The bit measures 9\/32 inch (0.2813 inches) in diameter with a 118-degree standard point angle and a bright, uncoated high speed steel construction. Overall length is 4.25 inches with a 2.9375-inch spiral flute length, giving it the extended reach typical of jobber-length tooling. A web-thinned, tapered web design reduces thrust and improves chip evacuation. Installers, machinists, and tradespeople working in fabrication, HVAC rough-in, electrical, and plumbing applications will find this bit suitable for everyday production drilling.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in handheld drills, drill presses, and CNC or manual lathes running at appropriate surface speeds for high speed steel tooling. Primary workpiece materials include steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight-cylindrical shank fits standard three-jaw chucks without adapters. The Series R10H designation covers the general-purpose jobber family within the PRECISION TWIST DRILL lineup. Right-hand cut, two-flute spiral geometry moves chips out of the hole efficiently during through-hole and blind-hole drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9\/32 inch (0.2813 inches) diameter with matching straight-cylindrical shank for chuck compatibility\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry into steel and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright, uncoated finish — no coating buildup concerns on re-sharpening\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry with 2.9375-inch flute length supports efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eANSI-compliant construction; series R10H-R18H general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck sized to accept a 9\/32-inch straight-cylindrical shank.

Match spindle speed to the workpiece material and bit diameter following standard HSS surface-speed tables — running too fast in hard steel will shorten tool life significantly. Apply cutting fluid when drilling steel or titanium to extend edge life and improve hole finish. Inspect the cutting edges and point for wear or chipping before each use; a dull bit increases thrust and can cause workpiece damage or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\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: Bright, Uncoated\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: 0.2813 inches (9\/32 inch)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.9375 inches (2-15\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\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: R10H-R18H\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: 5998426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699583123762,"sku":"5998426","price":16.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac335c1d53632e99459aa82e5500dfd1_5a928d49-6d3e-4a71-ae95-3878adc3468c.jpg?v=1788377798","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998426-9-32-in-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
