Measuring tools for reliable inner-diameter checks, aimed at quick and repeatable readings in workshops and garages. Confidence when inspecting bores and recesses reduces rework and speeds up routine checks. Is the Tyenaza Telescoping Gage Set the right choice for a small engineering shop or keen home machinist?
⚡ At a Glance
- • Measurement Accuracy: Fine repeatability across the 8–150 mm range with minimal play
- • Best for: Workshop technicians, toolmakers and hobby machinists needing reliable bore checks
- • Not ideal for: External diameter measurement or tasks requiring certified calibration standards
Six telescoping gauges cover an 8–150 mm inner-diameter range. Precision-ground, head-treated steel contacts and uniform spring tension support repeatable readings.
Reliable repeatable readings – With precision-ground contact heads
Contact ends are head-treated steel and precision ground to a radius, giving correct clearance on the smallest hole the gauge will enter. Ground surfaces reduce wear and help maintain geometry over repeated use.
Accurate transfer of internal dimensions to a micrometer enables consistent measurements cycle after cycle, reducing scatter between checks.
Faster internal checks – Thanks to double-action, self-centring handles
Double-action handles are rigidly attached to the contact plungers and operate to centre automatically, while constant spring tension ensures a uniform contact pressure across the contact faces.
Quicker set-up and fewer adjustments when measuring holes, slots and recesses up to 6 inch deep, making inspection routines noticeably faster.
Secure measurement retention – With robust locking and sturdy construction
A locking mechanism holds the expanded gauge position after extraction, supported by high rigidness and wear-resistant materials in the build.
Locking preserves readings during transfer to a micrometer, cutting down on handling errors and improving workflow reliability.
