Fretz® Narrow Raising Hammer

Raise small-scale hollow forms, compress tight cylinders, shape concave curves, and execute precise forging on precious metals. The Fretz® HMR-3 Medium Narrow Raising Hammer pairs high-grade cast, hardened stainless steel with an ergonomic, oil-finished Padauk hardwood handle. Engineered with thinner cross-peen heads than traditional raising hammers, its dual rectangular faces—20 mm x 6 mm and 20 mm x 5 mm—fit easily into narrow radiuses and deep concave channels where broader hammer faces cannot reach without hitting adjacent walls.

Why Choose the Fretz® HMR-3 Narrow Raising Hammer

• Dual-End Ultra-Slim Raising Faces:

  • 20 mm × 6 mm Face: Delivers concentrated cross-peen force for raising small cylindrical tubes, spout contours, and tight concave shapes.

  • 20 mm × 5 mm Face: Features an even slimmer profile to navigate deep recesses, sharp internal radiuses, and intricate anticlastic channels.

• Non-Gouging Radiused Edges: Both faces are ground with smooth, rounded corners that prevent gouging, cutting, or sharp edge-line indentations on silver, gold, copper, or brass.

• Precision Forging & Planishing Utility: Serves as a versatile dual-purpose tool—concentrating blow force to forge wire and bar stock lengthways, or lightly planishing tight concave areas smooth over miniature stakes.

• Mirror-Polished Stainless Steel Head: Hardened stainless steel head resists rust, pitting, and denting, ensuring smooth metal-to-metal energy transfer without imparting surface blemishes.

• Ergonomic Padauk Wood Handle (220 mm): Slender neck flexes naturally to absorb shock, deliver crisp tactile rebound, and minimize wrist strain during prolonged raising courses.
