Built from XPM high-speed steel with a coated finish, it measures 0.4921 inches (12.50 mm) in diameter and delivers tight tolerance drilling with a diameter tolerance of +0 to -0.027 mm. The 130-degree split point and R-thinned web reduce thrust and improve centering on hard materials. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary users of this bit in production drilling operations.\u003c\/p\u003e\u003cp\u003eThe 9599125 is suited for drilling steel, alloy steel, cast iron, and nickel alloy workpieces. Its screw machine length profile — shorter than a jobber bit — provides added rigidity and improved accuracy in tight setups, turret lathes, screw machines, and drill press fixtures. The 3xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes without coolant-through capability, making it appropriate for flood coolant or dry cutting setups depending on material and feed rate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eXPM high-performance coated construction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with R-thinned web for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides rigidity advantage over jobber-length bits in short-hole applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute geometry for efficient chip clearing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (12.00 mm) compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eTapered web configuration maintains edge strength from point to flute termination\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement drill bit for use with standard drill chucks, collet systems, and turret toolholders accepting a 12.00 mm straight-cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the bit. Seat the straight shank fully and evenly in the chuck or collet to prevent runout. Follow applicable machine manufacturer feed and speed recommendations for the target workpiece material — do not exceed rated speeds for HSS tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4921 inches (12.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 108.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 51.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: XPM High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Nickel Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.205 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9599125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727945498930,"sku":"9599125","price":146.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/475c85327368b29b00427489fc5c4904.jpg?v=1788684865","url":"https:\/\/voomisupply.com\/products\/osg-9599125-screw-machine-drill-bit-0-4921-in-xpm","provider":"Voomi Supply","version":"1.0","type":"link"}
