Insize 60 Degree Center Gage (4810 Series)

Insize 60 Degree Center Gage (4810 Series) center gage, also known as a fishtail gage or thread center gage, is a precision tool commonly used in machining and metalworking. It serves multiple purposes, primarily in the cutting and inspecting of screw threads. The tool is typically made of hardened steel for durability and accuracy.

One of the main functions of a center gage is to set and check the angle of the lathe tool when cutting threads on a lathe. The gage has a 60-degree angle, which corresponds to the thread angle for standard Unified and Metric threads. By aligning the cutting tool with the gage, machinists can ensure that the tool is correctly positioned for accurate thread cutting.

Additionally, the center gage is used to check the pitch of screw threads. It has a series of notches or teeth that correspond to various thread pitches. By comparing these notches to the threads being cut, machinists can verify the pitch and consistency of the threads.

The center gage also features engraved scales for measuring threads per inch (TPI) and thread pitch. This makes it a versatile tool in both threading operations and inspections, ensuring precision and consistency in the manufacturing process. Its compact size and multifunctionality make it an essential tool in any machinist's toolbox.
