SER 200 Fractional reamers can be ordered to specific diameters according to the size range
of Cutting Diameter D
1
. Please order as:
• 200. Then the size of the cut diameter in fractional format.
• i.e. 200.0492
• Description: Series 200 size 0.0492
• For Metric sizes convert to fractional inches (i.e. ÷ 25.4)
• The above sample would be a 1.25mm size (1.25 ÷ 25.4 = 0.0492")
All other dimensions are fractional as per table including the Shank
