McKissock breast keyhole caliper 42.0mm diameter with cm marks

Clear, Consistent Measurement for Dental Workflows

The McKissock breast keyhole caliper is a precision measuring instrument designed to assess dimensions using a 42.0 mm diameter reference and an integrated centimetre scale. Its caliper format supports controlled comparison and repeatable visual measurement where clear dimensional information is important during dental instrument workflows. The cm marks make readings easier to interpret directly at the point of use, helping reduce reliance on separate measuring tools and supporting efficient documentation. A focused design can be useful when practitioners need a straightforward way to check or compare measured areas while maintaining careful instrument handling.

Use Cases

• Measure or compare dimensions using the 42.0 mm caliper diameter as a defined reference.
• Read measurements directly from the integrated cm marks during dental instrument workflows.
• Support visual dimensional assessment where a dedicated caliper is preferred over estimating by eye.
• Use as part of a controlled examination or documentation process requiring recorded centimetre measurements.

Specifications

Care & Handling

• Clean the caliper according to facility procedures and the applicable instrument-care instructions.
• Inspect the measuring surfaces, keyhole area, and cm markings before use for visible soil, damage, or loss of legibility.
• Handle the instrument carefully to preserve alignment and measurement readability.
• Store in a clean, dry location where the caliper and its markings are protected from impact or abrasion.
