Metric Oversize Taps

Metric Oversize Taps are designed for metric threads in holes that require extra clearance and robust cutting action. This collection highlights precision tapping tools built for oversize applications, offering dependable performance, durable steel construction, and consistent thread quality across multiple tolerances. They are suitable for a variety of materials, including aluminum, steel, and cast iron, and are engineered for long life under heavy use in workshop or shop-floor environments.

Within this collection you’ll find metric oversize tapping options ranging from small M3x0.5 up to larger M16x2, with tolerances such as +0.005, +0.010, and +0.015 to suit precise fit and finish. Spiral-point taps are included for fast, clean thread formation and positive plunger action, while conventional taps provide general-purpose performance. All tools are engineered for repeated use in demanding workshop environments, with durable finishes and precision-ground threads to ensure consistent results across many jobs.
