It measures 0.147 inches in diameter (Wire Size 26) with an overall length of 2-1\/16 inches and a flute length of 1 inch. Constructed from high speed steel with a bright\/uncoated finish, this bit operates with a standard 118-degree point angle and a tapered, web-thinned configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. This is a Series R41 bit rated for general purpose and high-performance use per ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis screw machine length drill bit is well suited for metalworking applications where stub-length rigidity is required. Its primary rated workpiece material is titanium, making it appropriate for aerospace, medical, and precision machining environments where harder alloys are common. The shortened flute-to-diameter ratio of 2.5xD reduces deflection and improves hole location accuracy compared to jobber-length bits. Machinists, tool-and-die workers, and precision fabricators will find this bit appropriate for drill press, CNC, and hand-held power tool use in production and repair settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.147 inch diameter, Wire Size 26, screw machine (stub) length for added rigidity\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across general purpose and high-performance cuts\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute promotes efficient chip removal during drilling\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to affect dimensional tolerance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series R41 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for standard drill chucks accepting straight-cylindrical shanks; rated for use on titanium and suitable for other metals in general purpose machining applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a compatible drill chuck and tighten securely before use. Power down and de-energize the drilling machine before changing bits. Use appropriate cutting fluid or coolant when drilling titanium or other hard alloys to manage heat buildup, even though this bit does not feature through-coolant capability.
