Measurement tools for workshop and engineering use that transfer internal dimensions to a micrometer with repeatable results. Practical users and technicians will appreciate the straightforward six-piece set and hardened contact points, YUMILI Telescopic Gauge Set. Is the construction robust enough for regular shop work?
⚡ At a Glance
- • Measurement Accuracy: Accuracy 0.1 with precision-ground contact ends for consistent readings
- • Best for: Workshop technicians, hobby machinists and schools needing internal measurements
- • Not ideal for: High-precision calibration labs requiring traceable certified gauges
Six-piece telescopic gauge set measures inner diameters from 8-150mm and transfers sizes to a micrometer. Hardened, heat-treated and chrome-plated contact points with self-centering plungers aid repeatable measurements.
Accurate internal measurements – with hardened tool steel contact points
Contact points are made from hardened tool steel with heat treatment and chrome plating, and ends are precision ground to a radius to allow proper clearance in small holes. Double-action plungers are rigidly attached and self-centering for stable contact.
Consistent surface hardness and ground ends reduce wear and help deliver repeatable readings. Users can transfer measurements confidently to a micrometer without frequent rework.
Fast hole checking – with telescopic adjustable design and locking handles
Telescopic gauges expand inside holes and lock in position, capturing the internal size which is then measured externally with a micrometer. Double-action handles make expansion and secure locking straightforward.
Quickly assess holes, slots and recesses without complex set-up. The process speeds routine inspections and reduces time spent measuring multiple features.
Durable for workshop use – with chrome-plated surfaces and rigid construction
Chrome plating on contact points helps resist corrosion while the overall build uses heat-treated components for high rigidity and wear resistance. Constant spring tension maintains uniform contact pressure.
A robust finish and construction make the gauges suitable for regular shop handling and basic jobbing tasks. Expect the set to hold up as a practical replacement or backup for lost or damaged gauges.

❓ Frequently Asked Questions
Q: What size range do the gauges cover?
A: The set covers internal diameters from 8mm up to 150mm, supplied as six telescopic gauges.
Q: How are measurements taken with the gauges?
A: Expand a gauge inside the hole, lock the handle, withdraw the gauge and measure the spread with a micrometer to determine the final size.
Q: Are the contact points durable for workshop use?
A: Contact points are hardened tool steel with heat treatment and chrome plating for good wear resistance and durability.
