Built to ANSI standards, it features a 135-degree split point for self-centering entry without a center punch, a parabolic flute geometry for efficient chip evacuation, and a web-thinned, tapered web configuration for reduced thrust and cleaner hole entry. The straight shank measures 0.1285 inches in diameter, matching the No. 30 wire gauge size. At 3 inches of flute length relative to a 5-3\/8-inch overall length, this is a heavy-duty general-purpose bit suited for machinists, fabricators, and maintenance technicians working in production or field environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in alloy steel, carbon steel, hardened steel, tempered steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, magnesium, magnesium alloy, nickel, titanium, titanium alloy, and graphite. The 6xD flute-length-to-diameter ratio makes it well suited for deeper hole applications where a jobber-length bit would be too short. Right-hand cut configuration is standard for conventional drill press, mill, or hand-drill setups. Coolant-through capability is not included in this design.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point for self-centering entry, reducing walk and eliminating the need for a center punch in most applications\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast, efficient chip removal and reduces heat buildup in deep drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces cutting resistance and improves penetration in hard materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e6xD flute-to-diameter ratio gives added reach for deeper holes compared to standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eANSI-compliant, heavy-duty grade for production and general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with all standard straight-shank drill chucks accepting a 0.1285-inch shank diameter.

Ensure the work piece is securely clamped before drilling to prevent rotation or movement. Apply cutting fluid or coolant when drilling hardened steel, stainless steel, titanium, or other high-resistance alloys to extend tool life, even though the bit does not support through-coolant delivery. Inspect the cutting edges for wear before each use and replace when the point shows signs of chipping or dulling to maintain hole quality and prevent tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1285 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1285 inches\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy-Duty Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5997138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51690263085362,"sku":"5997138","price":27.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_39a32a38-4351-4340-9387-6dc113d136c8.jpg?v=1788267896","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997138-no-30-hss-taper-length-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
