DEDRA 07A011 threading tool

Threading die holder Dedra 210 mm for dies M3–M12, model 07A011, is a manual tool designed to hold round metric dies securely while cutting or repairing external threads on bolts, rods and similar parts. The 210 mm length provides a comfortable lever for controlled hand operation, and the holder is compatible with standard round dies in sizes M3 to M12. It is intended for use in workshops, maintenance and metalworking tasks where precise manual threading is required.

Advantages

This die holder provides a stable and ergonomic handle that improves control during manual threading operations. Its compatibility with a range of metric die sizes (M3–M12) makes it versatile for common external thread repairs and small-scale production tasks. The straightforward mechanical design ensures easy fitting and quick replacement of dies, while the 210 mm length balances reach and torque for effective hand use.

Suitable for

• Cutting or repairing external threads on bolts and rods (M3–M12)
• Workshop and maintenance tasks requiring manual threading
• Small-scale metalworking and DIY projects
• Situations where controlled hand tapping and alignment are important

Key specifications

• Overall length: 210 mm
• Compatible die sizes: metric M3 to M12
• Type: manual die holder for round dies
• Intended use: cutting and repairing external threads

How to use

Select a round die with the required thread size and secure it in the holder according to the holder's clamping mechanism. Align the die with the workpiece and begin turning the holder by hand, keeping the tool perpendicular to the axis of the bolt or rod to ensure straight threads. Apply steady, even pressure and reverse direction periodically to clear chips and prevent jamming. After threading, inspect the thread for correct form and clean both the die and the workpiece.

Usage recommendations

Use cutting oil or appropriate lubricant when threading to extend die life and produce a cleaner thread. For damaged or heavily rusted workpieces, prepare the surface and remove burrs before threading. Store the holder and dies in a dry place to prevent corrosion and check the clamping mechanism periodically for wear.
