It measures 1\/4 inch (0.2500 inches) in diameter with a 2.5 inch overall length and features a 135-degree split point for fast, self-centering starts without a center punch. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and extending tool life during deep or repetitive drilling operations. Made from high-speed steel (HSS) with a bright\/uncoated finish, this bit is suited for machinists, fabricators, and maintenance technicians working with ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThe 5997262 belongs to the QC41P series and is built for screw machine and short-hole drilling applications where rigidity and accuracy are critical. The stub length reduces deflection compared to jobber-length bits, making it well suited for drill presses, CNC turret lathes, screw machines, and hand-held operations on steel, cast iron, and similar ferrous workpieces. The straight cylindrical shank fits standard drill chucks without modification. This bit is sold individually but requires a minimum order of 12 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile improves chip flow and reduces clogging in deep holes\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.5 inches overall reduces deflection and increases rigidity\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration for lower cutting resistance\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles heat generated in ferrous-material drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting with straight cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel and cast iron as an OEM-style screw machine length bit in the QC41P series.

Ensure the machine spindle is fully stopped and locked out before changing bits. Secure the shank fully in the chuck to the recommended grip depth to prevent slippage and runout. Do not exceed the rated speed range for 1\/4 inch HSS tooling in the material being drilled, and use appropriate cutting fluid when drilling steel to prolong edge life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches (1-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC41P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5997262\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702495478066,"sku":"5997262","price":112.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66bfabf0a9e7051fa8ae2655b5798bc2_36725457-31b4-4e54-9831-ec859290f202.jpg?v=1788411486","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997262-1-4-inch-hss-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
