- Cut internal threads in drilled holes for fasteners, fittings, and mechanical assemblies.
- Use in mechanical engineering, metal fabrication, and maintenance work where controlled threading is required.
- Start the tap square to the hole to reduce risk of cross starting and uneven flank load.
- Process: manual driving or assisted driving depending on your holder and machine setup
- Use: thread cutting, re tapping, and thread cleaning depending on condition
Note For consistent results, deburr the entry and keep the cutting area clean during use.
How do you confirm that the thread system matches the mating part?
Match the designation on the tool to the drawing and the mating fastener or gauge. For inch and pipe threads, confirm thread family and fit class before you start machining.
What does the designation W (BS) 12 x 12 mean on this tool?
It defines the thread family and size that the tool is designed to produce or inspect. Use it only on matching parts and avoid mixing similar inch series.

What are common causes of poor thread quality?
Misalignment at the start, an incorrect pre hole, or insufficient lubrication can increase torque and damage flanks. Clean chips from the tool and verify setup rigidity.
Can you use this tool for reworking an existing thread?
You can often re tap or clean threads if the original form is correct and damage is limited. If threads are severely deformed, consider re machining or repair options instead.
