Built from powdered metal and coated with GUHRING nano-FIREX multi-layer coating, the bit delivers extended tool life in demanding production environments. It features a 130-degree point angle with cone relief geometry and a parabolic flute profile that promotes fast chip evacuation. The overall length is 2.598 inches (66.00 mm), flute length is 1.102 inches (28.00 mm), and maximum drilling depth reaches 0.761 inches (19.32 mm). This is a right-hand cutting, straight-shank bit conforming to DIN 1897. Machinists, tool-and-die technicians, and maintenance professionals install this bit in screw machines, CNC drill presses, and hand-held production setups.\u003c\/p\u003e\n\u003cp\u003eThe 9005150057900 is sized for wire size Number 1 (0.2280 inch decimal equivalent) and falls within the 0.2000 to 0.2500 inch diameter range. Its stub length and parabolic flute make it well suited for short, precise holes in production runs on steel and cast iron workpieces where chip packing and heat buildup are common concerns. The web-thinned point reduces thrust force at entry, making it practical for both CNC machining centers and manual drill press operations requiring accurate hole positioning without a pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction with nano-FIREX multi-layer coating for extended wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree cone relief point angle reduces thrust and improves centering on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eParabolic fast-spiral flute (3xD flute-to-diameter ratio) promotes efficient chip evacuation in deep passes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers cutting force at entry without sacrificing point stability\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank (0.2280 inch diameter, h8 tolerance) fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 stub-length standard ensures consistent fitment in production tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct production substitute for stub-length drill bits conforming to DIN 1897 in wire size Number 1 (0.2280 inch).

Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck runout is within acceptable limits for the h8 shank tolerance to avoid premature wear or hole-size deviation. Coolant-through is not supported on this bit; apply external cutting fluid appropriate for the workpiece material when drilling steel or cast iron at sustained depths.\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: Number 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.598 inches (66.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.102 inches (28.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.761 inches (19.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2280 inches (5.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.496 inches (38.00 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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eDrill Bit 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: nano-FIREX Multi-layer\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\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: 0.025 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: 9005150057900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739864334642,"sku":"9005150057900","price":35.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22b616991e059682d7ad5b90dfabde57.jpg?v=1788819794","url":"https:\/\/voomisupply.com\/products\/guhring-9005150057900-screw-machine-drill-bit-size-1","provider":"Voomi Supply","version":"1.0","type":"link"}
