Cutter Size Converter

Convert inch and millimeter cutter dimensions accurately without treating a nearby metric size as an exact inch equivalent.

Cutter dimension

Input units

0.7500 in = 19.050 mm

Conversion uses exactly 25.4 mm per inch. Decimal output is rounded for display; it is not a machining tolerance or cutter-fit approval.

For example, 3/4 inch is 19.05 mm, not exactly 19 mm. A nominal shank label still requires the correct interface, flats and retention system.
