Built to DIN 6537 standards, it features a 140-degree split point (SU point type) with web thinning for self-centering entry without a center drill. The 7xD flute-to-diameter ratio provides extended reach in a taper length format. At 0.2756 inches (7.00 mm) diameter with a 0.3150-inch straight shank, this drill is sized for machine tool chucks and collet holders used in CNC and manual machining operations. Coolant-through capability supports chip evacuation and tool life in deep-hole applications.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for production and job-shop machining of difficult materials including stainless steel, hardened materials, nickel alloys, titanium alloy, cast iron, brass, and steel. Its spiral flute geometry and submicron carbide substrate make it appropriate for applications where standard HSS drills fail to hold tolerance or wear prematurely. Machinists and CNC operators working in aerospace, medical, and general metalworking will find this drill appropriate for through-hole and blind-hole work in fixured setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for hardened and exotic material applications\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning enables self-centering without a spotting operation\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and heat management in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e7xD flute-to-diameter ratio allows drilling depths up to 2.579 inches (65.50 mm)\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut spiral flute with tapered web configuration per DIN 6537\u003c\/li\u003e\n  \u003cli\u003eCoated finish for extended tool life across a broad material range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or production tooling option for Series 5512 applications; compatible with standard straight-shank chucks and collet systems accepting a 0.3150-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation of this drill should be performed by a qualified machinist or CNC operator familiar with carbide tooling requirements. Secure the straight shank in a precision collet or drill chuck rated for the intended spindle speed before use. Carbide tooling is brittle and susceptible to breakage from side loading, interrupted cuts without proper feed rates, and workpiece movement — ensure the workpiece is rigidly fixtured. Always verify spindle speed and feed rate against manufacturer tooling data for the specific workpiece material before beginning the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 76.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 116.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.579 inches (65.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5748 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, web-thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight, non-threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5512\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 9055120070000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730006868274,"sku":"9055120070000","price":365.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fbf92b61bc9d7082fe6e6ccf22db9a4.jpg?v=1788710061","url":"https:\/\/voomisupply.com\/products\/guhring-9055120070000-taper-length-drill-bit-0-2756-in","provider":"Voomi Supply","version":"1.0","type":"link"}
