It measures 0.2283 inches (5.80 mm) in diameter and features a 140-degree split point with R-thinned web geometry for improved centering and reduced thrust. At 66.00 mm overall length with a 28.00 mm flute length, this is a stub-length tool built for rigidity in short-hole applications. Coolant-through capability makes it well suited for high-speed CNC machining centers where heat management is critical. Right-hand cut with a regular spiral and straight cylindrical shank rounds out the design.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for production drilling environments where tool life and hole accuracy matter. The HP253 series targets ferrous materials including mild steel, alloy steel, and cast iron in both job shop and high-volume manufacturing settings. The 3xD flute-to-diameter ratio and screw machine length keep deflection low when drilling from a turret, gang drill, or machining center. Machinists and tooling specialists working on precision components will find the tight diameter tolerance of plus 0.004 to plus 0.016 mm useful for near-net-size holes ahead of reaming.\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 thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed wet drilling on CNC equipment\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length minimizes deflection in short-reach applications\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0.004 to plus 0.016 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces. Part of the OSG HP253 series covering the 0.2000 to 0.2500 inch (5.00 to 6.50 mm) diameter range.

Secure the shank fully in a collet or drill chuck rated for the spindle speed being used — carbide is brittle and sensitive to side loading or improper runout. Always verify coolant flow before running at full speed when using the through-coolant feature. Do not use carbide drills in hand-drill applications or in machines with excessive spindle runout, as carbide does not flex and will fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2283 inches (5.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: plus 0.004 to plus 0.016 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\u003eWeight\u003c\/strong\u003e: 0.048 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: HP253-2283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739195998514,"sku":"HP253-2283","price":87.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05a70e75fc91c056c7b0565feb496694.jpg?v=1788811189","url":"https:\/\/voomisupply.com\/products\/osg-hp253-2283-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
