Master Precise Groove Measurements with Confidence
When precision matters most, trust our Digital Internal Groove Caliper to deliver accurate, repeatable measurements every time. Specifically engineered for measuring external and internal grooves, slots, and recesses, this professional-grade tool eliminates the guesswork from complex workpiece inspections.
Uncompromising Accuracy
Achieve reliable results with 0.01mm resolution and ±0.005" / 0.05mm accuracy. The parallel high-precision jaws are meticulously crafted to ensure consistent contact with groove surfaces, providing you with trustworthy data for quality control and machining operations.
Built for the Toughest Environments
Constructed from premium 3CR13 stainless steel, this caliper withstands the rigors of daily workshop use. The hardened material resists wear, corrosion, and deformation—maintaining its precision even after repeated drops or exposure to cutting fluids and debris. The dual-scale markings (metric and inch) are permanently laser-etched, ensuring they remain legible for years to come.
Engineered for Efficiency
The large LCD display offers instant, crystal-clear readings from any angle, reducing eye strain during extended use. Power comes from a standard LR44 button cell battery, providing months of continuous operation. When replacement is needed, the accessible battery compartment makes it a 10-second task.
Complete Protection & Portability
Each caliper ships in a custom-molded plastic storage case. The rugged case protects your investment from dust, moisture, and impact damage—whether stored on a shelf or tossed into a travel bag for on-site inspections.
Ideal For:
Machinists & CNC operators measuring groove depths and widths
Automotive technicians inspecting piston ring grooves and bearing seats
Quality control professionals performing incoming/outgoing part inspections
Tool & die makers verifying mold and die cavity dimensions
