(4) Protector
Although the previous model's hammer case designed for professional use is sturdy and well reputed, a
standard protector for the hammer case is desired to protect the surface of a workpiece such as flooring
materials from being scratched by the hammer case or the seats of set screws. The Models WH 12DM2/
WR 12DM2 are equipped with a protector having the following three functions:
It protects workpieces from scratches and stains.
Thanks to the protector, the Models WH 12DM2/WR 12DM2 minimize staining wall cloths or scratching
furniture and floor surfaces. As C's hammer case is unprotected and the aluminum base is exposed, black
marks may be remained if rubbed.
It is resistant to being caught on bracing plates etc.
It does not get hot even if operated continuously.
The hammer case of the Models WH 12DM2/WR 12DM2 does not get hot because it is covered with the
protector entirely.
The protector is made of elastomer having high heat resistance, and it does not impair the integrated looking
of the Models WH 12DM2/WR 12DM2.
The protector is standard. Comparison of stains
