Three flutes countersinks
ANTI VIBRATIONS
90° Angle
Red'X coating
3 flatted shanks
The equal division 3 x 120° of the flutes offers good results in most materials.
For iron alloys vibrations may happen and generate facets.
These new ANTI VIBRATION countersinks with unequal division of the flutes avoid this phenomenon.
HSS-E Cobalt + Red'X = hardness 65 HRC, to machine steels up to 1000 N/mm², Cast irons up to 200 HB, copper, brass, bronze, aluminium. The Red'X coating = hardness 3500 HV considerably increases the tool life for intensive use, by increasing wear resistance and improving surface finish.
