Milwaukee CU Crimping Die Kit, 16–300mm² Copper Cable Crimp Dies in Organised Case

This kit includes eight dies that cover copper conductor sizes from 16 mm² up to 300 mm². It comes in a purpose-built plastic storage box with a detachable lid for easy transport and organization. The dies are steel for durability and each die features a 12-point opening for reliable crimping.

It’s designed to work with the Milwaukee R22 ratchet crimper and is also compatible with most other brands’ hand ratchet crimpers that use 12-point dies.

Key specs include eight dies ranging from 16 mm² to 300 mm², steel construction for long life, a compact carry case for storage and transport, and 12-point die openings for secure, consistent crimps.

Open or release the crimping tool, remove the current die, insert the desired die from the kit ensuring it seats fully, and lock it in place. Then place the copper conductor in line with the die, operate the tool to crimp, and inspect the result. Repeat with the appropriate die for each job.

The dies cover copper conductor cross-sections from 16 mm² up to 300 mm², enabling a wide range of electrical and plumbing-related crimps with copper tubing.

Use them for crimping copper conductors in electrical installations, service panels, and HVAC/plumbing projects where secure, code-compliant connections are required.

After use, wipe clean to remove debris and moisture, lightly oil moving parts if recommended by the tool manufacturer, and store the dies in their carry-case slots to prevent misplacement and corrosion.

Yes. Always wear eye protection and gloves, work on a stable surface, keep hands clear of the crimping jaws during operation, and ensure the conductors and tools are in good condition before use.

Yes. Getting eight dies plus a carry case in one kit can be more cost-effective and convenient than purchasing each die individually, especially when you need a broad range of sizes for multi-project work.

Yes. To replace a die: (1) Unock or open the crimping tool, (2) remove the current die from the die holder, (3) insert the new die from the kit so it seats fully, (4) ensure the die is locked in place, and (5) proceed with crimping on the appropriate conductor size.

Check that the die is fully seated and locked, verify the conductor size matches the die opening (16–300 mm² range), perform a test crimp on a scrap piece, and inspect for a clean, centered bite with no gaps or over-crimping. If results vary, re-check die seating and alignment before continuing.
