Built from cobalt high-speed steel with a FIREX coating, it handles abrasive materials and cast iron where standard HSS taps wear prematurely. The modified bottoming chamfer allows threading close to the bottom of a blind hole while still providing enough lead-in for reliable thread engagement. With 3 flutes and a Class 2B fit, this tap produces threads suited to standard fastener tolerances. Overall length is 2.125 inches, and the tapping depth reaches 0.827 inches. Shank diameter is 0.168 inches, and the drive square measures 0.131 inches. Thread direction is right-hand.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for machine tapping operations on CNC machining centers, knee mills, and drill presses equipped with a tapping head or rigid tapping cycle. It is well suited for production work in cast iron and abrasive materials where tool life is a priority. The straight-flute design works in both blind-hole and through-hole applications. The H2 and H3 thread limits provide flexibility for plated or close-tolerance assemblies. Typical users include machinist shops, maintenance departments, and production facilities requiring consistent 8-36 UNF thread quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSS construction with FIREX coating for extended tool life in abrasive materials and cast iron\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3-flute straight-flute geometry supports both blind-hole and through-hole threading\u003c\/li\u003e\n  \u003cli\u003eClass 2B fit with H2 and H3 thread limits for standard and close-tolerance assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand 8-36 UNF thread form at 36 threads per inch\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — compatible with flood coolant or cutting oil applied externally\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machine tapping of 8-36 UNF threads in blind-hole and through-hole applications in abrasive materials and cast iron.

Power down and secure the workpiece before tool changes. Use a cutting fluid or tapping oil appropriate for the workpiece material to reduce heat and improve thread finish.
