Product information "Diamond Hollow Drill Bit Connection "A""
Ideally used for enlarging existing bores. A factor to be considered is, that this diamond hollow drill bit does not dispose of an ejection needle. If necessary, the drilling core must be expulsed manually. Also, inner cooling is recommended. Preferrably, with water quenching. However, you will achieve better results with one of our drilling systems.
Our diamond hollow drill bit is completely interspersed with diamonds. The Drill bit is grinded between peaks. This production procedure of grinding effects a less abrasion of the Drill bit common with high rotation.
Our hollow drill bits are available in different shank connections, different wall thickness, as well as special order models.
