Built from powdered metal and coated with GUHRING's proprietary multi-layer nano-FIREX finish, this bit delivers extended tool life and reduced heat buildup in demanding production environments. It carries a 130-degree point angle with cone relief geometry and a parabolic flute design that promotes fast chip evacuation. The overall length is 1.929 inches (49.00 mm), and the straight cylindrical shank measures 0.1283 inches (3.26 mm) in diameter. It conforms to DIN 1897 standards and is sized to wire gauge number 30, with a decimal inch diameter of 0.1285 inches. Intended for installation by machinists, tool and die technicians, and production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis bit fits standard drilling applications in ferrous materials, specifically steel and cast iron, where chip clearance and point stability are critical. The parabolic flute with fast spiral geometry is well suited to short-hole drilling cycles common in screw machine and CNC production work. With a flute-to-diameter ratio of 3xD and a maximum drilling depth of 0.516 inches (13.11 mm), it is optimized for stub-length reach. Series 515 is GUHRING's established line for high-productivity stub drilling in moderate to high-volume machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction for improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eMulti-layer nano-FIREX coating reduces friction and extends service life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with cone relief for accurate entry and reduced thrust on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with fast spiral promotes efficient chip evacuation in stub-depth holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned point reduces cutting forces and improves centering without a pilot\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with h8 diameter tolerance for consistent chuck grip and runout control\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1897 specification for screw machine length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit for use in standard drill chucks and collet systems accepting a 0.1283-inch straight shank.

De-energize and lock out the machine before changing or inspecting any cutting tool. Do not exceed the rated maximum drilling depth of 0.516 inches for this stub-length geometry without retracting to clear chips. No coolant-through capability is provided on this bit, so external coolant or cutting fluid should be applied at the entry point when drilling ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1285 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.929 inches (49.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7087 inches (18.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.516 inches (13.11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1283 inches (3.26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2205 inches (31.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Multi-layer nano-FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 pounds\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: 9005150032600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739869217074,"sku":"9005150032600","price":28.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3293a658ea3472a46006aac337f8128.jpg?v=1788819859","url":"https:\/\/voomisupply.com\/products\/guhring-9005150032600-size-30-stub-drill-bit-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
