Overview
The CRAFTSMAN CMMT98347 is a single hand hammer with an alloy steel handle, weighing 3 pounds. Its weight puts it well above a standard 16-ounce claw hammer, suited to striking punches, chisels or stakes rather than driving finish nails.
A one-piece alloy steel handle fuses head and handle into a single forged unit, which removes the loose-head failure point of wood or fiberglass handled hammers over time. At 3 pounds it sits in drilling-hammer territory, meant for delivering force to a struck tool rather than precision nail work.
- One-piece alloy steel handle
- 3 pound total weight
- Model CMMT98347
- Sold as a single hammer
Who it's for
Fits users who need striking force for chisels, punches or masonry stakes rather than a carpentry claw hammer. Not the right pick for finish carpentry or delicate tap work.
Strengths and trade-offs
Drawn from this product's published specifications.
- One-piece alloy steel build resists loosening
- 3 pound head delivers solid striking force
- Too heavy for delicate finish carpentry
- Single-item set, no included storage or extras
Performance notes
The forged alloy steel construction means the handle will not loosen from the head the way a wood handle can over years of striking. The 3 pound weight delivers meaningful force per swing at the cost of the control a lighter hammer offers for finer work.
