It measures 0.1495 inches in diameter and 3.0 inches in overall length, with a 1.875-inch flute length that supports drilling depths up to 1.875 inches. The 135-degree split point reduces walking on entry and requires less thrust than a 118-degree point, making it a practical choice for production and maintenance drilling. The web-thinned, tapered-web construction improves chip evacuation through the two regular-spiral flutes. Machinists, maintenance technicians, and tool-and-die tradespeople reach for this bit in everyday ferrous and non-ferrous drilling applications.\u003c\/p\u003e\u003cp\u003eThe 5996990 is suited for general-purpose drilling in steel, aluminum, and other non-ferrous materials, matching ISO material groups P, M, K, N, and S. The straight cylindrical shank at 0.1495 inches in diameter fits standard keyless and keyed drill chucks without adapters. It is at home in drill presses, hand drills, and CNC drilling operations where a short, rigid jobber-length bit is preferred over a screw-machine or long-series alternative. The QC21P series designation places this bit within a standard general-purpose HSS line manufactured to ANSI tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 25 wire size, 0.1495 inches diameter, for precision hole sizing between standard fractional increments\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and lowers feed force on harder materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip flow and reduces heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles steel, aluminum, and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for easy visual inspection of wear and regrind condition\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute, straight shank — fits standard drill chucks directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or stock drill bit for any application requiring a No. 25 wire-size hole in steel, aluminum, or non-ferrous materials.

Disconnect or lock out power to the drill press or machine tool before changing bits, per standard lockout-tagout procedure. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, noting that this bit does not support through-coolant delivery. Follow shop safety and applicable OSHA machine-guarding requirements when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous (ISO Groups P, M, K, N, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21P\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5996990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51707548107058,"sku":"5996990","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_c04d5125-b225-4289-ba9d-0e5d6be273ea.jpg?v=1788440898","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996990-no-25-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
