erve dat alle knop bits wurde produsearre over-sized 0,5-1,0 mm, wat betsjut dat bygelyks in 36,0 mm bit op syn minst 36,5 mm is as nij.Dit wurdt dien fanwegen de snelle earste slijtage op knopbits.
It is wichtich om te beskôgje dat it boarre gat kin ferskille yn grutte fanwege boarbetingsten, boarjen
praktyk en grûnfoarming.
