Manufactured from powdered metal (PMASP60 grade) with a coated finish, this bit delivers consistent performance in cast iron and steel applications. It features a 2-flute parabolic geometry that improves chip evacuation and reduces heat buildup during drilling. The 130-degree point angle with web thinning allows for faster penetration and improved self-centering on the workpiece. At 2.0472 inches overall length with a 0.1378-inch diameter, it fits standard straight-cylindrical chuck systems. Licensed tradespeople and machining technicians use this bit in production drilling and CNC screw machine operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for stub-length applications where rigidity is critical and axial runout must be minimized. The parabolic flute design with a parallel web configuration handles interrupted cuts and short-hole drilling in cast iron and steel workpieces. A maximum drilling depth of 0.5810 inches makes it appropriate for through-hole and shallow blind-hole operations in metal fabrication, job shop, and production machining settings. The Series 515 designation conforms to DIN 1897 specification for stub-length twist drills, making it a recognized standard in industrial tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal (PMASP60) construction with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web thinning improves entry and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eParabolic 2-flute geometry with parallel web for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.1378 inches diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eDIN 1897 compliant stub-length design provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with no coolant-through requirement simplifies setup on standard drilling equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub drill conforming to DIN 1897 standards, suitable for use in standard straight-shank drill chucks, collets, and CNC turrets accepting 0.1378-inch shank tooling used in production machining of cast iron and steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool selection and machine setup. Secure the shank fully in the chuck or collet and verify runout before production use. Ensure spindle speed and feed rate are set according to the workpiece material and machine specifications before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1378 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0472 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1378 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2598 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5810 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal (PMASP60)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 9005150035000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727817965874,"sku":"9005150035000","price":196.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c36fec4a286829156694ed27126805d4.jpg?v=1788682962","url":"https:\/\/voomisupply.com\/products\/guhring-9005150035000-stub-drill-bit-0-1378-in-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
