2, cladding has good insulation performance, and therefore the accident of electric aspect can not take place.

3, the hand-held tool that produces by the present invention, because cladding is main framework, cladding has characteristics such as high strength, high rigidity, lightweight, thereby make the intensity height, in light weight of hand-held tool, and cladding after pressurized, heated with expose matrix bond and be integral, the position of hand-held tool interlock workpiece still is made of the matrix that exposes of metal material, so still do not lose the wear-resisting toughness of metal material itself, keep the basic purposes and the function of hand-held tool, significantly improve the intensity of whole hand-held tool, strengthened durability.

4, cladding has acidproof alkali, corrosion resistance, and its skin can not get rusty, and running into sour alkali environment can destroyed surface yet.

5, cladding has good thermal insulation, can not conducted by heat easily because being in high-temperature work environment, and it is still comfortable to guarantee that hand grips.

6, cladding has better elastic, and the vibration force that in operating process hand is generated can be retarded, and appropriate shock-absorbing is provided, and makes hand gripping sense of touch preferable.

7, cladding can add colorant and make its changes colour if adopt glass fibre, allows the form diversification more of hand-held tool, perhaps can be on cladding the printing color pictorial trademark.
