Description
Product Overview
The Eisen EP-0B Pin Gauge Set covers the 0.50–1.00mm range in 0.01mm increments — 51 individual gauge pins in a purpose-moulded carrying case. Each pin is a hardened, ground cylindrical gauge of known diameter, used wherever you need a definitive go/no-go answer on a bore, slot, or hole rather than a dial reading you have to trust. For toolroom work, press-fit checking, reamer qualification, or verifying small CNC-bored features, a pin gauge set like this removes ambiguity from the measurement loop entirely.
- 0.01mm increment coverage from 0.50–1.00mm — Fifty-one steps across a critical small-bore range means you can pin a hole to its exact nominal size, not just bracket it. That matters when you’re qualifying reamed holes for dowel pins, checking pilot bore diameters before pressing in a bearing, or verifying a wire EDM feature against print tolerance.
- Individual labelled pins in dedicated slots — Each pin sits in its own moulded slot with the size clearly marked on the storage block. No rummaging through a bag of loose pins mid-job; you pull what you need, confirm the size by sight, and it goes straight back to its labelled home. Keeps inventory checks honest and prevents mix-ups on the bench.
- Hardened and ground construction — Pin gauges only hold their value as a reference if the measuring surface stays round and to size. Hardened pins resist the incidental contact wear that would quickly take a soft pin out of tolerance in regular shop use. Ground to a consistent surface finish, they’ll seat cleanly in a bore without false drag or slack.
- Purpose-built carry case with moulded organisation — The rigid case with labelled grid positions means the set travels safely between the machine and the inspection bench without pins rolling loose or taking knocks. For a shop running multiple jobs, it also makes a quick visual audit dead easy — missing pin slots are obvious at a glance.
- Ideal for: qualifying reamed and bored holes to dowel-pin fit, go/no-go checking of wire EDM slots and profiles, setting up small-bore air gauging, verifying drill and reamer sizing before committing to a production run, and checking nozzle or orifice diameters in pneumatic and hydraulic work.
Condition
New Old Stock (Unused / Original Packaging, All Accessories Present)
These pins present as unused. The set arrives in its original moulded storage case with all 51 pins present across the 0.50–1.00mm range, and all original accessories are included. Pin surfaces show no evidence of insertion wear, scoring, or contact marks — the ground cylindrical surfaces are clean and bright with no patina or corrosion visible. The storage case and individual pin labelling blocks are intact and undamaged. As with any NOS precision tooling that has been stored rather than freshly calibrated from the factory, verification against a certified ring gauge or optical comparator before using the set as a primary standard in a formal QA environment is a sensible first step. For workshop go/no-go checking, bore qualification, and toolroom reference work, these pins are ready to use straight from the case.
Included:
- 1 x Eisen EP-0B Pin Gauge Set, 0.50–1.00mm, 0.01mm increments (51 pins)
- Original moulded storage / carry case
- All original accessories as supplied by Eisen
Not included: Calibration certificate (recommend verification against a master ring gauge if formal traceability is required).
Brand Information
Eisen is a Japanese precision tooling brand with a long-standing presence in the Asian and export metrology market, producing gauge pins, plug gauges, and associated inspection tooling to Japanese Industrial Standards (JIS). Eisen sits in the same practical tier as Niigata Seiki and similar JIS-compliant Japanese gauge manufacturers — a step below the top-end Mahr or Mitutoyo certificate-grade product, but well above generic OEM pin sets, with ground tolerances and hardened construction that make them credible workshop and toolroom references. Japanese manufacture remains a strong positive indicator for pin gauge sets, where consistent grinding quality and material hardness directly determine how long the tool holds its stated size in regular use.
