Compact soil and backfill with this Pneumatic 40-lb. Tamper with 6" Butt (T022292) from Chicago Pneumatic. Designed for light to medium applications, it's capable of slow, powerful blows to efficiently and quickly compact all types of backfill, including clay and soils containing high percentages of finely crushed or powdered material. The heat-treated cylinder and chrome plated piston significantly extends tool life, while the exhaust deflector directs air, moisture and oil away from the operator.
