Neoteck Bore Gauge Set Digital Indicator Dial Bore Gauge (2-6"/0.0005") with Self-Centering Dial,Carbide Anvils, Insulated Grips for Deep Engine Cylinder Measurement-Black

I had originally bought an analog type bore gauge. The spring loaded housing that houses the contact point seemed a bit loose and I wondered if that would negatively impact any readings.I went ahead and bought this one. This has an LCD digital read out. Its housing was not as loose. After zeroing out the gauge, I used it to measure some cylinder bores and I feel it was providing accurate readings.I did reached out to the makers customer support and they never replied, so can’t give that a thumbs up.I would recommend this item.

Bought this for my engine rebuild. I had to figure out how to measure with it as the instructions are not the clearest. It’s good to 3 decimal points, plus a half thou when exceeded. This was enough for my purposes. If I need a more accurate value, I use a Plastigauge.Basically, you first need to find the right stem, potentially in combination with a spacer, that fits in the ID you wish to measure. Note that the little nib on the opposite side of the stem needs to touch and be able to deflect within the ID of the cylinder you’re measuring. Once you have the ‘dial’ indicator rigged properly, you then measure the length of the measuring end, and to determine the actual diameter, subtract the indicated ‘compressed’ value from the uncompressed length of the measuring tool. My engine piston sleeves definitely need to be replaced.

Works as intended.

I used this digital bore gauge to measure my piston bore, and it performed flawlessly. The digital readout is clear and easy to read, and the gauge provided consistent, precise measurements. It helped me ensure that everything was within spec during my engine rebuild. The build quality is solid, and it feels like a high-quality tool. Definitely worth the investment for anyone doing precision work. Highly recommended! Very accurate!

Makes measuring bores easier as heck.For the price, it is worth it and I get repeatable measurements to .01mm Everytime. Using a telescopic gauge took me 30+sec for an inaccurate reading, this literally takes 2 sec.Only downside, is the digital dial indicator stays on for about 3 minutes until it shuts off which is good for battery, but it doesn't have any memory, it rezeros itself and I have to zero it out each time I go to measure after honing. The stem is a different size from my other quality miyutoyo dial

Great tools 🔧

Like every tool, it has it's own "personality" and you have to use it several times to get repeatable and accurate results. I'm okay with that.My only complaint is the LCD display is difficult to read. If you're looking square on in good lighting it's fine but if you have marginal lighting or looking off axis, it's almost unreadable. In particular the - (minus sign) hardest to read.The lighting is rarely perfect and I often have to do machinist yoga to see whatever I'm working on. A good display is important.
