Gar E-9 | 16 - 250 Microinches Electrical Discharge Machined Microfinish Comparator w/9 Specimens

Electrical Discharge Machined Microfinish Comparator (EDM): Nine replicated EDM surface finish specimens ranging from 16 to 250 Microinches.

The E-9 Microfinish Comparator Surface Roughness Scale provides an economical tool which permits roughness to be specified on the same basis as linear measurements. Details covering this subject are now published in The American National Standards Institute (ANSI) specification titled: "Surface Texture, Surface roughness, Waviness and Lay".

Features:

• Roughness comparator scale for inspection
• 9 Precision finish specimens
• Range 16-250 Microinches
• Accuracy of a millionth of a inch 0.000001"
• Electrical discharge machined
• Genuine leather sleeve
