Built from submicron-grade solid carbide and coated with AlTiN, it handles alloy steel, cast iron, and stainless steel without the heat failure common to HSS tooling. The 140-degree split point geometry reduces walking and cuts entry force, while the web-thinned, parallel-web configuration improves chip evacuation. At 9\/32 inch (0.2812 inch) diameter with a 2.9921-inch overall length, this stub-length bit fits tight-clearance setups where standard-length drills cannot reach. Coolant-through design supports high-speed, deep-hole drilling cycles. Weighs 0.1 pounds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and production drilling operations working in ferrous materials including alloy steel, cast iron, and stainless steel. The screw machine (stub) length format provides rigidity and reduces deflection in short-reach applications. The straight cylindrical shank fits standard drill chucks and collets without modification. It is a practical choice for tool-and-die shops, machine shops, and maintenance professionals running tight-tolerance work in hard metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for extended tool life in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides oxidation resistance and thermal hardness at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point with web thinning reduces thrust force and minimizes drill walk\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports through-spindle coolant for deep-hole and high-speed applications\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard chucks and ER collet systems\u003c\/li\u003e\n  \u003cli\u003eDrill bit diameter tolerance of +0.0000 to -0.0005 inch for consistent, close-tolerance hole production\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in CNC machining centers, drill presses, and manual machines equipped with standard straight-shank toolholders or collet chucks accepting an 8.00 mm (0.3150 inch) shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified machinist familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and free of runout before seating the shank, as carbide is brittle and sensitive to side loads caused by excessive runout. Power down and lock out the machine before changing tooling. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material to avoid premature chipping or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/32 inch (0.2812 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9921 inches (76.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inch (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9370 inches (49.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: Parallel, Web-Thinned\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: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Cast Iron, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ASSC140-AT-CL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77713105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51997847552306,"sku":"77713105","price":169.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f8cbabe2c5d0b8640d63a961af6c905.jpg?v=1789994424","url":"https:\/\/voomisupply.com\/products\/accupro-77713105-screw-machine-drill-bit-9-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
