Description
Product Overview
This TC 0.50–1.00mm Gauge Pin Set (Class CC-0B) gives you a complete, finely graduated run of cylindrical pin gauges in 0.01mm increments — exactly what you need when you’re checking bored holes, verifying reamed diameters, or qualifying go/no-go fits on the bench without reaching for a bore mic every time. Fifty-one individual pins, each ground to a precise diameter and clearly labelled, housed in the original fitted case. If you’re doing close-tolerance work in the sub-millimetre range, a quality set of gauge pins is faster, more repeatable, and more traceable than relying on an adjustable gauge alone.
- 0.01mm increment steps across the full 0.50–1.00mm range — With 51 pins stepping in 0.01mm increments, you can quickly bracket a bore or feature to within one hundredth of a millimetre before committing to a final measurement. That level of granularity is what separates a proper pin set from a coarse go/no-go pair when you’re chasing tight fits on instrument bores, watch component housings, or precision jig work.
- Class CC-0B accuracy grade — The CC-0B designation indicates a close-tolerance ground and lapped pin surface, giving you a reliable ground reference you can actually trust for qualifying holes rather than just estimating. This grade is suitable for toolroom inspection and production checking where a calibrated reference is required.
- Cylindrical pin form with knurled handles — Each pin is fitted into a knurled grip body, making single-handed insertion and extraction in a bore straightforward without contaminating the ground surface with bare-hand oils. The knurled body also gives you tactile feedback when a pin transitions from sliding fit to interference — useful when you’re feeling for the exact size.
- Original fitted case with lubricant bottle and accessory rod included — The case keeps every pin indexed, sorted, and protected from bench clutter and cross-contamination. The included lubricant bottle and what appears to be a cleaning/handling rod mean the set is ready to use as a complete kit without sourcing accessories separately.
- Ideal for — Checking drilled and reamed bores on jig plates and fixture bodies, verifying jeweller’s and watchmaker’s bores, qualifying carbide guide bush internal diameters, checking CNC-machined features before assembly, and confirming drill sizes against a ground reference rather than relying on drill markings alone.
Condition
Used (Good Condition / Complete Set in Original Case)
The set presents in genuinely good used condition. The pins themselves show no visible damage, deformation, or corrosion on the ground surfaces — the critical functional faces appear clean and intact with normal light handling patina consistent with careful workshop use. The knurled grip bodies are all present and legible, with labels clearly readable across the full range from 0.50mm through to 1.00mm. The fitted case retains its original foam/card insert, keeping all pins correctly indexed in their labelled positions. The included lubricant bottle and accessory rod are present. Two pins in the fourth row (visible as 0.81 and 0.82) appear to be seated or oriented slightly differently in the photograph — this is noted for transparency, though this is likely a seating or orientation issue within the case rather than a defect with the pins themselves. As with any pre-owned gauge pin set, it is recommended that you verify critical pins against a calibrated ring gauge or optical comparator before use in a formal inspection role. For workshop qualifying, hole-checking, and toolroom use, this set is ready to put straight to work.
Included:
- 1 x TC Gauge Pin Set, 0.50–1.00mm, Class CC-0B (51 pins in 0.01mm increments)
- 1 x Original fitted storage/inspection case
- 1 x Lubricant/protective oil bottle
- 1 x Accessory handling/cleaning rod
Not included: Calibration certificate (not present — recommend verification against a traceable ring gauge if formal inspection traceability is required).
Brand Information
The “TC” designation on these gauge pins is consistent with Japanese-manufactured precision metrology tooling produced for the industrial inspection and toolroom market — a sector where Japanese manufacturers have long held a reputation for tight process control, consistent material quality, and reliable ground surfaces. Japanese gauge pin sets of this type sit in the same production-quality tier as offerings from RSK and similar mid-to-upper toolroom brands, delivering accuracy and surface finish that exceeds generic OEM imports from less controlled origins. While TC is not as broadly marketed internationally as Mitutoyo or Tesa, Japanese-origin gauge tooling of this grade is well regarded on the shop floor for its consistency and dimensional reliability.
