ALETO Stainless Steel Dial Bore Gauge belongs to workshop measurement tools designed to capture internal dimensions precisely. Clear readings and robust construction ease the frustration of repeated checks for engineers and machinists. Does the kit suit routine engine-bore work and hold up in a busy shop?

⚡ At a Glance
  • Measuring Accuracy: 0.01mm resolution with a clear 56mm dial for precise comparative readings
  • Best for: Engineers and machinists measuring inner hole sizes and engine cylinders
  • Not ideal for: Applications requiring digital output or finer-than-0.01mm resolution

Measures internal sizes across a 50–160mm range using the comparative method. Metal-cased dial and a guiding protective bridge support repeatable readings.


Highly precise readings – with a 0.01mm resolution dial

Dial gauge reads to 0.01mm and uses a 56mm face for clear graduations; the comparative method records deviation from a reference setting. Metal dial construction reduces wear on the scale and keeps markings legible.

Fine graduations let users detect small bore variations reliably, ideal when checking cylinder wear or honing results. Faster, confident decisions follow from clear, repeatable measurements.

Repeatable centring and clamping – thanks to a guiding protective bridge and eccentric locking

A self-centring protective bridge aligns the measuring anvils automatically while anti-slip surfaces help maintain position; an eccentric locking mechanism secures the assembly during reading. Comparative measuring requires a stable reference and steady contact for consistency.

Consistent alignment reduces measurement scatter between readings, so successive checks on the same bore match closely. That saves time when confirming tolerances across multiple cylinders.

Durable build and organised storage – with metal dial casing and supplied box

Metal-lined dial housing improves wear resistance and extends service life, while the kit ships with a storage box sized to hold components securely. Materials and packing limit abrasion and accidental loss during transport.

Longer component life and an included case make the kit workshop-ready and portable. Parts stay protected between jobs and are less likely to be misplaced.
