Dial Bore Gauge 2"-6" / 0.001" Engine Hole Cylinder Measurement Gage Inside Micrometer Dial Indicator for Bore Measure Cylinder Tool Kit

A 2–6 inch dial caliper is a precise and easy-to-use measuring tool, ideal for medium-sized objects. Its clear dial display allows quick readings, and the durable construction ensures long-lasting performance. While it may require occasional calibration, it remains a reliable and battery-free option for accurate measurements.

good quality build, accurate easy to use and it's very versatile.

I used this bore gauge to measure a 650cc motorcycle bore with a 100mm bore (big slug). I zeroed the gauge using a 3-4” inside micrometer at the 100mm dimension, and then measured the bore for wear in multiple directions. Unfortunately, my bore was egg shaped front-to-back, so I ended up getting a new cylinder and keeping the old cylinder for an oversize bore in the future. But the gauge removed any doubts, and was well worth the small cost.

Ok

It works great.

Check engine bore

Great price

this is NOT suitable for measuring bore, or oil clearance on an engine. accuracy moves after every other reading and metal rollers gouged my bearings so bad they were ruined and I had to buy new.
