Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance across a wide range of shop and field applications. The 29\/64-inch diameter and 118-degree point angle make it well suited for standard through-hole and entry drilling tasks. At 3-9\/16 inches overall length, the stub-style body provides added rigidity compared to jobber-length bits, reducing deflection in short-hole applications. This bit is sold individually and is appropriate for use by machinists, maintenance technicians, and general tradespeople.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are commonly used in drill presses, CNC machines, and hand-held power drills where a shorter, stiffer bit is preferred over a standard jobber length. The 29\/64-inch size is a frequently called-for diameter for tapping and clearance holes in light fabrication, HVAC sheet metal, electrical enclosures, and plumbing fixture work. The right-hand cutting direction is compatible with standard drill chucks and rotating equipment without special configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across general-purpose drilling applications\u003c\/li\u003e\n  \u003cli\u003e118-degree split-style point angle for standard entry and reduced walking on flat surfaces\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length body reduces flex and deflection in short-hole drilling\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with all standard drill chucks and rotating equipment\u003c\/li\u003e\n  \u003cli\u003eGeneral purpose grade suitable for metal, wood, and composite materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard 3-jaw drill chucks and collet systems accepting a 29\/64-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the bit firmly in the chuck before operation and verify the chuck key is removed prior to powering the drill or press. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain cutting edge integrity.
