This fluteless machine tap is intended for chipless internal thread forming in a machine controlled process. You use it when the workpiece material can be plastically formed and when a formed thread is preferred for process cleanliness and repeatability. The product name already defines the metric thread, tolerance class, and tool style for selection.
The M designation identifies metric ISO threads that are standard across general engineering, maintenance, and machine building. HSSE or HSS-E indicates cobalt alloyed high speed steel, which supports hot hardness and wear resistance under more demanding cutting conditions. Form C in this context identifies a tool geometry aligned to the stated tapping application and hole condition. An oil groove supports lubricant supply into the forming zone during the threading process.
Note Confirm thread designation, holder concept, and workpiece condition before you start the operation.
Match the thread designation, standard, and execution from the product name to the drawing or the existing mating thread before you start the job.
How do you decide whether the product fits your process?Check whether you need manual handling, assisted driving, or a controlled machine process, and confirm that the product type in the name matches that use case.
What should you inspect before the threading operation?Inspect hole or workpiece condition, alignment, lubrication plan, and holder suitability so the tool can work under controlled conditions.

Can you use this product for repair work as well as new threads?In many workshop situations, yes, provided the tool type, thread condition, and workpiece state support that use case.
Where can you find the full threading tools catalog? What is the main selection checkpoint after size matching?After size matching, the main checkpoint is whether the tool form and process type suit the workpiece material and the intended hole or external thread condition.
