• To extend the life of the crown and obtain a better finish, it is recommended to use grinders with a speed regulator.
• The larger the crown, the higher rpm the grinder should have.
• To drill, it is recommended to start with an attack angle of 30º-45º and carry out oscillating movements to make the most of the bit and reduce localized wear and overheating.
• Once the drilling is finished, the grinder must be stopped without removing it from the hole and wait until the crown has completely stopped before moving the grinder, to avoid accidents with the remains of the drilling. Once the grinder has stopped, the remaining material must be removed from the crown.
