An angle gauge block set, also known as angle gauge blocks or sine gauge blocks, is a precision tool used to
measure and set specific angles with a high degree of accuracy. These blocks are typically used in machining,
inspection, and metrology applications where exact angular measurements are required, such as setting up equipment,
verifying the accuracy of angled features, or calibrating other measurement instruments.

• For angle comparison
• One angle can be as used in triangle blocks four angles can be as used in rectangle blocks

Applications of Angle Gauge Block Sets:

• Precision Machining: For setting up equipment to cut or
  machine parts at exact angles.
• Tool and Die Making: Essential for setting angles in dies,
  molds, and cutting tools.
• Quality Control and Inspection: Used in metrology labs
  or quality control settings to verify that angular dimensions meet specified
  tolerances.
• Calibration of Measuring Tools: Angle gauge blocks are
  used to calibrate tools like protractors, angle finders,
  and other angular measurement instruments.
