Models
MARKETING OBJECTIVE
The new Models DH 25DL, DH 25DAL, DH 36DL and DH 36DAL are developed under the same concept as the
well-reputed Models DH 24DV and DH 24DVA. These new models are more lightweight and their working
capacities are higher than the current models thanks to the adoption of the lightweight and high-voltage lithium-
ion batteries. Features of the Models DH 25DL, DH 25DAL, DH 36DL and DH 36DAL include the following:
(1) Lightweight and compact
(2) Large number of holes can be drilled per battery charge.
(3) Fastest drilling speed in the class
(4) Switchable hammering force mechanism
(5) New lithium-ion batteries 25.2 V/36 V (Slide-in/out type)
We aim to expand the market share of our cordless products by introducing these new Models DH 25DL,
DH 25DAL, DH 36DL and DH 36DAL.
APPLICATIONS
• Drilling anchor holes
• Drilling holes in concrete, tile, brick, and similar materials
• Drilling holes in steel and wood
• Tightening and loosening machine screws and wood screws
