Description

This carbide pin gauge set is a high-precision dimensional reference tool dedicated to inner bore, small hole and groove width measurement, widely used for go/no-go tolerance testing, fixture alignment and measuring instrument calibration in mold manufacturing, precision grinding and hardware processing industries. Each pin gauge is precision lapped from high-purity tungsten carbide, delivering exceptional wear resistance and long-term dimensional stability — its service life is approximately 10 times that of ordinary steel pin gauges, maintaining reliable accuracy even under frequent daily inspection use. The 0.01mm uniform step increment enables continuous full-range bore measurement, effectively solving the limitation of vernier calipers in small precision hole inspection.

Premium Tungsten Carbide Material & Grade 1 Accuracy

All pin gauges are forged from high-purity tungsten carbide, hardened to HRC 62–65 with ultra-high wear resistance and anti-deformation performance. Each gauge undergoes precision lapping and 100% factory inspection, reaching Grade 1 industrial accuracy with diameter tolerance controlled within ±0.001mm. The mirror-finished surface ensures smooth insertion without scratching workpiece bore walls. Non-magnetic ceramic material is also available for special anti-corrosion and non-magnetic application scenarios.
0.01mm Fine Step Continuous Measurement

Each set contains 101 pin gauges with 0.01mm uniform step increment, realizing seamless continuous measurement within the corresponding range. It is suitable for precision bore inspection of mold inserts, precision hardware, medical components and electronic parts, providing reliable physical dimensional reference for tight-tolerance machining.
Complete Multi-Range Configurations

7 standard measuring range options are available to cover most common industrial bore sizes, and custom non-standard sizes are also supported to meet special inspection requirements.
Premium Wooden Storage Case With Dedicated Handle

Each set is packed in a high-quality wooden storage box with inner plastic positioning slots. Every pin gauge has an independent marked slot to avoid collision, wear and size confusion. The set is equipped with a dual-end pin gauge holding handle, enabling operators to grip gauges stably without direct hand contact, preventing hand sweat and body temperature from affecting measurement accuracy.
Retail-Oriented Global Shipping Configuration

Each pin gauge set is packed with an outer shockproof export carton, attached with full English specification sheet and factory inspection certificate. Standardized retail packaging is suitable for international express delivery, with clear packing dimensions and weight data for fast customs clearance.
