WESTport's Popular Special Metric Dies provide manufacturers with a fast, dependable solution for producing precision external metric threads when standard catalog tooling is not enough. Designed for machine shops, OEMs, maintenance departments, repair facilities, and production manufacturers, these dies cover many of the most commonly requested non-standard metric sizes and pitches while offering the flexibility of complete custom manufacturing. WESTport maintains one of the industry's largest inventories of tap and die blanks, allowing for exceptionally fast turnaround on custom special dies manufactured directly from your blueprint or sample.
Every WESTport Popular Special Metric Die is manufactured using premium High-Speed Steel (HSS) and other high-performance tool steels selected to provide exceptional wear resistance, dimensional stability, and long service life. Precision grinding produces accurate thread geometry, sharp cutting edges, and excellent surface finishes that consistently produce high-quality external metric threads. Whether your application requires standard ISO metric threads, modified pitches, oversized or undersized tolerances, left-hand threads, or another custom configuration, WESTport can manufacture tooling to your exact specifications.
Metric threads are used extensively throughout today's global manufacturing industries, making reliable thread-cutting tools essential for maintaining productivity and quality.
