SDS-plus Chisel
HERMAN MH-20 Hollow
Hollow for grooves in concrete and masonry

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

Recommendation:
When working, regularly lubricate the chisel shank (preferably every 20mins) with suitable grease. This will prevent overheating and prolong the life of the machine
Maintain at least approximately the geometry of the angles of the working part of the chisel by regular sharpening. You will thus achieve consistently high work productivity with less effort for both machine and operator

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