A “good” penetration rate for core drilling is 0.2 - 0.5 m/min, depending on formation. Experience with Wassara precollaring in solid rock in mineral exploration is 0.8 - 1.2 m/min, but very much depending on rock formation, bit quality and skill of the operator.

You can probably drill approx. 5 times faster with Wassara compared with core drilling, but this cannot be guaranteed.
