How long or how many drill holes does a core drill last?
Answer:
Dependent on many influencing factors such as speed, feed force, material to be drilled, condition of the core drill, use of coolant.
FEIN HM ULTRA: Maximum service life of the core drill 400 holes = 8 m total service life (determined under optimum conditions (Ø18 mm, S235 20 mm)
FEIN HSS NOVA: Maximum service life of the core drill 140 holes = 2.80 m total service life (determined under optimum conditions (Ø18 mm, S235 20 mm)
