Specification Size: Total length * rod diameter * rod length * PH value of the cutter head
Trivia 2:What does the PH value of the bit indicate? A: PH indicates the sharpness of the batch head tip, the smaller the value means the more sharp the tip. Such as: PH1 head than PH2 more pointed PH0 than PH00 more pointed, the opposite value PH2 head than PH1 head to flat. Home big electrical appliance screws to PH2 mainly! Precision instruments PH0/PH00 is the main!
Material: S2 steel
Trivia 1: the higher the hardness of the batch head the better? A: A good screwdriver head should be made of S2 material, and the hardness of the screwdriver head is controlled by heat treatment, the harder the screwdriver head hardness is not the harder the more durable, too high hardness is easy to collapse the angle, too low hardness is easy to slip the wire The internationally recognized stable hardness is at HRC60t
