Not many people, besides professionals, pay attention to the drill–driver torque although this a factor ensuring appropriate adjustment of the screwing force to the material used, as well as to the length and thickness of the screw driven.
Most do–it–yourselfers selects a specific model or drill–driver or driver based on the price and basic parameters. The rated voltage, battery type and capacity, as well as additional functions are considered the most omportant. It is, however, the drill–driver torque which affects the quality, efficiency and safety of work most.
The significance of the drill–driver torque
The torque is the product of the arm length (this arm is the screw diameter radius) and the force at its end, expressed in Newton meters (Nm). The higher torque is set on the drill–driver, the longer and thicker screws we can screw into the material of increasing hardness.
The torque should be set depending on the intended work type. The torque can be controlled in various drill–driver models by a clutch, gear, transmission or force sensors. The number of torque settings in the drill–driver is decisive for its multi–purpose characteristics and the usability for work with any type of screws and materials.
Torque and work efficiency
Inappropriate torque may lead to screw going through the material, frequent breaking of screw heads, bit and torx socket breaking, i.e. damaging them in a way making it impossible to screw them out or even identify them.
The knowledge of the screw driving torque is necessary to ensure high work efficiency. The screw driving torque is the value which the drill–driver torque should be set based on.
Knowing the screw driving torque helps to avoid many problems. This information ensures also saving of time which would have to be spent on attempts at determining the correct way of screwing into a given surface.
Every DMX screw has a driving torque specified, determined in the course of examinations based on C24 wood. As this value is relatively low, the screws can be fixed also with drill–drivers offering lower force.
Drill–driver torque and screw driving torque
Proper drill–driver setting for a given screw prevents the assembled structure from damage and helps to retain its full aesthetic values. Selecting a given torque setting in a drill–driver, we should remember this should always be higher than the screw driving torque.
Please remember! Do not screw in with the drill–driver having power lower than the screw driving torque.
