The TOPWAY External Micrometer is an external measuring tool for metalworking and car repair, delivering precise, repeatable readings. That accuracy brings confidence when checking tolerances or setting up parts in a home workshop. Are hardened carbide anvils and a drop forged steel frame enough for professional-level reliability?
⚡ At a Glance
- • Measurement Precision: Hardened carbide anvils with 0.01mm graduation for consistent, low-wear readings
- • Best for: Home workshops, garages and mechanics needing accurate outside measurements up to 25mm
- • Not ideal for: Users who require digital readouts or internal measurement capability
Hardened carbide anvils and a ratcheting thimble enable repeatable 0-25mm measurements. Drop forged steel enamelled frame improves rigidity and includes a plastic storage case.
Repeatable accuracy - with hardened carbide anvils
Hardened carbide anvils provide a wear-resistant measuring surface and retain flatness under repeated contact. The 0.01mm graduation allows fine incremental readings for precise sizing.
Consistent contact surfaces reduce measurement drift, lowering rework on machined parts. Ideal for checking shaft diameters, bushings and finished components.
Durable frame - with drop forged steel enamelled frame
Drop forging aligns the metal grain for greater strength and resistance to deformation, while an enamel finish helps protect against corrosion and surface damage. The robust frame keeps the anvil and spindle alignment stable under typical workshop stresses.
Stable alignment maintains accuracy during repeated use and rough handling in a garage. Longevity of the tool reduces the need for frequent replacements.
Controlled thimble action - with ratcheting thimble, lock and ratchet stop
A ratcheting thimble applies a consistent measuring force to the spindle, preventing over-tightening and operator variability. The locking mechanism secures readings for easier reading and recording.
Consistent measuring force improves repeatability between different operators. Locking measurements makes it quicker to transfer readings to inspection records.
