Built to DIN 6537L standards, it features a 140-degree split point (SU point type) with web thinning for self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance, extending tool life in demanding production environments. At 118 millimeters overall length with a 71-millimeter flute length, this is a two-flute, right-hand spiral bit suited for CNC machining centers and production drilling operations where dimensional consistency and tool longevity are priorities.\u003c\/p\u003e\u003cp\u003eThis bit is rated for cast iron and steel workpiece materials (ISO material codes K and P). The 5xD flute-to-diameter ratio and tapered web configuration support efficient chip evacuation in moderate-depth holes. The straight-cylindrical shank at 12 millimeters diameter seats securely in standard ER collet chucks and drill chucks. It is appropriate for both job shop and production floor environments where a high-performance carbide tool is specified over HSS alternatives. Coolant-through is not supported on this model.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron-grade material for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eFIREX coating for heat and wear resistance in steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning for self-centering entry\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chuck tooling\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6535 and DIN 6537L standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and production drilling setups targeting cast iron and steel workpieces (ISO K and P material groups) where a solid carbide jobber-length drill conforming to DIN 6537L is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist familiar with carbide tooling requirements. Secure the straight-cylindrical shank fully in a concentric ER collet or precision drill chuck to within manufacturer runout tolerances before operation. Carbide tooling is brittle — avoid interrupted cuts, lateral loading, or manual hand-drill use, which can cause sudden fracture. Set spindle speed and feed rate per material-specific carbide drilling parameters before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eOverall Length\u003c\/strong\u003e: 118 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Helix\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 by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.162 inches (54.92 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.007 to 0.025 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel (ISO K and P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9055150107200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51746531672370,"sku":"9055150107200","price":330.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_62b8e131-8877-4ba4-b652-7fc50fc1bdd7.jpg?v=1788871060","url":"https:\/\/voomisupply.com\/products\/guhring-9055150107200-carbide-drill-bit-27-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
