As an alternative to use the preparation kit tools handheld (for the coring, the planning and recess routing) the CN829 DSV-Kit can be used, ensuring the three steps are performed as specified.

The kit includes a suction plate with adjustable pliers and a vacuum pump.

For testing the suction plate is connected to the vacuum pump. Pressing the suction plate against the concrete surface will activate the vacuum. The two blue adjustable pliers are secured to the suction plate.

First, the center coring is performed with the flange of the diamond drill unit clamped to the suction plate, followed by surface planning using the Diamond Planner, also clamped to the suction plate.

Finally, the recess routing is performed in the correct 25 mm depth with the router flange circumference following the inner circumference of the suction plate.
