The hammer manufacturer said that for a claw hammer, the thickness of the handle will be different. The thicker one can make the handle and the claw hammer head more stable. Protection of human hands.
For the hammer head, it is generally made of steel. During processing, the steel needs to be heated and forged. Usually it takes several forgings to fully form. After the forging, because there are many paths, it needs to be deburred and polished. . After the polishing is completed, induction hardening is done on the working surface to improve the local strength. The handle will have different materials, mainly wood, and plastic. For the wood, it must be dried first, and then turned into the desired shape. You can use a hydraulic press to press the handle into the hammer head, and then press the wedge into the joint to increase the bonding fastness.
If it is a tool hammer, it is basically a combination of hammer handle and hammer head. In fact, it can only be used as a percussion tool, and more attention should be paid when using it.
