Built from M42 cobalt steel, it handles tough workpiece materials including alloy steels and aluminum without sacrificing edge life. The 135-degree split point reduces thrust and self-centers on contact, eliminating the need for a center punch in most setups. At 1-13\/16 inches overall length with a 13\/16-inch flute length, this stub-length geometry provides rigidity and minimizes deflection in short-reach drilling operations. Parabolic flutes promote efficient chip evacuation. Diameter tolerance is held to +0.0000 to -0.0005 inches, consistent with ASME B94.11M standards.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling environments where hole accuracy and tool longevity matter. The screw machine length format is the right choice when drill press quill travel is limited or when drilling on a CNC machining center, turret lathe, or screw machine. Primary workpiece materials include alloy steel and aluminum. The straight-cylindrical shank accepts standard three-jaw chucks and collet-style holders without modification. It is a single-unit item, packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for extended tool life in abrasive and hard alloy materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point for reduced thrust and self-starting entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes fast, clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eDiameter held to ASME B94.11M tolerance: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for No. 39 wire size screw machine drill bits in standard three-jaw chucks and collet holders used on drill presses, CNC machining centers, turret lathes, and screw machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians.
