Built from solid carbide with a coated finish, this bit produces clean, accurate holes in steel, alloy steel, and cast iron. The 140-degree point with R-thinned web geometry reduces thrust and improves centering at entry. Overall length is 3.5039 inches (89 mm), with a flute length of 1.85 inches (47 mm). The 2xD flute-to-diameter ratio and tapered web configuration are matched to short-hole, high-feed applications. This bit is sized at letter Q, equal to 0.3319 decimal inch (8.43 mm). Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\u003cp\u003eThe 630033111 is suited for screw machine, CNC lathe, and drill press operations where a stubby, rigid bit profile reduces deflection in short-hole drilling cycles. It performs in production environments cutting steel, alloy steel, and cast iron. The straight-cylindrical shank seats directly in standard drill chucks and collet holders. Right-hand cut, spiral flutes, and no coolant-through design make this a straightforward drop-in for dry or flood-cooled setups where internal coolant delivery is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life in steel and alloy steel cutting applications\u003c\/li\u003e\n\u003cli\u003eScrew machine length profile provides added stiffness and reduced runout versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003e2xD flute-to-diameter ratio matched to shallow, high-feed drilling cycles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production tooling option for operations requiring a letter Q screw machine length solid carbide drill bit in the OSG Series 6300 line.

Power down and lock out the machine spindle before changing tooling. Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before cutting. Solid carbide bits are brittle compared to high-speed steel and should not be used in setups with excessive vibration or unsupported workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3319 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 8.43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm (1.85 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89 mm (3.5039 inches)\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\u003c\/strong\u003e: 10 mm (0.0394 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\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: 2xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.155 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112801\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: 630033111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730252333362,"sku":"630033111","price":196.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92ac2d2de290359753c194556239fb2a_dc05ebca-525d-4fb3-b529-937b0aee6704.jpg?v=1788714140","url":"https:\/\/voomisupply.com\/products\/osg-630033111-drill-bit-letter-q-8-43mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
