radius diameter hole gauge

Do you ever need to measure the diameter of a hole? Or measure the radius of a fillet? This might be just the little tool you are looking for!

• Measures inside and outside curves
• Measures hole diameters, which inside radius tools will not do.
• multipurpose
• accurate
• Outside curves measurement is easily accurate to +/- 0.5mm, as good as flat radius measurement sets
• Inside curves are easy to read

Some downsides in measuring holes:

• the hole must be deep enough
• (a little) more difficult to read if there is a chamfer on the top of the hole
