Tap and Die Set Rockforce RF-M076-3 — 76 pieces, metric M3–M12

Rockforce RF-M076-3 — 76 pieces, metric M3–M12 is a comprehensive tap and die set designed for cutting, repairing and restoring metric threads on bolts, rods and housings. The kit includes a range of hand taps, round dies, tap wrench, die stock, and common accessories to cover internal and external thread work from M3 up to M12. It is intended for general mechanical maintenance, fabrication and repair tasks where metric threads are required.

Advantages

The set provides a wide selection of metric sizes in a single organized case, reducing the need to source individual tools for common thread repairs. Tools are arranged for quick identification and access, supporting efficient workflow in workshop and field environments. Compatibility with standard metric threads makes the set useful for both professional technicians and hobbyists performing maintenance on machinery, vehicles and assemblies.

Suitable for

• Repairing damaged internal threads in housings and engine components
• Cutting new external threads on rods and bolts
• Restoring stripped threads on fasteners during maintenance
• Small fabrication and assembly work requiring M3–M12 metric threads

Key specifications

• Number of pieces: 76
• Thread range: metric M3 to M12
• Includes: selection of hand taps, round dies, tap wrench and die stock
• Storage: fitted carrying case for tool organization
• Intended use: manual cutting and repair of internal and external metric threads

How to use

Select the tap or die matching the required metric thread size (M3–M12). For internal threads, secure the workpiece, apply cutting lubricant and start the tap perpendicular to the hole, turning gradually and reversing occasionally to clear chips. For external threads, mount the appropriate round die in the die stock, align with the rod or bolt and turn progressively while using lubricant to ensure even cutting. Use the provided tap wrench and die stock for manual control and maintain steady, even pressure to avoid cross-threading. Inspect threads after cutting and remove burrs or debris before assembly.

Usage recommendations

For consistent results use appropriate cutting lubricant, support thin-walled workpieces during threading, and choose the correct tap or die size for the intended fit; when repairing heavily damaged threads consider pre-drilling or using thread inserts as required by the application.
