Micrometer Set M304.425 (150–300 mm) — ratchet stop, blue powder-coated

The Micrometer Set M304.425 is a six-piece mechanical micrometer set for external measurements of medium-format components, designed for machine shops, tool rooms and inspection benches.

• Six-piece set, 150–300 mm coverage
• Ratchet stop for consistent measuring force
• Hardened measuring faces for durability
• Blue powder-coated frame with matt chrome drum

Reliable workshop performance from robust construction

This six-piece set offers a continuous measuring range from 150–300 mm by combining individual instruments in 25 mm steps and includes calibrated setting standards (150 / 175 / 200 / 225 / 250 / 275 mm) for quick verification. The instruments are analog mechanical micrometers built to DIN 863, with a spindle diameter of 6.5 mm and a spindle pitch of 0.5 mm, providing a familiar mechanical feel and predictable lead per revolution. The ratchet stop reduces operator variability by limiting applied measuring force, which helps maintain reproducibility when the same dimension must be checked repeatedly in production or incoming‑inspection.

Precision where it matters — clear readout and hardened faces

With a reading resolution of 0.01 mm, the set supports typical shop and inspection tolerances while keeping the measuring process straightforward. The measuring faces are hardened, resisting wear and maintaining measurement integrity even after frequent contact with workpieces. The matt‑chrome measuring drum provides a low‑reflection surface for easier reading under bright workshop lighting, and the painted frame resists minor impacts and corrosion. These features together reduce the need for premature replacement and keep measurement uncertainty low in daily use.

Practical handling and transport advantages

Each instrument includes a ratchet stop and ergonomic frame geometry to support comfortable, single‑hand operation when measuring medium‑sized components. The set is supplied as a six-piece set, packed in a transport case for secure storage and mobility between bench and machine. The blue powder‑coated frame offers visual identification in a busy workshop and adds an extra layer of surface protection. The combination of robust spindle construction and secure storage reduces downtime and simplifies logistics for small to medium production runs.

Application guidance and suitability

This set is suited for component inspection, gauge checks and workshop setups where a measuring range of 150–300 mm is required. Conformance to DIN 863 ensures compatibility with common workshop practices and inspection plans. The included setting standards enable quick verification of zero and intermediate checks without external calibration equipment. For operations that demand frequent repeat measurements and stable force application, the ratchet mechanism is a clear operational advantage that improves measurement consistency across operators.
