Product Overview

The Teclock CC-150 Dial Bore Gauge is a complete, ready-to-use internal measurement set covering the 50–150mm range — the bread-and-butter bore sizes you’ll encounter day-in, day-out on a production lathe or machining centre. Built around a quality Teclock dial indicator reading to 0.01mm with a 5mm total travel, this set gives you the reach and resolution to confidently check cylinder bores, housing fits, bushing IDs, and reamed holes against tolerance without reaching for a digital unit. The full complement of interchangeable anvil extensions is present and accounted for, the wooden case is intact, and the whole set presents in condition that suggests minimal to no actual use.

50–150mm measuring range with a full anvil extension set — that 100mm span covers the majority of bores a jobbing shop or toolroom will encounter, from medium chucking work right up to larger housing bores. Having every extension present means you’re not hunting for a missing spacer mid-job.
0.01mm graduation dial indicator with 5mm travel — at one hundredth of a millimetre, you have the resolution to hold H7/f7 and similar class fits with confidence. The 5mm total travel on the indicator gives you genuine working headroom when rocking the gauge to find true minimum (the correct technique for accurate bore reading).
Centralising bridge and replaceable contact points — the self-centring bridge ensures the gauge sits on the bore’s true diameter rather than a chord, which is the difference between a useful reading and a meaningless one. Replaceable contacts mean the tool has a long service life even in production use.
Compatibility / accessories — the gauge head accepts the Teclock dial indicator supplied; setting the zero requires a calibrated ring gauge or an outside micrometer used as a setting master (neither is included). The supplied wooden case keeps all extensions organised and protects the indicator during storage.
Ideal for — checking bored-to-size cylinder and housing bores on the lathe or machining centre, verifying reamed bushing IDs to drawing tolerance, inspecting worn engine cylinder bores during rebuild work, confirming bearing housing fits before press, and quality-checking repetition turned parts against a ring gauge master.

Condition

(Used — Like New / Possibly Unused or NOS)

The set presents exceptionally well for its age. The dial indicator face is clean and unmarked, the needle moves freely and returns crisply with no detectable drag or stiction — a good sign that the rack-and-pinion mechanism inside the indicator body is in sound working order. The bore gauge body, bridge assembly, and stem show no visible wear marks, score lines, or damage to the measuring contacts. The anvil extensions housed in the wooden case are all present and seated in their correct foam slots; surfaces are clean with no pitting or corrosion. The wooden storage case has minor age-related patina on the exterior but the foam insert is intact and holding everything securely. Overall impression is consistent with a set that either left the shelf once or was simply stored after very limited use. As with any used precision instrument — regardless of condition — we recommend setting the zero against a calibrated ring gauge or a known outside micrometer master before committing the tool to inspection work. This is standard practice and not a reflection of any identified fault.

50mm reference spacer / setting piece
Original fitted wooden storage case with foam insert

Not Included

Setting ring gauge or bore gauge master (required to zero the instrument prior to use — not supplied)
Calibration certificate

Brand Information

Teclock Corporation is a Japanese precision instrument manufacturer founded in 1950 and headquartered in Nagano Prefecture — the same region that produced many of Japan’s most respected metrology brands. Teclock produces a broad range of dial indicators, thickness gauges, and bore gauges that sit in the same credible mid-to-upper tier as Peacock (Ozaki) and Federal, and are used in production and toolroom environments across Asia, Europe, and Australia. Japanese manufacturing heritage means tight process control, consistent graduation accuracy, and components that hold up over genuine working life — attributes that matter when you’re checking a bore to a few microns of your H7 limit.
