At 7\/64 inch (0.1094 inch decimal) diameter and 1-13\/16 inches overall length, it is shorter than jobber-length bits, which reduces deflection and improves hole location accuracy in tight-clearance applications. The 135-degree split point starts on contact without a center punch and lowers the thrust needed to penetrate workpiece material. The parallel-web, web-thinned construction further reduces axial load. This bit is suited to production drilling and general metalworking where rigidity and repeatability matter.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits like the 2385839 are used in drill presses, CNC machining centers, turret lathes, and hand-held power drills wherever a stubby, rigid tool is preferred over a standard jobber bit. The short flute length of 13\/16 inches limits chip packing in shallow-hole drilling operations on steel, aluminum, cast iron, and similar materials. Machinists, tool-and-die workers, and maintenance mechanics reach for this format when drilling close to a shoulder, inside a confined space, or through a drill bushing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact and reduces required thrust, eliminating the need for a center punch on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web construction lowers axial cutting force and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction withstands the heat generated in continuous production drilling cycles\u003c\/li\u003e\n  \u003cli\u003eOxide surface finish adds a degree of surface hardness and light lubricity to reduce galling\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length minimizes deflection and improves positional accuracy versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, straight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty OEM-style replacement or stock drill bit for use in standard straight-shank drill chucks on drill presses, machining centers, and hand-held power drills accepting 7\/64 inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank fully into the chuck jaws and tighten with a chuck key before beginning any drilling operation. Power down and de-energize the machine before changing bits or adjusting workpiece fixturing. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life; this bit does not support through-coolant delivery. Inspect the split point for chipping before each use, as a damaged point will cause walking and inaccurate hole placement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 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\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 0.05 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: 2385839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737431605554,"sku":"2385839","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/583701d8b4bbe16bdd13ad45a7160561.jpg?v=1788788479","url":"https:\/\/voomisupply.com\/products\/hertel-2385839-screw-machine-drill-bit-7-64-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
