Available coating variants

High-Speed-Steel – for drilling boreholes into well- processed materials with strength of up to 900 N/mm²

High-Speed-Steel – with 5% content of cobalt – for drilling boreholes into difficult processing materials with strength of up to 1100 N/mm²

Titanium-nitride coating – high hardness – low coefficient of friction – extended service life

Titanium-aluminium-nitride coating – for dry cutting – a ceramic surface provides the friction minimization – optimum service lives – highest cutting speed rates
