With a 5.70 mm diameter and a 140-degree point angle, this bit delivers accurate, controlled entry into ferrous metals including steel, alloy steel, and cast iron. The EgiAs coating reduces friction and extends tool life under demanding cycle times. At 66.00 mm overall length with a 28.00 mm flute length, the screw machine geometry keeps the bit rigid and minimizes deflection in short-hole drilling operations. Coolant-through capability supports high-speed machining setups. This bit is sized for machinists, tool-and-die shops, and production drilling environments.\u003c\/p\u003e\n\u003cp\u003eThe HP253-2244 is built for production drilling in steel, alloy steel, and cast iron workpieces. The screw machine length format is suited for CNC machining centers, drill presses, and turret lathes where stub-length rigidity is needed. The 3xD flute-to-diameter ratio and R-thinned point type reduce thrust and improve chip evacuation in through-hole and blind-hole applications. The straight-cylindrical shank at 6.00 mm diameter fits standard collets and drill chucks across common machine tool setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating reduces friction and extends tool life in high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web for reduced thrust and accurate entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed and high-feed machining\u003c\/li\u003e\n  \u003cli\u003eScrew machine length geometry minimizes deflection in short-reach drilling\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral configuration promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production tooling option for machining operations requiring a 5.70 mm solid carbide screw machine drill in steel, alloy steel, and cast iron workpieces.

Verify collet or chuck bore matches the 6.00 mm straight-cylindrical shank before seating the tool. Coolant-through setups should be confirmed for proper flow and pressure before initiating a cut. Do not exceed the machine spindle speed and feed rate ratings for solid carbide tooling in the workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.70 mm (0.2244 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\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 (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP253\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.048 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP253-2244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738468876594,"sku":"HP253-2244","price":87.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c659860536c45ed6ba5602d671410907.jpg?v=1788799930","url":"https:\/\/voomisupply.com\/products\/osg-hp253-2244-carbide-screw-machine-drill-bit-5-70mm","provider":"Voomi Supply","version":"1.0","type":"link"}
