Built from high speed steel with a bright uncoated finish, it measures 5\/8 inch (0.6250 inch) in diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration for easier penetration and reduced walking on entry. The straight-cylindrical shank and two-flute spiral design provide consistent chip evacuation during through-hole and blind-hole drilling operations. Licensed tradespeople and maintenance machinists reach for this bit when working through steel, cast iron, stainless steel, non-ferrous metals, and other hard materials.\u003c\/p\u003e\u003cp\u003eThis bit fits standard drilling applications across industrial, commercial, and field-service environments. With an overall length of 7.125 inches and a flute length of 5.1875 inches, it handles drilling depths up to 5-3\/16 inches, making it suitable for structural steel fabrication, mechanical assembly, and maintenance repair work. It belongs to the Series R10P-R15P-R18P family and conforms to ANSI standards. The right-hand cut geometry is compatible with conventional drill press and handheld power drill operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for durability across steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry force and improved centering\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes efficient chip clearance during drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (0.6250 inch diameter) seats securely in standard keyed or keyless chucks\u003c\/li\u003e\n\u003cli\u003e7.125-inch overall length with 5.1875-inch maximum drilling depth suits most jobber-length applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains dimensional accuracy and simplifies regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit conforming to ANSI standards, suitable for use in standard 5\/8-inch capacity drill chucks on drill presses, magnetic drills, and handheld power drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tradesperson familiar with rotary cutting tool safety.
