What is an h6 tolerance?
A hole that has a 0.030” diameter will have an h6 tolerance of (+0.0000,-0.0002), while a 1.00” hole with have an h6 tolerance band of (+0.0000,-0.0005). It is important to note that most sources list IT tolerances in millimeters, while the graph below has been translated to inches.
How do you calculate fits and tolerances?
The dimensions of a fit are calculated using the tolerances according to ISO 286 (2010). In addition to the deviations of shaft and hub, the span, clearance or interference of the fit is shown as result. The tolerances according ISO 286 are defined up to 3150mm or up to 500mm dependend on the selected tolerance field.
What does H7 g6 mean?
In this capital letter H denotes hole and small letter g denotes shaft. This combination H7-g6 denotes the clearance fit. It can be seen in the table below the various types of fit according to the hole shaft system.
What means H7?
International Tolerance grades They are labelled with a letter (capitals for holes and lowercase for shafts) and a number. For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit.

What is an H6 shrink fit holder?
With an h6 shrink fit holder, the result is a secure connection with stronger gripping power. However, only certain shanks are able to be used with this type of holder.
What are the benefits of a shrink fit tool holder?
Benefits of Shrink Fit Tool Holders Gripping power. The shank is held flush and uniform against the holder, resulting in a tighter connection. Low runout. A more secure connection will result in extended tool life, and a higher quality surface finish. Better balance for high RPM.
What is the H6 tolerance of a hole?
For example, a tolerance with the number 6 will have a smaller tolerance range than the number 7, but larger than the number 5. This range is based on the size of the shank. A hole that has a 0.030” diameter will have an h6 tolerance of (+0.0000,-0.0002), while a 1.00” hole with have an h6 tolerance band of (+0.0000,-0.0005).
