Built from high speed steel (HSS) with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. The 118-degree standard point angle and web-thinned, tapered web configuration allow for clean entry and efficient chip evacuation. At 5-7\/8 inches overall length with a 4-3\/8 inch flute length, the 85704641 fits standard drill chucks and machine spindles. Machinists, maintenance technicians, and general fabricators install this bit in drill presses, handheld drills, and CNC drilling setups.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for light to medium-duty drilling applications in general manufacturing, maintenance, and repair environments. The straight-cylindrical shank seats securely in three-jaw chucks without slipping under load. The right-hand spiral flute pulls chips up and out of the hole during drilling, reducing heat buildup and bit walking. The 31\/64 inch diameter falls within the 0.4000 to 0.5000 inch decimal range, making it a common size for through-hole and clearance-hole work in mild steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS construction with TiN coating for extended cutting life and reduced friction\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces thrust force and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix efficiently evacuates chips\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for secure seating in standard three-jaw chucks\u003c\/li\u003e\n  \u003cli\u003e5-7\/8 inch overall length provides jobber-standard reach for most benchtop and floor-standing drill presses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard three-jaw chucks accepting a 31\/64 inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a standard drill press, handheld drill, or CNC spindle. Secure the straight-cylindrical shank fully into the chuck and tighten all jaws before operation. Center-punch the workpiece before drilling to prevent walking at startup. Apply cutting fluid when drilling ferrous metals to manage heat and extend bit life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inch (0.4844 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/8 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 31\/64 inch\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\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.22 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85704641\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753676341554,"sku":"85704641","price":30.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8768b1d24c38e6081a0098b53becb003.jpg?v=1788939356","url":"https:\/\/voomisupply.com\/products\/hertel-85704641-jobber-drill-bit-31-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
