The Stanley SK47 Sinker Drill is primarily designed for blast hole drilling and can drill up to 2" (50mm) in diameter and up to 10ft (3m) deep. The sinker drill uses air to flush the holes clear of debris reducing drag on the drill bit.
The air flow is automatically shut off when the trigger is released. The Stanley SK47 hydraulic sinker drill features a feathering trigger for easy starts and adjustable rotation from 0-300rpm.
