Measuring Tools Set Manufacturer,Supplier and Exporter in India
Product Code : EL-CLE-9068
Jlab Export is a leading Measuring Tools Set Manufacturer,and suppliers in India
This measuring tools set equips a workshop class with vernier calipers and micrometers. It has ten 150 mm vernier calipers for outside, inside and depth readings. It also has ten outside micrometers, five of 0–25 mm and five of 75–100 mm, plus one 25–50 mm inside micrometer. Every micrometer reads to 0.01 mm and can be locked at any position.

Workshop Practice with the Measuring Set
In a fitting or machine shop practical, students check the diameters of a turned job with a vernier caliper. They then confirm the finished size with a 0–25 mm outside micrometer. Steps and slot depths are read with the caliper depth bar. Marking out before machining is done with a Steel Rule and an Engineers Square.
The 75–100 mm micrometers suit larger shafts and collars, and the inside micrometer checks bores from 25 to 50 mm. A good class exercise is to measure one part with three tools, a vernier caliper, a micrometer and a Dial Caliper. Students then explain why the readings differ in the last decimal place.
Frequently Asked Questions
What is the least count of the calipers and micrometers in this set?
The vernier calipers read to 0.05 mm on the metric scale and 1/128 inch on the inch scale. The micrometers read to 0.01 mm. The least count is the smallest change in size each tool can show.
How do I check a micrometer for zero error?
Clean the anvil and spindle faces, then close them gently with the ratchet or friction drive. On a 0–25 mm micrometer the thimble zero should line up with the datum line. A 75–100 mm micrometer is zeroed against a 75 mm setting standard instead.
Why use the ratchet stop or friction drive when measuring?
Both limit the force on the spindle, so each reading is taken at the same light pressure. Turning the thimble directly can squeeze the work and give a small reading. When the drive slips, lock the spindle and read the scales.
Can the vernier calipers measure bores and depths?
Yes. The main jaws measure outside diameters and thicknesses, the inside jaws measure bores and slot widths, and the depth bar measures steps and blind holes. The lock screw holds the slide while you read the scale.
What mistakes do students make most often when reading these tools?
The commonest is reading the main scale at the edge of the slide instead of at the vernier zero. Others are choosing the wrong coinciding line, skipping the zero check and measuring with dirt on the faces. On a micrometer, students often miss the half millimetre line on the sleeve.
