Size rings, smooth hammer marks, and true precious metal shanks with a single versatile bench tool. The Fretz® HMR-6 Planishing Hammer pairs a hardened stainless steel head with an oil-finished Padauk hardwood handle, combining traditional steel planishing with modern non-marring forming. Engineered primarily for bench jewelers who size rings and want an all-in-one hammer solution, the HMR-6 features a slightly domed 19 mm polished steel face on one side and a flat 19 mm replaceable plastic (Delrin) insert on the other. Secured with a hex-socket set screw, the flat plastic tip forms metal while keeping surfaces smooth and scratch-free, while the opposite steel face provides solid metal-on-metal energy transfer for truing shanks and light planishing.
Why Choose the Fretz® HMR-6 Planishing Hammer with Insert
-
Dual-Action Workstation Efficiency: Combines two essential bench tools—a steel planishing hammer and a non-marring mallet—into a single, agile 220 mm tool.
-
Flat Non-Marring Plastic Face (19 mm): Delivers clean striking force to reshape bands, size rings on steel mandrels, and adjust wirework without stretching metal thin or leaving dents.
-
Replaceable Insert Assembly: The plastic tip mounts firmly in a stainless steel collar and locks via a side hex screw, allowing quick replacement or maintenance using a standard hex key.
-
Slightly Domed Polished Steel Face (19 mm): The mirror-polished steel end is slightly domed to strike flat and subtly curved metal without digging sharp edges into the workpiece.
-
Precision Hardened Stainless Steel Head: Resists pitting and rust, transferring energy directly to the work without flaking or dulling.
-
Ergonomic Padauk Hardwood Handle (220 mm): Features a contoured neck that flexes naturally to absorb shock, dampen vibration, and reduce repetitive wrist strain during long sizing sessions.
