2. Inherent Drawbacks of Cordless Driver Drills Requiring
Particular Attention during Sales Promotion
The cordless driver drill offers many advantages; it can be used in places where no power source is
available, the absence of a cord allows easy use, etc. However, any cordless tool has certain inherent
drawbacks.
Salespersons must be thoroughly familiar with these drawbacks in order to properly advise the customer in
the most efficient use of the tool.
A. Suggestions and precautions on efficient use of the tool
(1) Use the cordless driver drill for comparatively light work.
The motor output of battery driven cordless driver drills is rather low compared with conventional electric
power tools. Accordingly, they are not suitable for the continuous drilling of many holes in succession, or
for drilling into particularly hard material that imposes a heavy load. Salespersons should recommend
conventional electric power tools for such heavy work.
(2) Work requiring particularly strong torque should be conducted at low speed.
Instruct the customer to conduct work that requires particularly strong torque at low speed, as locking of
the motor may occur at high speed.
