Knives for TERSA arbores and cutter heads
In the past it was problematic to produce profiled centrifugal locking knives (for ex. for Tersa
shaft) in high quality steel because it is too tough for moulding. In conjunction with the world
leader in Tri-Metall-steel strip production we solved this problem by the development of the
new generation of TriHSS® M42 knives. The principle: the steel strip is welded in a
sandwich-technology. The centre part of the planer blade consists of soft and therefore
good malleable steel and the two cutting edges, in response to demands for longer life, are
produced from high quality Tri-HSS m42 steel. Like all BARKE® – knives these new ones also
have the additional counter grind. The advantages:
better shavings ejection, greater sharpness, breakage safety and longer edge life.

Comparison of results of HSS-M2 and HSS-M42
- TersoTri® -TRITALL® HSS-M 42 are produced of better 24,9 % TriHSS®-steel quality –
it is about 10% higher analysis quality, compared with Original Tersa-Knives („M 2“ with
only 18,5 %-Analysis).
- TriTALL® TriHSS® - M42 last 75% longer compared with Original Tersa-Knives M2
