.080"-8"/2-200MM measuring tool is usually a matter of preference, but
there are some differences.
AccuBore is a high-quality, trigger-activated, two-point and three-point contact bore

What makes AccuBore superior to other gages are features like the mechanically-driven

• Bluetooth capability in that it can be seated in position more quickly than

• Single-hand operation with right- and left-hand viewing flexibility a two-point contact tool.
• Large, easy-to-read display Usually these tools can also be read to a finer
• Enhanced wear life with carbide-faced contacts – available from 1/2" to 8" accuracy. The three-point tool will tell the maximum
true diameter that can enter the hole a little faster
• Convenient "Go/No-Go" tolerance indicator lights than a two-point contact tool.
• True alignment with mechanically-driven parallel anvils Micrometer heads used in these tools are accurate
• Resolution .00005" (0.001mm) to ±.0001" or 0.002mm, but overall accuracy on
• Accuracy of up to .00015" (.004mm) tools that add rods is dependent on good practice
• Push button inch/metric conversion and technique.
• Preset and preset recall To ensure accuracy, these practices should be followed:
• Hold, max/min and zeroing capabilities • Always make sure that there are no specks of

• Output capability for Statistical Process Control (SPC) analysis. Download data too loosely, but a fairly firm assembly
via USB to a PC or RS232 connection. • Assembling long sections should be done
vertically or, with support, horizontally
• Because temperature can affect long rods used
in these tools, they should be assembled in the
same environment in which they will be used
