WIPO Patent Application WO/2021/241737
Kind Code:
A1
Abstract:
Provided is a work machine with improved operatability. In a cutting tool 10, a guard member 70 that is made of metal is provided inside a chip discharge passage section 64, and a bottom wall of the chip discharge passage section 64 on a saw blade 12 side is covered by the guard member 70. In other words, a bottom surface of the chip discharge passage section 64 is guarded by the guard member 70 that is made of metal. Accordingly, the guard member 70 can prevent high-temperature metal chips from coming into direct contact with the bottom wall of the chip discharge passage section 64. Thus, deformation of the chip discharge passage section 64 when chips pass through the chip discharge passage section 64 can be suppressed. Consequently, the durability of a saw cover 60 can be increased, and the operatability of the cutting tool 10 can be improved.
