The bit measures 1-1\/8 inches in diameter with a 1\/2-inch Weldon shank, allowing it to seat securely in standard 1\/2-inch chucks and holders without slipping under torque. Built from high speed steel (HSS) with a bright, uncoated finish, it delivers reliable general-purpose performance. The 118-degree standard point angle suits a broad range of common drilling tasks on production floors, job sites, and maintenance shops.\u003c\/p\u003e\n\u003cp\u003eThis Series R57 bit fits applications where a large-diameter hole is needed but chuck capacity is limited to 1\/2 inch. The reduced shank design bridges the gap between large hole size and smaller chuck capacity, making it practical for HVAC, plumbing, electrical, and mechanical contractors who need to bore through structural steel, angle iron, copper, aluminum, and similar materials. The 3-inch flute length supports drilling to a maximum depth of 3 inches, and the right-hand spiral flute efficiently clears chips from the cut zone during operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/8-inch cutting diameter with 1\/2-inch reduced Weldon shank for use in standard 1\/2-inch chucks\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling versatility\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with right-hand cut direction\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish; no coolant required for general use\u003c\/li\u003e\n  \u003cli\u003eThree flats on Weldon shank prevent bit rotation in the holder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/2-inch capacity drill chucks and Weldon-style tool holders.
