Manufactured from high speed steel with a bright uncoated finish, it measures 0.1990 inches in diameter with an overall length of 3.625 inches and a flute length of 2.4375 inches. The 118-degree standard point angle suits everyday production and maintenance drilling. A tapered web with web-thinning reduces thrust during entry and improves chip clearance. This bit is sized and built for use by machinists, maintenance technicians, pipefitters, and metalworking trades requiring a reliable, straight-cylindrical shank bit in the 0.150 to 0.200 inch size range.\u003c\/p\u003e\n\u003cp\u003eThe 46078 fits standard drill chucks and is well-suited for repetitive hole-making in light to medium steel plate, structural steel, pipe, and similar metal stock encountered in fabrication shops, mechanical rooms, and field service. The fast spiral flute promotes efficient chip evacuation in through-hole and blind-hole applications. Right-hand cutting direction is compatible with conventional drill press, handheld power drill, and CNC spindle setups. No coolant-through capability is required or supported, making it a straightforward fit for dry or flood-coolant surface-applied operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 8 with 0.1990 inch decimal diameter and diameter tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for general-purpose drilling in steel workpieces\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eFast spiral, 2-flute design promotes chip evacuation in metalworking applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for dry cutting or surface-applied coolant use\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1990 inches diameter fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock drill bit for applications requiring a wire gauge size 8, 0.1990 inch jobber length bit with a straight-cylindrical shank in the 0.150 to 0.200 inch size range per Series 150B specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance mechanics, or trade professionals using standard drill press or handheld power drill equipment. Secure the straight-cylindrical shank fully in the chuck and verify runout before drilling. Power down and de-energize all equipment before changing bits.
