What are the advantages of core drilling over twist drilling?
Antwort:
Core drilling is an exceptionally economical drilling method:
Faster, quieter, and more precise than twist drilling. Without pre-drilling or retooling, it reduces your working time by up to 40%. And you can significantly reduce the cost per hole compared to conventional methods.
In contrast to twist drilling, core drilling only machined a narrow ring rather than the entire drilled surface. This requires significantly less feed force. This protects the user, the core drill, and the machine, as it operates with significantly lower electrical power. After the material has been penetrated, the drill core is automatically ejected by the combined centering and ejection pin. Both overlapping holes, e.g., for slotted holes, and offset holes are possible.
