The TASKMASTER TM6500 Grinder

The effective and economical TASKMASTER TM6500 compact grinder is equipped with hardened, alloy steel cutters and tungsten carbide seal faces for high performance with a small footprint.


With CUTTER CARTRIDGE® technology, individual cutter and individual spacer disks  are combined into high strength, one piece elements. This design eliminates weak individual cutter and spacer disks, greatly increasing unit strength. With CUTTER CARTRIDGE® technology, there’s no stack retightening required, no shaft scoring problems and no catastrophic stack collapse – problems found with other units.

The TM6500 is provided standard for 4” (100mm) pipe sizes. Other configurations can be provided for 6” (150mm) pipe sizes as well as open channels.
