Overview
A job site that needs a short, heavy striking tool suits this Estwing drilling hammer, built from alloy steel in both head and handle and finished in blue and yellow. The grip is a cushion style.
The reason to buy is a one-piece steel build from a brand that backs its all steel hammers against failure. The limit is that the warranty text spells out strike types it will not cover.
Who it's for
Workers who strike punches, stakes or chisels with a short, heavy tool. The cushion grip softens shock. Carpenters who frame or pull nails should buy a claw hammer instead.
Pros and cons
- Alloy steel throughout
- Flat striking face
- Warranty excludes misuse strikes
- No claw for pulling nails
- Head weight single option
Performance notes
A short handle gives control and less swing arc, while a steel head delivers concentrated force through the flat face. Cushioning in the grip absorbs part of the shock. Misuse such as striking other hardened tools can damage a steel head.
