Quantity:
Typically used in combination with a flat reference tool, such as a straightedge or a surface plate, a feeler gauge is used as a variable go/no-go gauge to determine how much a surface is out of true. It is also handy when adjusting plunge stops, fences or planer knives.
The fingers of a standard set are often too short; these are 1/2" wide by 5 1/2" long. This length is ideal, allowing you to reach into a space and still see what you are doing. The longer length also lets you use built up combinations (e.g., 0.025" + 0.002") without distortional error. The set runs from 0.0015" to 0.035" and is manufactured to meet exacting engineering standards (DIN 2275). The gauges are fashioned from hardened and polished high-carbon steel.
