drillable
Able to bore
Drillable describes materials or surfaces that can be penetrated by a drill without excessive difficulty or damage.
In oil and gas contexts, drillable refers to geological formations suitable for drilling operations.
The term also appears in dentistry and construction, where knowing whether something is drillable determines tool selection and technique.
The concrete was drillable once it had fully cured.
