The 135-degree split point reduces walking on entry and lowers thrust requirements, making it well suited for production drilling and repetitive hole-making tasks. The web-thinned, parallel-web construction improves chip evacuation and extends cutting life. At 2.75 inches overall length, the shortened screw machine profile provides added rigidity compared to jobber-length bits, which reduces deflection in tight setups or drill press fixtures. Right-hand cut, two-flute spiral geometry handles a range of metals and light alloys.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on alloy steels and aluminum, making it a practical choice for machine shops, maintenance technicians, and fabrication pros working with metal stock, structural components, or machined assemblies. The straight-cylindrical shank fits standard drill chucks without adapters. The screw machine length format is common in CNC turret applications, drill press work, and hand-drill operations where stub rigidity is preferred over extended reach. Series 2330 conforms to ASME B94.11M and NAS 907 Type C specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter M size — 0.2950 inches diameter with a tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and cutting thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web design promotes chip clearance and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.75 inches OAL for maximum rigidity in confined setups\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for heavy-duty drilling applications\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and NAS 907 Type C standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.2950-inch straight-cylindrical shank.
