Ground from high-speed steel (HSS) with a steam oxide coating, it delivers solid wear resistance and reduced friction during the cut. The 135-degree split point starts on contact without center-punching and resists walking on hard or curved surfaces. At 4.25 inches overall length with a 2.9375-inch flute, this bit fits standard drill chucks and most benchtop or handheld drilling setups. Two spiral flutes clear chips efficiently. A tapered web with web thinning reduces thrust and improves chip evacuation in deeper holes.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It follows a 10xD flute-to-diameter ratio, making it a practical choice for production drilling, maintenance work, and fabrication applications where a reliable jobber-length HSS bit is needed. The straight cylindrical shank measures 9\/32 inch in diameter, fitting directly into standard drill chucks without adapters. Series R10B is rated for heavy-duty use and conforms to ANSI and NAS 907 standards, making it appropriate for aerospace, industrial, and mechanical trade work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-starting cuts and reduced walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with steam oxide coating for wear resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with regular helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and NAS 907 standards; rated heavy-duty for demanding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 9\/32-inch straight cylindrical shank.

Machinists, maintenance mechanics, and fabricators typically handle installation. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to extend tool life and maintain hole quality. Inspect the bit for chipping or dulling before each use and replace if the cutting edge is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9\/32 inch (0.2813 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\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.9375 inches (2-15\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.9375 inches\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\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 5998041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51697119068466,"sku":"5998041","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e54529b321c8d88e787e6c4f803d17c6_2c1958ea-74f8-4aa5-b420-11c19f5d357b.jpg?v=1788349591","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998041-jobber-drill-bit-9-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
