BTR/BOR spot weld drill bit set (81432155740)
This drill bit set is designed specifically for releasing spot-welded joints of hard and extremely hard steels. The corners and flanks are equipped with a radius so that the cutters are less likely to become stuck on the outside. This has a positive effect on the overall service life.
Spot weld cutters are suitable for spot weld loosener Vario Drill pneum.
It is recommended to always work with cutting oil or other suitable cutting additives. Hard steels means that the cutting edges of the tools can become very hot. With the appropriate cutting additive, they extend the service life many times over.
