Technical Characteristics of Power Tools

The products of Bosch Power Tools B.V. are developed and produced according to high quality standards and in accordance with the generally accepted rules of technology. The technical data and functions of our products are regularly checked during development and in series production by application of statistical methods. Through this, we ensure that the products meet our quality standards and the expectations of the users as far as possible.

It is normal, however, that the actual performance of a power tool varies from device to device. The specific application of a tool and environmental conditions have a significant influence. The respective technical information, e.g. on packaging and in manuals, refers to average values and applies to the products and their accessories when new. Below you can find an exemplary overview of the most important influencing factors on the actual performance of a power tool with respect to its application and the environmental conditions.

TYPICAL ICONS AND VALUES
may differ depending on the model

Battery runtime

Battery runtime
Typical icons and values (may differ depending on the model)

The battery runtime of our cordless tools depends on several influencing factors such as, e.g.

  • the externally applied load profile, which depends on
    • material properties of the work piece (for example height and density of grass, density of wood, …)
    • dimensions of the work piece (for example volume of tires, diameter and length of screws, …)
    • work techniques and working speed (for example the force applied by the operator)

Longest runtime can be typically achieved under no-load conditions.

  • ambient temperature – optimal battery performance can be reached in the range of 15-25°C. At low temperatures, the available runtime and power of a battery is reduced.
  • status of battery: the capacity of a battery strongly depends on its lifetime history, for example the age, number of charging cycles, type of charging (fast/slow), charging levels (always to “empty”, or even into deep discharge condition may reduce the battery capacity over time).

 

Charging Time

Charging time
Typical icons and values (may differ depending on the model)

The charging time of our batteries depends on several influencing factors such as, e.g. …

  • battery state of charge before charging starts
  • ambient temperature
  • status of the battery: capacity (declines over the battery lifetime), as well as its charging history, for example the number of charging cycles, type of charging (fast, slow), charging levels (always to “empty”, or even into deep discharge condition may reduce the battery capacity over time).

 

Sawing, Routing, Cutting performance

Sawing, Routing, Cutting performance
Typical icons and values (may differ depending on the model)

The sawing, routing and cutting performance of our power tools depends on several influencing factors such as, e.g. …

  • type, quality & status of accessory (selection of appropriate blade, bit,…)
  • externally applied load profile, which depends on material properties of the work piece (e.g. hardness and density), dimensions of the accessory, cutting depth etc.
  • well fixed workpiece / machine – e.g. no vibration with jig saw work
  • lubrication in some applications
  • work techniques, e.g.
    • force that is applied by the operator
    • the grain direction of wood in relation to the direction of cut
  • battery type and state of charge

Sanding, Grinding, Planing performance

The sanding, grinding and planning performance of our power tools depends on several influencing factors such as, e.g. …

  • The type, quality & status of an accessory (type of sanding paper, grain size, blade type, bit type,…)
  • ·externally applied load profile, which depends on material properties of the work piece (e.g. dimensions, hardness, density, humidity, grain direction of wood, …), the size of the working surface, etc.
  • work techniques, e.g.
    • force that is applied by the operator
    • fixation of workpiece and machine – to avoid vibrations
  • battery type and state of charge

Speed (rpm) – no load speed

The rotational speed of our power tools is indicated as a maximum value under no-load conditions that is not exceeded in order to avoid accidents with unsuitable accessories. It depends on several influencing factors such as, e.g. …

  • status of the tool, such as its run-in status and its temperature, which influences the battery performance and the viscosity of internal lubrication
  • electrical input voltage & current, battery state of charge
  • load that is induced by the dimensions and mass of the accessory

Noise and Vibration

Noise and Vibration
Typical icons and values (may differ depending on the model)

Vibration level and noise emission values are measured in accordance with a standardized measuring procedure, e.g. EN 62841‑2‑11.

The stated vibration level and noise emission values represent the main applications of the power tool. However, if the power tool is used for other applications, with different or worn-out accessories or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period.

Electrical input power

Electrical input power
Typical icons and values (may differ depending on the model)

The electrical input power of our power tools mainly depends on the electrical input voltage & current from the operator’s power supply network.

Luminous power

The luminous power of our lamps depends on several influencing factors such as, e.g. …

  • battery state of charge
  • maintenance status of the lamp (well cleaned screens)

Gluing capacity

Gluing capacity
Typical icons and values (may differ depending on the model)

The gluing capacity of our glue guns depends on several influencing factors such as, e.g. …

  • use of correct glue stick: material properties and dimensions of glue
  • status of nozzle (clean)
  • force applied by user
  • battery type and state of charge

Heat-up time / ready-to work in x seconds

The heat up time of our glue guns mainly depends the ambient temperature and the initial temperature of the glue gun.

Airflow temperature of heat guns

The airflow temperature of heat guns mainly depends on the working distance between nozzle and work piece. The warm-up cycle needs to be completed for optimal results.
