Ground from high speed steel with a bright uncoated finish, it features a standard 118-degree split point, two spiral flutes with a regular helix, and a straight cylindrical shank. The web is thinned and tapered for improved chip clearance and reduced thrust during drilling. Overall length is 1.375 inches. This bit is part of the R18P series and is built for general-purpose drilling in production and maintenance environments handled by machinists, tool and die technicians, and skilled tradespeople.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The 0.0330-inch diameter makes it appropriate for small-diameter through-holes, pilot holes, and precision tapping prep work. Flute length is 0.500 inches, providing a maximum drilling depth of 0.500 inches. The straight cylindrical shank seats directly in standard drill chucks and collet holders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 66 — decimal diameter 0.0330 inches for precision small-bore drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — ready for use as-ground, compatible with cutting fluids\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes with regular helix promote efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eANSI-standard geometry for consistent fitment across compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard drill chucks and collet systems accepting a 0.0330-inch straight cylindrical shank.
