Precision Boley Gauge Caliper in Surgical-Grade Stainless Steel
The Boley gauge is a direct-reading sliding caliper, valued by technicians for its simplicity and reliability in fine work. This model is constructed from a single piece of surgical-grade stainless steel, offering excellent durability and resistance to corrosion.
Its highly polished surface is not just for aesthetics; it ensures the tool can be easily and thoroughly cleaned or sterilised in an autoclave, making it suitable for clinical or clean-room environments. The classic, unadorned design is ambidextrous and provides clear, direct measurements without the need for batteries or complex readouts.
Commonly used by dental technicians for measuring crowns, jewellers for sizing gemstones, and model engineers for checking component tolerances.
