Built to the HP253 series standard, it features a 140-degree split point with R-thinned web geometry that reduces entry force and improves hole accuracy. The straight-cylindrical shank measures 6.00 millimeters in diameter and seats securely in standard drill chucks and quick-change toolholders. Coolant-through capability supports chip evacuation and thermal management at elevated feed rates. This bit is sized at 5\/32 inch (0.1562 inches) and is intended for use by machinists, tool-and-die professionals, and CNC operators working in production environments.\u003c\/p\u003e\n\u003cp\u003eThe HP253-1563 is suited for drilling in steel, alloy steel, and cast iron in screw machine, CNC lathe, and machining center applications. The screw machine length format provides increased rigidity over jobber-length bits, making it a practical choice for short-hole drilling where runout control and positional accuracy matter. The 3xD flute-to-diameter ratio keeps the tool compact while maintaining adequate chip clearance. It is commonly used in short-run and production drilling operations where tool life and repeatability are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with R-thinned, tapered web for reduced thrust and clean entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat control at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3xD flute ratio) provides rigidity advantage over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute geometry suitable for steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet toolholders\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.

Ensure the machine spindle and toolholder are clean and free of debris before seating the shank to prevent runout. Carbide is brittle — avoid dropping or lateral impact. When coolant-through functionality is used, verify that the machine tool's coolant system pressure and flow rate are compatible with the tool before engaging the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 5\/32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eDrill Bit Size Range (Decimal Inch)\u003c\/strong\u003e: 0.1500 to 0.2000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP253\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: HP253-1563\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728518644018,"sku":"HP253-1563","price":76.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28449fa99ca46be7c04de7543621f9d1_320f1aa0-0e14-4691-829c-c86c9b58fccb.jpg?v=1788692581","url":"https:\/\/voomisupply.com\/products\/osg-hp253-1563-carbide-screw-machine-drill-bit-5-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
