Built to Series 950E standards, it features a 118-degree standard point angle with web thinning for improved penetration and reduced thrust. The spiral, regular-helix flute geometry runs 7.5 inches in length, giving chips a clear path out of deep bores. At 10 inches overall length, this bit reaches where standard-length drills cannot. The straight-cylindrical shank measures 1\/2 inch in diameter and is compatible with standard drill chucks. Cutting direction is right-hand. This bit is suited for metalworking trades including HVAC, plumbing rough-in, and electrical installation where deep metal penetration through structural steel or cast iron is required.\u003c\/p\u003e\u003cp\u003eThe C09731 is designed for deeper drilling and long-reach drilling operations in cast iron and steel. It is a general-purpose grade bit appropriate for production shops, maintenance facilities, and field tradespeople who regularly drill through heavy-gauge metal assemblies, structural members, or equipment housings where bit reach is a limiting factor. The oxide finish provides mild surface protection during storage and initial use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-inch diameter with a diameter tolerance of +0.0000 to -0.0010 inches for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e10-inch overall length and 7.5-inch flute length for deep-hole and long-reach drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning and tapered web configuration for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry promotes efficient chip evacuation in deep bores\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for durability in cast iron and steel cutting\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/2-inch shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron and steel workpieces; suitable for use with standard drill presses, magnetic drills, and heavy-duty hand drills accepting a 1\/2-inch straight-cylindrical shank.

Always secure the workpiece before drilling and use appropriate cutting fluid or lubricant when drilling through cast iron or steel to extend bit life and manage heat. Ensure the drill motor is powered off and isolated before changing bits. Consult applicable safety standards and California Proposition 65 guidelines when working with high-speed steel tooling and metal swarf.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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: Spiral, Regular Helix\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 950E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI, California Proposition 65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C09731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692480168242,"sku":"C09731","price":74.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b55dc78b121be814e0c8d6d913bae96e.jpg?v=1788298164","url":"https:\/\/voomisupply.com\/products\/cleveland-c09731-extra-length-drill-bit-1-2-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
