Tap and Die Set ROCKFORCE 76pcs M3–M12 model 1100710

ROCKFORCE 76-piece tap and die set covers metric thread sizes M3 to M12 and is designed for cutting, repairing and maintaining internal and external threads on metal components. The kit contains a variety of taps, dies and accessories to handle common workshop, automotive and maintenance tasks that require thread creation or restoration within the specified metric range. The set is supplied in an organized case for storage and transport and is intended for use with standard hand tools or compatible tapping and die-holding fixtures.

Advantages

The set provides a wide size range from M3 to M12 in a compact, portable case, allowing quick selection of the correct tool for each thread size. Hardened cutting tools deliver wear resistance for repeated use on steel and common metals. Included holders and wrenching tools simplify alignment and control when cutting or restoring threads, reducing the risk of cross-threading. The organized layout in the case keeps components secure and easy to inventory.

How to use

Select the correct tap or die corresponding to the thread size required. For internal threads, secure the workpiece, center the tap in the hole, and apply cutting oil to reduce friction. Turn the tap slowly and evenly, backing off periodically to clear chips. For external threads, mount the workpiece in a vise if possible, fit the appropriate die into the die holder, align carefully and cut while applying cutting oil, using gradual passes until the full thread depth is achieved. After cutting, clean chips and inspect threads for proper form and fit with mating parts.

Usage recommendations

Use appropriate cutting fluid and steady, aligned pressure to prolong tool life and improve thread quality. Start with pilot holes of recommended diameters for each metric thread size, and avoid excessive force to prevent tap breakage. Store the set dry and clean after use to prevent corrosion and maintain cutting performance.
