Definition and Purpose of Center Gauges
– Center gauges are used in lathe work for checking angles when grinding tool bits and centers.
– They help in grinding the profiles of single-point screw-cutting tool bits.
– Center gauges are essential for setting the tool perpendicular to the workpiece.
– They are commonly used when hand-grinding threading tool bits on a bench grinder.
– Center gauges can also be used with tool and cutter grinders.
Types of Center Gauges
– Center gauges come in different styles and designs.
– The fishtail gauge is a common type of center gauge.
– There are other styles of center gauges available as well.
– These gauges can incorporate various sizes and types on a single gauge.
– Some common types include metric or UNC and UNF at 60°, and BSW at 55°.
Applications of Center Gauges
– Center gauges are primarily used in lathe work.
– They are used for grinding tool bits and centers.
– These gauges are crucial for achieving the correct angle in tool grinding.
– Center gauges are used to ensure the tool is perpendicular to the workpiece.
– They play a vital role in achieving accurate threading on a lathe.

Center gauges and fishtail gauges are gauges used in lathe work for checking the angles when grinding the profiles of single-point screw-cutting tool bits and centers. In the image, the gauge on the left is called a fishtail gauge or center gauge, and the one on the right is another style of center gauge.
These gauges are most commonly used when hand-grinding threading tool bits on a bench grinder, although they may be used with tool and cutter grinders. When the tool bit has been ground to the correct angle, they are then used to set the tool perpendicular to the workpiece.
They can incorporate a range of sizes and types on the one gauge, the two most common being metric or UNC and UNF at 60°, and BSW at 55°. Gauges also exist for the Acme thread form.
