Hammer Rockforce RF-CP7025 — 400 g locksmith/metalworking hammer

Rockforce RF-CP7025 — 400 g locksmith/metalworking hammer is a compact hand tool designed for controlled striking, shaping and fitting work on metal and related materials. With a 400 g head and a balanced profile, this hammer is intended for precise manual hammering, light forging and tasks where accuracy and reduced rebound are important. The tool is suitable for workshop use, sheet metal operations and assembly work that require measured blows and good tactile feedback.

Advantages

The hammer combines a moderate head weight with a compact design to provide controlled impact energy while minimising operator fatigue. Its balanced construction improves accuracy for shaping and fitting tasks, and the smaller head size allows access to tighter areas than heavier hammers. Materials and geometry are chosen to deliver predictable strikes and consistent performance during repeated use.

Suitable for

• Sheet metal forming and tapping
• Fine metal shaping and planishing
• Light forging and peening
• Assembly and fitting of metal parts
• Workshop repair and maintenance tasks requiring precise blows

Key specifications

• Head weight: 400 g
• Tool type: locksmith / metalworking hammer
• Design: compact, balanced head for controlled blows
• Primary use: striking, shaping and fitting metal components
• Typical applications: sheet metal work, assembly, light forging

How to use

Hold the hammer near the end of the handle for maximum control and use measured swings for precise strikes. Position workpieces securely in a vice or on a stable surface before hammering. Use the hammer head for light to moderate blows, increasing force only when required for shaping or fitting; avoid heavy overstrikes that could damage the workpiece or the tool. Inspect the striking faces and handle condition periodically and keep contact surfaces clean to ensure predictable performance.

Usage recommendations

For best results, pair the hammer with appropriate supports such as anvils, dollies or backing blocks matched to the task. Use personal protective equipment—gloves and eye protection—when working with metal. If greater force is needed, choose a heavier hammer rather than overstriking with this 400 g tool to avoid damage and reduce risk of tool or workpiece failure.
