  • Stainless steel construction resists wear and corrosion
  • Laser-engraved dual metric and imperial scales read clearly

Precision Vernier Caliper With Carbide Scriber

This 20 cm vernier caliper is built from polished stainless steel and includes two replaceable carbide needles for layout work. The dual metric and imperial scales are laser engraved for clear, wear resistant readings. It suits machinists, engineers and hobbyists who need accurate measurement and scribing in one tool.

Measurement Accuracy And Durability

The instrument delivers an accuracy of 0.05 mm or 1/128 inch across its range. Hardened tungsten steel scribes mark clean lines on wood, plastic and metal without dulling quickly. Fine polishing and laser etching keep the graduations legible through daily shop use.

Removable Needle Design For Workshop Flexibility

Each carbide needle measures 3.40 cm long by 2 mm in diameter and threads into the caliper jaw for secure mounting. A spare needle is supplied in the package so work continues uninterrupted if one tip is damaged. The removable design allows quick replacement with standard spares.

Questions about this item

How do I mount the carbide scriber needle on the 8 inch vernier caliper and what step is often missed?

Slide the needle into the dedicated holder on the caliper body and tighten the locking screw; the step often missed is checking that the needle tip sits flush with the jaw face before securing it.

What replacement parts will the 20 cm vernier caliper need over time?

The carbide scriber needles wear with use on hard materials; the package includes two needles and spares are available under.

At what measurement tolerance does the 0.05 mm accuracy limit become the limiting factor during sustained layout work?

The stated accuracy of 0.05 mm or 1/128 inch defines the smallest reliable increment; beyond this the scale resolution and needle deflection become the limiting factors.
