Built to M42 cobalt steel with a titanium nitride (TiN) coating, it delivers extended tool life and heat resistance under demanding production and maintenance conditions. The 135-degree split point reduces walking on entry and lowers thrust requirements, making it well-suited for hand-held and drill-press work on harder alloys. Licensed contractors, machinists, and industrial maintenance technicians are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use on stainless steel and carbon steel workpieces, where cobalt-grade tooling is standard practice. The TiN coating adds surface hardness and lubricity, reducing friction and built-up edge during repeated cuts. The right-hand spiral flute with regular helix clears chips efficiently in both through-hole and blind-hole applications. It is a practical choice for HVAC, mechanical, and fabrication shops that routinely drill into stainless enclosures, brackets, hangers, and structural steel. The bit conforms to DIN 338 and NAS 907 Type J standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for high heat resistance in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends edge life and reduces friction on repeated passes\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for fast, self-centering starts with reduced thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design improves chip clearance and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with 2-flute regular spiral for reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for heavy-duty industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty jobber-length drill bit for use on stainless steel and steel workpieces; suitable for drill presses and hand-held electric drills accepting a 0.1990-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this bit in a keyed or keyless chuck that accommodates a straight shank of 0.1990 inches. Use appropriate cutting fluid or coolant when drilling stainless steel to prevent work hardening and extend bit life; this bit does not support coolant-through delivery. Ensure the workpiece is securely clamped before drilling.
