Tap and Die Set MEGA 24-piece (model 67224) — taps and dies for threading

MEGA 24-piece tap and die set (model 67224) provides a comprehensive selection of taps and dies for cutting and repairing metric threads. The kit includes a variety of metric sizes designed to create or restore internal and external threads on rods, bolts and fittings. Designed for workshop and maintenance tasks, the set is suitable for metalworking, automotive repairs and general DIY threading operations where reliable, repeatable thread cutting is required.

Advantages

The set groups commonly used metric taps and dies in one compact, organized case, reducing the time needed to find the right tool. Hardened steel components provide abrasion resistance and maintain cutting geometry over multiple uses. Ergonomic handles and holders improve control during tapping and die-cutting, while the included case protects tools from corrosion and simplifies storage. The set supports both repair and production tasks by covering a range of internal and external thread sizes.

Suitable for

• Cutting new metric internal threads in tapped holes
• Restoring damaged or worn threads on bolts, studs and fittings
• Creating external threads on rods and shafts
• Workshop maintenance, automotive repair and equipment servicing

Key specifications

• Contents: 24 pieces including a selection of metric taps and matching dies and holders
• Material: hardened and heat-treated steel suitable for cutting common ferrous materials
• Thread standard: metric thread profiles
• Storage: compact protective case for organized transport and storage
• Tool types included: hand taps, round dies and holders for manual thread cutting

How to use

Select the correct tap or die size for the desired thread pitch and diameter. When tapping a hole, drill the correct size pilot hole first, secure the workpiece, apply cutting fluid to reduce friction, and start the tap square to the hole. Turn the tap forward a few turns, then back it off to break chips and prevent jamming. When cutting external threads with a die, mount the workpiece securely in a vise, fit the die into the holder, apply cutting fluid to the workpiece, and rotate the die evenly while keeping it aligned to the rod axis. Clean chips from the tool periodically and inspect threads for correct form.

Usage recommendations

Use appropriate cutting fluid for the material being worked to extend tool life and improve thread quality. Do not force taps or dies; back off regularly to clear chips. For hardened or stainless steels, consider incremental cutting steps and use taps and dies rated for tougher materials. Store the tools dry and clean to avoid corrosion and preserve cutting performance.
