Built from high speed steel with a coated finish, this bit measures 1.0625 inches in diameter and features a standard 118-degree point angle with a straight-cylindrical shank for secure chuck engagement. The spiral flute geometry and right-hand cut deliver efficient chip evacuation. At 6.25 inches overall length and a 4-inch flute length, it provides the shorter body profile typical of screw machine length tooling, offering added rigidity in tight setups.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in Series R40 applications and is listed with titanium as the primary workpiece material, making it a capable choice for machinists and trade professionals working with hard or abrasive materials. The 2.5xD flute-to-diameter ratio supports controlled chip removal in deeper passes. It meets ANSI standards and is classified as a general-purpose grade suitable for production drilling environments where consistent hole quality is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.0625-inch diameter with 118-degree standard point angle for clean entry and accurate positioning\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (6.25 inches overall) provides increased rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; rated for titanium and other high-performance workpiece materials\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 drill bit for production and maintenance drilling setups requiring a 1.0625-inch diameter, straight-shank tool meeting ANSI specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and trade professionals using standard drill chucks or collet systems rated for the shank diameter. Ensure the machine spindle and chuck are fully stopped and locked out before changing tooling. Verify chuck or collet runout before use to maintain hole accuracy and extend tool life.
