Caliper faster tools 05-2-0100 150mm digital/mechanical measuring tool

Caliper faster tools 05-2-0100 150mm digital/mechanical measuring tool is a compact caliper designed for accurate linear measurements up to 150 mm. Combining mechanical scale and digital readout, it provides measurement of external and internal dimensions as well as depths. The tool is intended for workshop, home and professional environments where reliable, repeatable measurements are required for metalworking, woodworking and general measuring tasks.

Advantages

The caliper offers dual-mode operation with both a clear mechanical scale and a digital display for quick numerical readings. Its 150 mm measuring range and fine jaw geometry allow close access to small features, while the depth probe enables measurement of recesses and steps. Compact construction and ergonomic thumb roller ensure stable positioning and comfortable handling during routine inspections. The device is built for everyday use and provides consistent accuracy for various materials and applications.

Suitable for

• Measuring external diameters of parts and components
• Measuring internal diameters such as bores and slots
• Measuring depth of holes, grooves and steps
• General workshop layout, fitting and assembly checks
• Woodworking size checks and hobbyist projects

Key specifications

• Measuring range: 0–150 mm
• Measurement types: external, internal, depth
• Display: digital readout plus mechanical vernier/scale
• Material and finish: metal body with precision-ground jaws
• Adjustment: thumb roller and locking screw for fixed readings
• Resolution: fine graduations suitable for precise linear measurement
• Weight and dimensions: compact, hand-held form factor for easy handling

How to use

Place the caliper jaws around the object to measure external dimensions, or insert the internal jaws into a bore and expand until they contact the walls. For depth measurement, extend the depth probe into the hole or recess until it seats on the bottom. Use the thumb roller to make fine adjustments and the locking screw to secure the jaws before reading the value on the digital display or mechanical scale. Ensure the measuring faces are clean and the caliper is zeroed before each critical measurement to maintain accuracy.

Usage recommendations

Store the caliper in a protective case when not in use, avoid exposure to liquids or heavy contaminants, and periodically check calibration against a gauge block or reference standard. Clean measuring faces with a lint-free cloth and keep the slide mechanism lightly lubricated to ensure smooth operation and long service life.
