Shorter set-up times and less downtime reduce process costs, which increases productivity. In addition, in the event of wear, it is not necessary to replace the entire drill but only the drill heads, which reduces the tooling costs. Another advantage is the possibility of regrinding, which extends the tool life and avoids expensive new purchases.
