It measures 0.2874 inches (7.30 mm) in diameter with an overall length of 2.9134 inches (74.00 mm) and a flute length of 1.3386 inches (34.00 mm). The 130-degree split point and parabolic flute geometry work together to reduce walking, improve chip evacuation, and lower thrust requirements. The web-thinned, parallel web construction further reduces cutting resistance at the tip. This bit is intended for use by machinists, tool and die technicians, and maintenance professionals running production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in aluminum workpieces and is well suited to CNC machining centers, drill presses, and screw machine setups where a compact stub-length tool provides better rigidity and reduced deflection versus jobber-length alternatives. The bright uncoated finish makes this bit suitable for non-ferrous and softer materials where coating adhesion or heat buildup is not the primary concern. Its 3xD flute-to-diameter ratio supports drilling depths up to 0.9070 inches (23.05 mm).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStub length design reduces deflection and improves rigidity in short-reach drilling applications\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip evacuation and lowers cutting forces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces tip thrust and walking tendency\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle optimized for entry into aluminum and similar non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated HSS finish suitable for non-ferrous and softer workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit conforming to DIN 1897 standards, suitable for use in standard drill chucks and collet holders accepting a straight-cylindrical shank at the 0.2874-inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with drill press or CNC machining center operation.
