Diagram Reference: E‑21

🧰 What It Is

The Punch Hammer is a core impact‑producing component inside the rotary hammer’s pneumatic hammer mechanism. In rotary hammers, the hammer piston (sometimes called the punch hammer) moves rapidly back and forth in a cylinder to generate percussive force. This force is what drives the drill bit into hard materials like concrete, brick, and stone.

⚙️ Technical Function

The punch hammer performs several essential roles:

1. Impact Generation

  • Converts the rotary motion from the crankshaft/geartrain into linear hammering motion inside the cylinder.

  • As it moves forward in the cylinder, it compresses air and delivers a powerful impact blow to the mechanism that transmits force to the drill bit.

2. Energy Transfer & Compression

  • Works inside the pneumatic chamber (cylinder) with precise clearance.

  • The air compression ahead of the punch hammer produces the high‑energy impacts that make rotary hammers effective on masonry.

3. Reciprocating Motion

  • A connecting linkage (crank, connecting rod) drives the punch hammer back and forth hundreds or thousands of times per minute.

  • Efficient sealing and fit are needed for maximum impact force.

🛠️ Where It Fits

  • The E‑21 reference indicates its exact position in the exploded parts diagram of the RH150028.

  • It is mounted inside the cylinder (impact chamber), guided by seals and rings, and driven by the crankshaft or connecting rod mechanism.

  • It interfaces with springs, rings, and other internal components that help return it and maintain motion.
