Westward 1PZ45 Tap and Die Set 12 Piece

12-Piece UNF Tap and Die Set

This Westward 1PZ45 set contains twelve pieces designed for cutting Unified National Fine threads. It includes five taps and matching round fixed dies in sizes from 1/4 In. -28 up to 1/2 In. -20. The tools are made from High Speed Steel for durability in hand threading tasks. It suits mechanics and maintenance crews needing a compact UNF kit.

UNF Thread Standard Limits

The set covers only Unified National Fine pitch threads in the listed sizes. It cannot cut coarse UNC, metric or pipe threads. The round fixed dies require a compatible die stock for use and do not adjust for wear. Hand taps demand manual alignment and steady pressure to avoid breakage in harder materials. California Proposition 65 warnings apply to this product.

High Speed Steel Material Decides Suitability

High Speed Steel construction determines whether this kit matches the workpiece. It handles mild steel, aluminium and plastics but wears quickly in stainless or hardened alloys. Buyers who need to thread tougher metals or require adjustable dies should look elsewhere. The fixed die design also limits precision compared to split die alternatives.
