Built from solid carbide and coated with TiAlN, this bit delivers heat resistance and extended tool life in demanding production environments. It measures 0.0827 inches (2.10 mm) in diameter with a 140-degree split point and R-thinned web for reduced thrust at entry. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is approximately 1.77 inches (45.00 mm). The two-flute spiral design runs at a 3xD flute-to-diameter ratio with a tapered web configuration. This bit is sized for precision work and is suited for machinists and tool-and-die professionals running production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe HP243-0827 is built for drilling steel, alloy steel, and cast iron in screw machine and short-hole applications. The screw machine length profile fits standard drill chucks and collet toolholders used in CNC machining centers, drill presses, and automatic screw machines. Right-hand cutting direction and regular spiral flutes support efficient chip evacuation in interrupted and continuous cuts. The TiAlN coating helps maintain cutting-edge integrity at elevated spindle speeds typical in production runs on ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides thermal protection and extends tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces walking and improves entry accuracy\u003c\/li\u003e\n  \u003cli\u003eR-thinned web minimizes thrust force and supports clean hole entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine length for improved rigidity and reduced deflection in short-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design with tapered web for effective chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces.

Secure the shank fully in a collet or drill chuck rated for the shank diameter before operation. Inspect the cutting edge for chips or wear before each use and replace if the edge is compromised. Follow machine manufacturer guidelines for spindle speed, feed rate, and clamping force appropriate to the workpiece material and hole depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0827 inches (2.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45.00 mm (approximately 1.77 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: TiAlN\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\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP243\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: HP243-0827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736880808242,"sku":"HP243-0827","price":36.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/071140dfd8ef9e6d649ede5c0472ae55.jpg?v=1788781472","url":"https:\/\/voomisupply.com\/products\/osg-hp243-0827-screw-machine-drill-bit-0-0827-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
