M 48x1.5- Tap - Robust 2X-VA - TIN
Frontal recess (bell-shaped chip collector) for receiving the chip material in blind hole threads.
Increased profile clearance angle reduces friction and thus the inclination to cold pressure welds.
Preferably to be used with paste lubrication!
Specially designed large size tapping with a cutting crown for excellent self-guidance when beginning to cut.
