Torque is delivered by all cordless screwdrivers, but only a few include torque control. An adjustable clutch is another name for torque control. When inserting screws, torque control allows you to set the degree of torque required for the work at hand. The chuck and torque screwdriver work bit stops spinning when that level is achieved, avoiding too much torque from being transmitted at once.
High-volume production and the manufacture of very sensitive items such as satellites or internal medical equipment both require the capacity to manage the torque. Small variations in the torque applied to each screw may result in considerable percentages of the product being lost in high-volume production. The failure of a single screw in a highly sensitive device might have disastrous consequences. As a result, torque screwdrivers are used by enterprises across a wide range of sectors to manufacture their goods safely, successfully, and economically.
How does torque control work?
The cordless screwdriver will experience resistance when driving in screws, making it more difficult to drive the screw in. To overcome this resistance & drive the screw to the precise depth, enough torque must be applied. If you use too much force, the screw may be pushed in too far or you may lose control of the screwdriver, damaging the work surface or screw head. With the torque control ring, you may select a maximum amount of torque for your work ahead of time.
The clutch will disconnect the tool’s driveshaft and stop the screwdriver bit from rotating once that level is achieved. The motor within continues to move, but the chuck & screwdriver bit have come to a halt, preventing the screw from being pushed any farther in. If the screw isn’t entirely pushed in when the screwdriver stops, you’ll need more torque. Release the speed control trigger, remove the screwdriver away from the screw, and adjust the torque level as needed. The torque control ring is used for this.
Can you feel torque control kick in?
Yes, in most cases. The drive shaft will ‘click’ when the ideal torque is reached. You’ll frequently hear this and feel the tool’shudder’ as a result. The motor is spinning, but the chuck and bit are still immobile. It’s possible to drive the screw too deep into the material or lose control of the screwdriver if you don’t use torque control.
What about models without torque control?
Torque is still delivered by cordless screwdrivers without torque control, but the torque ring is not adjustable. Instead, the speed control trigger is used to increase and reduce the torque level. The screwdriver will travel quicker if you pull the trigger deeper, but it will generate less torque. The screwdriver will run slower when you release the trigger, but it will generate greater torque.
Which Torque Screwdriver Is Best for Your Business?
Torque screwdrivers come in a variety of styles, but they may be divided into three groups according to their motor power: manual, electric, and pneumatic. The best one for your company is determined by the unique requirements of your product. Desired production rate, needed torque output and specificity, documentation requirements, your manufacturing environment, and the diameter of the screws you’ll be dealing with are all elements that might affect your decision.
