What is the impact of cutter head hardness on manual flat head screwdrivers
As a traditional tool, the manual flat-blade screwdriver plays an important role in various repair and assembly tasks. As one of the key characteristics of a manual flat-blade screwdriver, the hardness of the blade has an important impact on its performance and service life.Wear resistance
The hardness of the blade directly affects the wear resistance of the manual flat screwdriver. Higher hardness bits can better resist wear and extend the life of the tool. During long-term use, if the hardness of the blade is insufficient, the blade may easily become dull or wear too quickly, affecting the tightening effect of the screw and even damaging the screw head.
Resistance to deformation
The high-hardness cutter head is more resistant to deformation and can maintain shape stability under larger torque. When tightening screws with larger diameters or harder materials, if the hardness of the cutter head is insufficient, the cutter head may easily deform, causing the screwdriver to fail to fit the screw slot correctly, or even causing damage to the screw head.
Torque transmission efficiency
The hardness of the cutter head also has an important influence on the efficiency of torque transmission. Proper tip hardness ensures that the screwdriver can effectively transmit torque to the screw to tighten or loosen the screw. If the tip is not stiff enough, it can result in inefficient torque transfer, requiring more force to do the same job.
Damaged screw head
Insufficient hardness of the blade may cause damage to the screw head. When the hardness of the cutter head is lower than that of the screw head, it is easy for the cutter head to slip or the blade edge to slip out of the screw groove, causing wear or deformation of the screw head. This not only affects the service life of the screw, but may also cause the screw to fail to be tightened or loosened normally.
