Fretz® Double Ended Insert Hammer

Form, raise, emboss, and planish precious metals without thinning sheet or leaving hammer marks on finished surfaces. The Fretz® HMR-7 Double Ended Insert Hammer combines cast stainless steel construction with an ergonomic Padauk hardwood handle. Designed for non-marring metal forming, the HMR-7 features two modular locking collars that hold any combination of its nine (9) specialized Delrin plastic inserts. The interchangeable inserts replicate the profiles of traditional planishing, embossing, and raising hammers, allowing jewelers and silversmiths to move and true metal securely without stretching or thinning the material.

Why Choose the Fretz® HMR-7 Double Ended Insert Hammer

• 9 Interchangeable Non-Marring Delrin Inserts: Duplicates the working geometries of planishing, doming, and raising hammers:

  • Planishing Inserts (Flat & Domed): Smooths metal surfaces and trues ring shanks over steel mandrels without leaving strike facets.

  • Embossing Inserts (Spherical & Bullet Taper): Domes metal from the inside out and raises repoussé volumes without thinning the sheet.

  • Raising Inserts (Rectangular & Chisel Cross-Peen): Compresses cylinders and forms curves against stakes without marring polished stock.

• Dual Modular Locking Collars: Both ends feature precision stainless steel collars equipped with hex-socket set screws, allowing quick insert swaps using the included hex wrench.

• Moves Metal Without Thinning: High-density Delrin plastic transfers the hammer's kinetic energy to shape and bend metal while preventing the thinning and distortion caused by steel-on-metal blows.

• Balanced Weight: Provides the necessary mass and striking momentum to move metal decisively with minimal effort.

• Ergonomic Padauk Hardwood Handle (220 mm): Features a contoured pistol-style grip that flexes naturally to absorb recoil and reduce wrist fatigue during repetitive forming.
