Anti -impact design helps to prevent drills from broken or damaged in this case. Deep bite design: The deep bite design of the screw knife head makes it more in -depth with the screw head. This can reduce the possibility of head sliding and improve the overall work efficiency by providing stronger connections between the drill and screws. Anti -sliding sawtooth blade: Screw knife head has anti -ski sawtooth blades. This design helps to clamp the screws more effectively and reduce the possibility of sliding out of the screw head from the screw head during the operation. The design of mechanical principles: The design of the screw knife head takes into account the mechanical principle. This includes factors such as torque and impact force. The design aims to ensure that when the impact driver is connected with the screw head, some collision reaction force is absorbed by the torque, which helps prevent the knife head of the drill. Hardness 62hrc: The hardness of the drill head head is equal to or greater than 62HRC (Luo's Class). This high -hardness level indicates that the drill bit material has been optimized for durability and can withstand considerable wear and stress without deformation or damage. note: The words may be different in different batches, but it does not affect the use.
