Further improvements have been made to the next generation of Seco's exchangeable crown drills - Crownloc Plus. A proven geometry design of the crowns together, with a strong locking interface and wide polished flutes, gives the possibilities to drill various materials with an excellent chip evacuation and wear resistance. Moreover, it requires no regrinding or resetting.
The new range is extended with 8xD drill bodies and multiple diameters in the range from 12.0 to 19.90 millimetres.
