SDS-plus chisel
HERMAN MH-23 Hollow+
Hollow for gutters

High-strength and specially heat-treated tool steel:
for high durability and tool life

Side protrusions of the working part:
minimize edge tearing when chopping - the gutter is clean, with precise lines

Recommendation:
- for chopping into concrete, we recommend using hammers with an impact energy of at least 3J
- when working, regularly lubricate the chisel shank (preferably every 20 minutes) with a suitable lubricating grease. This will prevent overheating and extend the life of the machine
- at least approximately maintain the geometry of the angles of the working part of the chisel by regular sharpening. You will achieve consistently high work productivity with less effort for the machine and the operator

Warning:
During chopping and demolition work, the working temperature of the chisels reaches high values - often 200 degrees Celsius or more. Therefore, be careful when replacing chisels or lubricating their shanks.
