Built from high speed steel with a coated finish, it measures 0.1654 inches (4.20 mm) in diameter with an overall length of approximately 2.60 inches (66.00 mm) and a flute length of approximately 0.87 inches (22.00 mm). The 120-degree faceted point and web-thinned, tapered web construction reduce entry force and improve centering accuracy. A right-hand spiral flute geometry handles chip evacuation efficiently across a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling, screw machine setups, and CNC or manual drill press operations where a shorter, stiffer drill body is preferred over jobber-length bits. The stub length reduces deflection in tight-clearance or high-feed-rate applications. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The straight-cylindrical shank with a 6.00 mm (approximately 0.236 inch) diameter seats securely in standard drill chucks and quick-change toolholders without additional adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point reduces walking and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web lowers thrust requirements and eases penetration into harder materials\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body minimizes deflection in high-feed and production drilling setups\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry supports efficient chip evacuation across steel and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute design compatible with standard drill press and CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OSG Series 1100 screw machine length drill bit suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.
