Compare Fretz raising and embossing hammers to find the right tool for your metal forming projects, with key trade-offs and fit guidance.
Quick answer
Choose the Fretz HMR-305 Large Raising Hammer for broad outside shaping and angle raising, and the Fretz HMR-109 Rounded Wide Raising/Embossing Hammer for stretching metal from the inside to form bowls and concave shapes.
Raising vs. embossing: different metal movement
The main difference between raising and embossing hammers is where the metal is worked from. Raising hammers like the HMR-305 compress metal from the outside of a broad shape, while embossing hammers like the HMR-109 stretch metal from the inside. This determines the shape you can create and the finish you get.
Trade-offs to consider
The HMR-305 moves metal quickly and leaves a relatively smooth surface, but its broad face may not be precise for detailed work. The HMR-109 has a wide, longer profile ideal for blocking bowls and wider strips, but it requires working from the inside and may need more finishing.
How to decide: raising vs. embossing hammer
- Start with the shape: If you are forming a bowl or concave shape, choose the HMR-109 embossing hammer to stretch metal from the inside. For broad outside shaping, such as angle raising, choose the HMR-305 raising hammer. Match the hammer to the direction of metal movement you need.
- Consider the finish: The HMR-305 leaves a relatively smooth surface, which can save time on finishing. The HMR-109 may require more planishing or smoothing after forming. If you value a smoother finish, the HMR-305 is the better choice.
- Think about speed: The HMR-305 moves metal quickly due to its broad face, making it efficient for large pieces. The HMR-109 is more suited for controlled stretching of specific areas. For rapid metal movement, choose the HMR-305.
Product facts
- Rounded Wide Raising/Embossing Hammer, Fretz HMR-109: The wide and longer profile of this hammer marks it ideal to block bowls and broader width strips into concave shapes. As with all embossing hammers, this hammer is intended to stretch the metal from the inside. Use the HMR-109 when you need to form concave shapes from the inside, such as bowls or wide strips.
Rounded Wide Raising/Embossing Hammer, Fretz HMR-109 - Large Raising Hammer, Fretz HMR-305: The HMR-305 is a broad faced raising hammer that moves the metal quickly when the metal is hammered from the outside of a broad shape. The metal is compressed down to the stake and is left in a relatively smooth condition when compared to bowls or hollowware that is raised with a narrow crosspien. The HMR-305 is efficient for raising broad shapes from the outside, leaving a smoother surface and reducing finishing work.
