Built to NAS 907 Type J standards, this bit features a 135-degree split point that reduces walking and cutting pressure at the start of each hole. The M42 cobalt steel construction and gold oxide coating provide heat resistance and extended tool life compared to standard HSS bits. At 1.417 inches overall length with a straight-cylindrical shank, the C70058 suits standard drill chucks and driver collets used in production and repair environments. Machinists, pipefitters, and fabricators working with aluminum and similar materials will find this bit suited to both hand-held and machine-mounted drilling operations.\u003c\/p\u003e\u003cp\u003eThe C70058 is intended for drilling aluminum and other non-ferrous metals in light fabrication, HVAC equipment assembly, plumbing fixture work, and general trade shop use. The 1.1 mm diameter (0.0433 inches decimal equivalent) makes it appropriate for pilot holes, tap prep, and small-diameter through-holes. The regular spiral flute and tapered web configuration promote efficient chip evacuation during continuous drilling. This bit sells individually but requires a minimum order quantity of 12 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and durability in metal drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers thrust force at entry\u003c\/li\u003e\n\u003cli\u003eGold oxide coating improves lubricity and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered, web-thinned design for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for dimensional and material consistency\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight-cylindrical shank fits standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length drill bit for use in standard drill chucks and machine spindles accepting a straight-cylindrical shank with a 0.0430-inch shank diameter.
