The bit features a 118-degree standard point angle and a steam oxide finish that provides a measure of lubricity and corrosion resistance during operation. With a 1\/16 inch diameter and an overall length of 1.875 inches, this is a small-diameter bit suited for precision holes in tight locations. The regular spiral flute and tapered web configuration promote efficient chip evacuation, and the web-thinned tip reduces the thrust required to start the cut. Licensed tradespeople and maintenance professionals working in HVAC, plumbing, and electrical applications install this type of bit routinely.\u003c\/p\u003e\u003cp\u003eThe 5997500 is built for general-purpose production and maintenance drilling. It performs in steel and cast iron workpieces and is appropriate for use in both shop and field settings. The straight shank fits standard drill chucks without adapters. The Series R10A-R15A-R18A designation identifies the product family within the PRECISION TWIST DRILL lineup. The 7\/8 inch flute length supports drilling up to 0.875 inches deep before chip packing becomes a concern, making this bit practical for thin stock, sheet metal, and enclosure work common in trade service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eHSS construction with steam oxide finish for added lubricity and surface protection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tip with tapered web reduces cutting thrust on small-diameter entry\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 14xD flute-to-diameter ratio for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards and NAS 907 specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in steel, cast iron, and similar workpiece materials conforming to material codes P, M, K, N, and S per the Series R10A-R15A-R18A product family.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a standard drill chuck and verify the shank is fully seated and the chuck is tightened before drilling.
