Combination Tapping Die M10 x 58 mm 1/4" – Siemens

Combination tapping die M10 x 58 mm (1/4") by Siemens is a metal die intended for cutting or repairing external metric threads. Designed to produce M10 threads with a working length of 58 mm, the tool is compatible with standard die holders and tapping tools used in maintenance, mechanical assembly and repair tasks where accurate external threading of rods, studs or shafts is required.

Advantages

The solid metal construction provides dimensional stability and wear resistance for repeated use. Its combination design allows simultaneous cutting and sizing of threads, reducing the need for multiple operations. The die is compatible with common die holders, facilitating quick installation and interchangeability in workshop settings.

Suitable for

• Repairing damaged external M10 threads on bolts, studs and rods
• Producing new M10 external threads during mechanical assembly
• Maintenance work in industrial and workshop environments
• Applications requiring metric M10 threads with a 58 mm engagement length

Key specifications

• Thread size: M10
• Working length: 58 mm
• Thread form: metric external thread
• Material: metal die (suitable for cutting metal threads)
• Compatibility: for use with standard die holders and compatible tapping tools

How to use

Secure the combination tapping die in a matching die holder and align it with the workpiece. Apply cutting lubricant suitable for the material being threaded. Rotate the die evenly and apply steady pressure to start the thread, reversing periodically to clear chips if allowed by the die holder design. Continue until the required engagement length is reached, then back off the die and clean the new threads. Follow general workshop safety practices, including eye protection and appropriate hand tools.

Usage recommendations

For best results, use a cutting lubricant appropriate to the workpiece material, maintain correct alignment to prevent cross-threading, and inspect threads after cutting for dimensional accuracy. Replace the die if signs of wear or damage appear to ensure consistent thread quality.
