Built from heavy-duty high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in demanding applications. The 135-degree split point reduces the force needed to start a hole and eliminates the need for a center punch on most materials. At 3-1\/16 inches overall length and a 23\/64-inch diameter (0.3594 inches decimal), this bit is proportionally shorter than jobber-length equivalents, which improves rigidity and reduces deflection at higher feed rates.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are standard equipment in CNC machining centers, turret lathes, and drill presses where shorter tool projection improves accuracy and reduces chatter. The 2386860 suits production environments, fabrication shops, and maintenance operations where holes in the 0.3500 to 0.4000 inch diameter range are drilled repeatedly. The right-hand spiral flute and web-thinned parallel web configuration support efficient chip evacuation without coolant-through capability, making it appropriate for conventional flood or dry drilling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating extends tool life and reduces built-up edge on ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web improves chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eHeavy-duty high-speed steel construction rated for high-production use\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides greater rigidity than jobber-length equivalents\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight-cylindrical shank drill bit compatible with drill chucks and collet holders accepting 23\/64-inch shank diameters in drill presses, CNC machining centers, and turret lathes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered off and locked out per applicable OSHA lockout\/tagout procedures.
