Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this bit measures 3.15 mm (0.1240 inches) in diameter with an overall length of 65 mm (2-9\/16 inches). The parabolic flute geometry promotes efficient chip evacuation and reduces cutting force, making it well suited to high-performance applications. A 130-degree point angle and web-thinned tip improve centering accuracy and reduce thrust requirements on entry. This is a right-hand cut bit with a straight-cylindrical shank conforming to DIN 338, designed for machinists, tool and die shops, and maintenance professionals who demand consistent, repeatable hole quality.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for use in aluminum and other non-ferrous metals, as well as a range of general-purpose workpiece materials. Its 5xD flute-to-diameter ratio supports drilling depths up to approximately 31.28 mm (1.231 inches), making it appropriate for through-hole and moderate depth blind-hole work on production lines, machine shops, and maintenance benches. The straight-cylindrical shank fits standard three-jaw drill chucks on bench drill presses, CNC machining centers, and hand-held power drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction with bright, uncoated finish for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design for improved chip evacuation and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web-thinned tip for accurate self-centering entry\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration reduces cutting resistance through the full drilling depth\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 Series 549 jobber length drill bit rated for aluminum (K), non-ferrous (N), and general-purpose steel (P) workpiece materials.

Ensure the chuck is fully tightened and the workpiece is securely fixtured before beginning the cut. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support coolant-through delivery. Inspect the cutting edges for wear before reuse, as a dull HSS bit increases thrust and reduces hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.15 mm (0.1240 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 65 mm (2-9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 29 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 31.28 mm (1.231 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003ePoint Type\u003c\/strong\u003e: Standard with Web Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.018 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Non-Ferrous, General Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 549\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: 9005490031500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750325354802,"sku":"9005490031500","price":20.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89b63dfaf6eec2dbad0254034aef38d2.jpg?v=1788914804","url":"https:\/\/voomisupply.com\/products\/guhring-9005490031500-jobber-drill-bit-3-15mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
