Diamond drill bits recommendations

 

SPEED TABLE IN REVOLUTIONS / MINUTE
To obtain maximum performance of diamond useful, it is essential to use the proper peripheral speed for each type of material.
This table shows the optimal speed (r.p.m.) which must work the diamond tool according to its diameter.
