Built from high speed steel (HSS) with a bright\/uncoated finish, this Series 501 bit features a 130-degree point angle and a parabolic flute geometry with web thinning for improved chip evacuation and reduced thrust. The cylindrical shank measures 1\/8 inch in diameter, matching the 0.1250-inch drill diameter. Overall length is 4-3\/16 inches, with a flute length of 2-23\/32 inches and a 10xD flute-to-diameter ratio. Diameter tolerance is held to +0.000 to -0.018 mm, making it suitable for close-tolerance work.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in aluminum alloy and steel. The parabolic flute design promotes efficient chip flow in deeper holes, and the web-thinned, parallel web construction reduces the force needed at the point. It is a general purpose, right-hand cut bit suited for manual drilling, drill presses, CNC machining centers, and similar setups where a taper length reach is needed beyond what a jobber-length bit provides. Maximum drilling depth is 2.530 inches (64.25 mm). The bit conforms to DIN 340 specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for durability across aluminum alloy and steel workpieces\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web-thinned, parallel web for reduced entry force\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes chip evacuation in deeper cuts\u003c\/li\u003e\n\u003cli\u003e10xD flute-to-diameter ratio supports drilling to 2.530 inches maximum depth\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish, right-hand cut, cylindrical shank\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 340 specification for taper length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use taper length drill bit for standard 1\/8-inch cylindrical shank tool holders, drill chucks, and collets used in general machining and fabrication setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and de-energized before inserting or removing the bit from the chuck or collet. Confirm the shank is fully seated and the chuck is properly tightened before initiating a cut. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed rates appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-23\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.530 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum Alloy, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\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: 9005010031700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734256615730,"sku":"9005010031700","price":31.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3b0bb478451aa076e6a83a6150a6896.jpg?v=1788761562","url":"https:\/\/voomisupply.com\/products\/guhring-9005010031700-taper-length-drill-bit-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
