With its newly developed shank generation, this is the first thread former that can not only be used conventionally on CNC machining centres and lathes, but also for the first time offers the advantages of thread forming over thread cutting for use on box column and pillar drills (up to dia. M12).
- One tool for through hole and blind hole threads
- No chipping issues due to cold forming of threads
- Thread depths up to 4xD can be achieved
- Improved thread surface quality
- Higher strength in the thread
- Significantly longer service life
- Completely reliable threads
Newly developed shank generation with a combination of polygonal and straight shank (from dia. M4-M12)
The polygonal shank prevents spinning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage.
Newly developed tool geometry for versatile use in almost all materials
TiN coating
The coating, which is the most popular coating on thread formers due to its universal application area, ensures a very long service life and reduced friction values.
New lubrication groove geometry
The optimised lubrication grooves (from dia. M3) significantly improve the lubrication effect in the contact area.
X allowance for longer service life and increased process reliability
Available exclusively from Würth
Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable
- Caution: A special predrilling diameter larger than in thread cutting and with tighter tolerances is required for thread forming! The suitable core hole diameter is stored as a technical characteristic for all thread formers.
- In thread forming, the main job of the cooling lubricant is lubrication. The more lubrication used with the highest possible grease content, the longer the service life. The lubrication also affects the surface quality of the thread! For water-mixed cooling lubricants, we recommend an oil concentration in the emulsion of at least 8% for steel processing and at least 12% for stainless steel processing. We recommend Würth cutting paste Cut and Cool Perfect for use on free-standing/pillar drills.
- Please note that for thread forming, you will need approx. two times as much performance (torque) compared to thread tapping. The means that capacity should be considered when using thread-cutting devices.
