6 Pcs 1/4-20 UNC Thread Tap Set, M2 HSS Right Hand Thread Milling Tap

Key features

• Industrial Titanium Coating – Boosts heat resistance and wear resistance even in non‑ferrous and plastic materials, reducing tap wear
• Through‑Hole Chip Flow – Straight flutes enable chips to drop downward and exit freely – no chip reversal needed
• HRC 67 Hardness – Quenched HSS 6542 maintains edge sharpness for repetitive soft material tapping
• Full‑Ground Finish – Precision‑Straight flutes reduce friction and promote chip clearance for cleaner threads
• Right‑Hand UNC Tap – Standard rotation for manual and CNC through‑hole tapping operations
• 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 6-piece 1/4-20 UNC thread tap set is made from quenched HSS 6542 with industrial-grade titanium coating. The coating significantly improves heat and wear resistance, extending tool life even in repetitive metal threading. Designed for downward chip evacuation, the fully ground precision process creates a super smooth surface that allows chips to flow freely without clogging. Hardness reaches HRC 67, ensuring clean threads in aluminum, mild steel, and other common metals. Class 2B tolerance guarantees consistent fit for standard fasteners.
