question your operators who cut the drums ramming the drill into not only damages the cutting tool, the threads in the drill stems and BLOWS the packing in the rotary head
we have had 3 failures in the last few years , it normally takes 3 -4 hours to change, it takes longer to get permits and scaffold built than to replace the packing cartriage
