The Revolution drill is engineered to drill solid materials without the need for a pilot hole by using an over-center cutting geometry for the indexable carbide inserts and the single, adjustable cartridge. This cartridge, which is designed to be removable for fast and easy replacement, allows the diameter to be adjusted to 5.1 mm, thereby permitting a hole-size range of 1.875" (47.63 mm) to 4.0" (101.60 mm).
