Tools for Pounding and Hammering

Sledge Hammers. Sledge hammers have heads forged from heat-treated high carbon steel; they weigh from 3.6 to 9 kg (8 to 20 lb).

Driving sledges are used to set heavy timbers and drive heavy spikes or hardened nails. Stone sledges are used to break boulders or concrete. Because of differences in tempering, these tools are not interchangeable.

Hand-Drilling Hammers. Hand-drilling hammers are used to drill steel into rock or to drive wedges and feathers into cracks or drilled holes. There are two types of hand-drilling hammers—single jacks and double jacks. For more information on hand drilling, read Hand Drilling and Breaking Rock (1984).
