Weight & Balance: A 2lb (approximately 900g to 1kg) head weight offers a good balance of power for driving tasks and control for precision work, minimizing user fatigue during extended use.
Faces: Machinist hammers typically have a dual-face design:
Flat Face: Used for general striking, driving punches and chisels, and light assembly work. The striking faces are often finely machined and polished for accuracy.
Peen Face: This can be a ball-peen (rounded) for shaping metal and rounding off rivet edges, or a cross-peen (wedge-shaped, perpendicular to the handle) for shaping and aligning metal.

Key Features
Heat Treatment: The head is typically heat-treated and tempered to ensure durability and strength, which is essential for metalworking applications.
Handle Material: While the user asked about the head, it's worth noting that these heads are commonly fitted with handles made of hickory or ash wood (for vibration absorption) or modern materials like fiberglass (for durability and shock reduction).
Standards: Many professional-grade machinist hammers conform to specific standards, such as DIN 1041.
