Product Details
Versatile direct-reading chamfer gage for measuring the diameter of internal chamfers over the highly useful 0–1" range. Its broad capacity makes the 683-3Z an excellent general-purpose choice for machine shops, inspection departments and quality laboratories.
Premium mechanical chamfer gage designed for direct measurement of the diameter of internal chamfers. The hardened measuring surfaces and AGD-style indicator make this a strong production-floor and inspection-room instrument.
Starrett's current documentation confirms that the 683 series covers 0–90° internal chamfers and directly measures chamfer diameter without requiring a setting master.
Choosing a Range
The 683-3Z (0–1") is the featured, general-purpose choice. The 683-2Z is the compact 0–1/2" range, with 0–3/8" and 1–2" also available. Select the range in the dropdown above.
Angle Coverage
The 683 series covers 0–90° internal chamfers. For the complementary 90–127° angular range see the Starrett 684; for chamfers on an outside diameter see the Starrett 685 external chamfer gage.
