Built from high-speed steel (HSS) with a bright\/uncoated finish, it is designed for production drilling in metals and alloys where a longer reach than a jobber-length bit is required. The parabolic flute profile improves chip evacuation and reduces heat buildup during extended drilling cycles. Machinists, tool-and-die technicians, and maintenance professionals use this bit in drill presses, CNC machines, and manual drilling operations where depth and precision are critical.\u003c\/p\u003e\u003cp\u003eThis taper length drill bit is suited for drilling aluminum alloy, cast iron, and steel in both job-shop and production environments. The 10xD flute-to-diameter ratio and taper length body give it the reach needed for through-holes and deeper bores that standard jobber-length bits cannot access. It is a right-hand cut tool with a cylindrical (straight) shank, making it compatible with standard drill chucks and collet holders. Typical applications include structural fabrication, maintenance repair, and precision machining where hole depth and chip clearance are primary concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter E (1\/4 inch \/ 0.2500 inch) drill diameter with tight tolerance: +0.000 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web thinning for reduced thrust and easier entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eTaper length body with 3-13\/16 inch flute length and 5-13\/16 inch overall length for extended reach\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with bright\/uncoated finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight cylindrical shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 340 specification; rated High Performance grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling aluminum alloy, cast iron, and steel.

Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always power down and de-energize the machine before changing tooling. Follow applicable machine guarding requirements and use appropriate cutting fluid or coolant for the workpiece material to maximize tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 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 Length\u003c\/strong\u003e: 3-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.444 inches (87.48 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: approximately 2 inches (51.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-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: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\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, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum Alloy, Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 9005350063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51787535876402,"sku":"9005350063500","price":57.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78892b555350f8b4505c777b9b167f38.jpg?v=1789215779","url":"https:\/\/voomisupply.com\/products\/guhring-9005350063500-taper-length-drill-bit-1-4-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
