can fracture if run in a compromised condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3281 inches (21\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eOverall Length\u003c\/strong\u003e: 131 mm (approximately 5.16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 87 mm (approximately 3.43 inches)\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: 2.933 inches (74.51 mm)\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: 1.7323 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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\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\u003eDiameter 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: 0.22 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: 9055120083300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730967003442,"sku":"9055120083300","price":432.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c968cd02b3824f902b4ff7cefedfe2c6.jpg?v=1788725439","url":"https:\/\/voomisupply.com\/products\/guhring-9055120083300-taper-length-drill-bit-0-3281-in","provider":"Voomi Supply","version":"1.0","type":"link"}
