Block - This vice parallel block is easy to install and provides solid support for machinist blocks. Milling machine vice - Robust and durable, not easy to break; prevents corrosion and surface rust; finish is not easy to paint; designed for use with machine blocks. Block - Smooth surface and polished finish; neat and generous in profile, smooth to the touch to reduce the risk of hand injury during handling. Material - Made of low-tension steel, resistant to deformation; precision ground and hardened for accuracy and long life. Use scenarios - Secure and align small workpieces during milling, drilling, or finishing operations to ensure consistent parallelism. - Serve as a reference block in setup to check squareness and alignment on a milling machine or fixture. - In a workshop, fixture fixtures and clamp components for repetitive machining tasks, improving efficiency and repeatability.
