5/8"-11 UNC Thread Tap Set, M2 HSS Right Hand Thread Milling Tap

Key features

• Industrial‑Grade Titanium Coating – Provides superior heat resistance and wear resistance for heavy‑duty through‑hole threading in structural steel
• Through‑Hole Design – Straight flutes direct chips downward to exit completely – no chip packing in thick plates
• HRC 67 Hardness – Quenched HSS 6542 maintains cutting edge strength under high‑torque through‑hole tapping
• Precision Full‑Ground Flutes – Straight flutes surfaces reduce friction and enable fast chip clearance for clean 5/8″‑11 threads
• Class 2B Tolerance – Guarantees reliable thread fit for construction, heavy machinery, and structural assembly through holes
• Ultrasonically welded outer shell creates a permanent seal; any opening attempt leaves irreversible traces, ensuring brand-new products. The inner storage case prevents metal-on-metal friction during transit, protecting cutting edges and coating, and serves as permanent organizer by size. This dual design combines tamper-evident security with a reusable case that lasts the drill bits' entire life

This single 5/8″‑11 UNC straight flute tap is manufactured from HSS 6542 with a heavy‑duty industrial‑grade titanium coating. Designed for through hole tapping in structural steel, thick steel plates, and heavy fabrication components. The straight flute geometry allows chips to travel downward and exit the hole freely – critical for thick plates where chip removal must be unimpeded. Full‑form precision grinding delivers a polished flute surface for rapid chip evacuation under high torque. Quenched to HRC 67 hardness. Class 2B tolerance ensures proper thread fit for structural bolting
