Features

The Hilti DD 30-W is equipped with a number of innovative features that make it the fastest, most accurate, and most user-friendly core drill in its class. These features include:

TopSpin technology: This exclusive technology accelerates the drilling process by up to 300% by slightly eccentrically rotating the core bit. This results in more effective transfer of pressure to the diamond ring, which allows the bit to cut through material more quickly.
Soft-start feature: This feature helps to prevent the core bit from wandering by gradually increasing the motor speed over a period of two seconds. This ensures that holes are drilled perfectly straight, even in difficult materials.
Built-in laser guide: This guide helps to ensure that holes are drilled perfectly straight by projecting a laser beam onto the work surface. This is especially helpful when drilling in difficult-to-see areas or when drilling multiple holes in a row.
Lightweight design: The DD 30-W is only 3.9 kg (8.6 lbs), making it one of the lightest core drills on the market. This makes it easy to maneuver and use for extended periods of time.
Ergonomic handle: The DD 30-W's ergonomic handle provides a comfortable grip and reduces operator fatigue.
