Dies cut, clean and restore existing external threads to bolts, rods and conduit. Dies are standard workshop equipment for cutting accurate threads or for fixing damaged threads without having to replace the fastener.
A quality crimping die or crimping die set allows for better control over consistent thread shape and cleaner engagement during installation. Whether used for electrical fittings, conduit or general workshop use, the right die allows threading to be a more controlled and predictable process.
Dies are common tools for trade and workshop applications for tasks ranging from fabrication to maintenance where clean threads are needed.
Dies are most often used to cut new threads or to restore damaged ones. Dies are appropriate for bolts, threaded rod, conduit fittings, and other hardware where damaged or flattened threads can prevent parts from tightening completely. In many instances, simply running a die over the thread is enough to clean up the thread and make the part functional again.
Split dies are useful when slight adjustment is needed during threading. Solid dies are more rigid and better suited to consistent production work.
On electrical and workshop jobs, dies are often used alongside copper hand tools, cable cutters & strippers, and hand snips when preparing fittings, conduit, and threaded hardware.
The material and thread type both affect how the die performs.
Carbon steel dies suit lighter work and occasional use. High-speed steel options are stronger and better suited to harder materials like stainless steel or regular workshop use.
Thread pitch also matters. Matching the die correctly helps avoid damaged threads and poor fitment.
A few things help improve cutting performance:
Correct thread pitch selection
Proper lubrication during cutting
Steady alignment when starting
Clearing swarf regularly
Using the correct die stock
Split dies allow slight adjustment to thread fit, while standard hex dies suit many common die holders and compact threading setups.
Clean setup and steady pressure make a big difference when threading.
Start the die square to the material
Use cutting lubricant where needed
Clear metal shavings regularly
Avoid forcing the cut
Clean dies after use
Cross-threading usually happens when the die starts unevenly or too aggressively. Taking the time to align the die properly helps produce a cleaner thread and reduces wear on the cutting edges.
After use, removing swarf and applying light oil helps protect the die and keep the cutting edges working properly.

Helpful advice from knowledgeable staff
With the right setup, thread cutting becomes cleaner, easier, and more reliable.
A tap is used to cut internal threads. A die is used to cut external threads.
HSS dies are appropriate for harder materials and more frequent use.
Pitch is often measured with thread gauges or a sample bolt with the same pitch.
Split dies can be slightly adjusted to alter the fit of threads or the cutting pressure.
Lubrication is highly advised when cutting stainless steel.
A few of the dies can be used for threading conduit, depending on material and die style.
Improper alignment or inconsistent starting pressure is the most common cause of this issue.
Yes, minor thread damage can be cleaned up with the proper die.
