2. MARKETING OBJECTIVE

The Model DH 40MRY is an upgraded version of the current Model DH 40MR that features the capability of
drilling maximum 40-mm diameter holes into concrete and the use of SDS-max shank tools. The performance,
durability and operability are greatly improved. In addition, the vibration level of the Model DH 40MRY is low
enough to meet the requirements of the EU Physical Agents (Vibration) Directive that requires employers to take
action to reduce exposure of workers to vibration below the exposure limit values (enforced in July 2005).
The main specifications are as follows:
(1) Lowest vibration level in the class thanks to the dynamic damper with a leaf spring and the new vibration-
absorbing handle
(2) High drilling speed with low vibration and noise level
(3) Self-drilling (Good feeling)
(4) Constant speed with variable speed control
(5) Soft-touch grip for easier handling
(6) Variable lock mechanism for easy working-angle adjustment of chisels, etc.
