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 have used it a few time so far, and no issues. I do own a set of Mitutoya digital vernier calipers that are professionally calibrated and certified, and this bore gauge/digital indicator is right on the money according to it. I verified for any deviations and there were none. Since it's not something I use very often, I won't be able to attest of how well it does over time but, if you happen to need a bore gauge for your garage/hobbies, this is a nice piece at a really fair price. I trust it. (Used it to verify cylinder bore size, roundness and taper on a 454 block)

Great Value for the money! Well made and works as it should.

A little fiddly at first to set up, but works very well. Good product and excellent value.

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.

I used this bore gauge for the first time today and was pretty easy to use. Seems to be accurate as I could repeat my measurements consistently. Not bad for the price,

Worked perfectly for finding bore size. Digital takes away any guesswork

I'm a retired machinist and this is a quality product for the cost.

Accurate to 0.0005", or 5/10,000", or 0.01mm. Or "half a thousandth". In other words, the precision leaves just a little too much uncertainty regarding some particularly tight tolerances in my rebuild. Otherwise, great product all around. It's a good value, but it was the wrong tool (for me) to cheap out on. Just a matter of time until you need it and the batteries are dead though. Sure to be annoying.

Das Neoteck Bohrungslehre Messuhr Set deckt mit einem Messbereich von 50 bis 160 mm die gängigsten Innendurchmesser ab. Für den gelegentlichen bis regelmäßigen Einsatz in der Hobby-Werkstatt oder in kleineren Reparaturbetrieben bietet dieses Set ein überraschend gutes Preis-Leistungs-Verhältnis. Positive Aspekte: Die Messgenauigkeit ist zuverlässig und die Wiederholgenauigkeit liefert präzise Messergebnisse. Das mitgelieferte umfangreiche Zubehör (wechselbare Messdorne und Verlängerung) ermöglicht eine schnelle Anpassung an verschiedene Bohrungsgrößen. Die Messuhr lässt sich gut justieren, und die Bedienung ist dank der übersichtlichen Skala intuitiv. Die Spindel läuft sauber und gleichmäßig. Verbesserungspotenzial: Der mitgelieferte Aufbewahrungskoffer könnte etwas robuster sein, um das empfindliche Messwerkzeug optimal zu schützen. Wie bei Geräten dieser Preisklasse üblich, sollte die Messuhr regelmäßig auf ihre Nullstellung und Präzision überprüft werden. Fazit: Ein solides und zuverlässiges Messmittel für alle, die Zylinderbohrungen, Lagersitze oder andere Innendurchmesser präzise vermessen müssen. Klare Kaufempfehlung für Anwender, die Wert auf Genauigkeit zu einem erschwinglichen Preis legen.
