Carbide Bound Plug Gauge H7 (for machining)

Plug gauge made with long-life carbide alloy that has excellent abrasion resistance.
[Features]
· A pair of gauges with external dimensions based on the maximum and minimum allowable dimensions as references.
· Can be used for obtaining fit compatibility between the hole and the shaft.
· Excellent abrasion resistance and very economical with a lifespan approximately 20 to 30 times longer than steel.
· Low thermal expansion coefficient (1/2 that of steel, 5x10-6/K) reduces the influence of temperature.
· High hardness eliminates worries about scratching the surface.
· Gauge management is easy. (The periodic gauge inspection interval is lengthened, making it economical.)
[Applications]
· Used for hole diameter inspections.
