RS PRO Internal Micrometer, Range 12 mm →20 mm

This 3-point bore micrometer set is used to measure bore depths between 12 mm and 20 mm. It's particularly suitable for automotive and manufacturing applications where you need to measure the depth of a pipe or cylinder.

The micrometer set features an extension rod for extra-deep bore measurement and a calibration ring gauge to easily adjust the anvils back to zero. The anvils are made of tungsten carbide, which is resistant to impact and corrosion and lasts up to 100 times longer than steel. The thimble also has a satin chrome finish for increased hardness, giving you a durable and long-lasting set.

You'll find this product particularly handy for the automotive industry. It's commonly used to measure the holes in an engine block, ensuring a tight fit for pistons. As part of the RS PRO range, it meets our stringent quality and accuracy standards.
