Description
Product Overview
The Peacock CC-3A Dial Bore Gauge Set covers the 50–150mm range in a single kit, giving you a direct-reading internal measurement solution that’s genuinely useful across a wide spread of toolroom and production work. Built around a Peacock dial indicator and a full complement of interchangeable extension rods, this set lets you measure bores, cylinders, and housings quickly and accurately — without the faff of indirect measurement and arithmetic. It’s the kind of kit that earns a permanent spot on the bench.
- 50–150mm measuring range with interchangeable extension rods — The labelled rod tray covers sizes from 50mm through to 100mm in 5mm increments, plus three small-increment extensions numbered 1–3. That spread means a single setup handles everything from small hydraulic cylinder bores to large spindle housings, reducing the need for multiple gauges on the same job.
- Peacock dial indicator with 0.01mm graduation — Reading to ten microns (roughly 0.4 thou) is sufficient for the vast majority of fitting, boring, and honing work. The large dial face gives a clear reading without squinting, and the Peacock movement is known for consistent, repeatable needle return — critical when you’re checking taper or out-of-round across multiple positions in a bore.
- Centralising cone mechanism for consistent gauge alignment — The rocking-type centring design automatically finds the true diameter of the bore rather than a chord, which is what separates a proper bore gauge from a fudged-up indicator arm. Consistent centring means your readings are repeatable between operators and between setups.
- Knurled handle grip and 50–150mm labelled stem — The handle is long enough to reach deep bores without losing feel, and the clearly stamped CC-3C / 50–150mm range marking on the barrel saves any guesswork when pulling the tool off the shelf mid-job.
- Ideal for — checking cylinder bore wear and taper on engine rebuilds, verifying reamed or bored holes to tolerance before assembly, measuring housing bores for bearing fits, checking four-jaw or collet chuck concentricity, and confirming internal grind dimensions against a ring gauge or master setting ring.
Condition
(Used — Like New / Full kit, minimal use, excellent mechanical condition)
Mechanically, this set presents very well. The dial indicator needle returns crisply with no sluggishness or sticking, and there’s no observable backlash or play in the gauge body. The measuring anvils and contact points show no visible wear flats or pitting. The extension rods are all present, correctly seated in their labelled tray positions, and free of the dings or raised burrs that would affect accuracy. The handle knurling is sharp and the stem slides smoothly. Cosmetically, the case shows the light surface scuffs you’d expect from bench storage — nothing structural — and the dial indicator face is clean and legible with no fogging or cracked crystal. The overall impression is a kit that has seen very little working use, consistent with the seller’s “great condition” assessment. As with any used metrology tool, it’s good practice to zero the gauge against a calibrated setting ring or a known-good bore standard before putting readings to paper — particularly if the work is tolerance-critical. That single step confirms the gauge is reading true and closes the loop on any residual uncertainty from storage.

Brand Information
Peacock is a brand of Ozaki Mfg. Co., Ltd., a Japanese precision instrument manufacturer with a long-standing reputation in the metrology and machine tool industry. Japanese-made measuring instruments from this tier — which sits alongside names like Mitutoyo, Teclock, and Käfer — are held in high regard for consistent movement quality, accurate graduation, and durability under toolroom conditions. Peacock products are widely used across Japanese manufacturing and have a solid following in Australian toolrooms where the combination of Japanese build quality and accessible pricing is appreciated.

Note on model marking: The listing title references the CC-3A series; the handle visible in the product image is stamped CC-3C 50–150mm. Both designations refer to Peacock’s 50–150mm dial bore gauge family. Buyers should verify the exact variant against Peacock/Ozaki documentation if model number precision is required for calibration records.
