Starrett 683-3Z Inch Reading Internal

Starrett 683-3Z Inch Reading Internal Chamfer Gauge, 0-90 Degree Angle, 0-1' Range

Starrett offers a variety of innovative and good performing chamfer gauges, and this 683-3Z is one of them.
The product’s gauge plunger has an angle range of 0 to 90 degrees. For the capacity, it can read diameters up to 1 inch. This is perfect for those chamfer holes that you usually work with at the shop.

All ground surfaces of this model are of hardened tool steel. Also, its indicators are designed to meet American Gage Design (AGD) standards. This tells us that this chamfer gauge is built to be accurate and consistent.

In terms of accuracy, the product works in graduations of .001 inch. Just enough to see even the slightest inconsistencies in the product’s holes.
What’s more, this product does not need any setting master. However, it always is recommended to calibrate every measuring tool regularly.
You will also love the deluxe padded case it comes with. It will protect your gauge when not in use.

Starrett 683-2Z Inch Reading Internal Chamfer Gauge

Starrett 683-2Z Inch Reading Internal Chamfer Gauge, 0-90 Degree Angle, 0-1/2' Range

As the general rule in using chamfer gauges, the chamfer holes’ angle should be less than the gauge plunger’s angle. It is very easy to get this part right, as most models in this list offer a 0 to 90-degree plunger angle, which is mostly used in machine testing and inspection.

But what about the chamfer’s capacity? Do you feel like the 1-inch capacity models are too big for you? Are your chamfer holes extremely little, and you want a capacity that is just right? Well, you should check this model out.

The Starrett 683-2Z has a capacity of only 0 – ½ inch! If your work requires you to check such little chamfer holes, this model is perfect for you. The product’s angle, on the other hand, ranges from 0 to 90 degrees.

As a product from Starrett, we can expect great accuracy from it. The dial offers a gradient spacing of 0.001 inches. All its ground surfaces are of hardened tool steel, and they are designed by AGD standards. The product does not need any setting master.


  • Designed to follow AGD
  • Durable
  • Offers great accuracy
  • Easy to calibrate


  • Quite expensive
  • Capacity is too small for some

Flexbar Chamfer Gauge 0-1″ Capacity, 90-127 Deg Range

Chamfer Gage,0-1' Capacity,90-127 Deg Range

With previous models in this review, we have seen different gauge measuring capacities, but what about the chamfer gauge’s plunger range?
Inaccurate measurements will occur when the chamfer hole’s angle is greater than that of the gauge plunger. In this case, the measuring tool will erroneously register a diameter reading much smaller than it should. Nobody wants that, right?

That said, if your chamfer hole’s angle is larger than 90 degrees, then your chamfer gauge’s plunger should be much larger than that. This is why Flexbar offers us a chamfer gauge that has a bigger angle range.

Specifically, this model comes with an angle range of 90 to 127 degrees! It is the perfect tool to check the quality of holes with much wider angles. In terms of capacity, it can measure holes with diameters up to 1 inch.

What’s more, it offers a direct diameter reading to .001″. The 3 blades of the unit’s plunger are made from steel and are hardened and precisioned to provide high accuracy and repeatability.


  • Durable
  • No setting masters required
  • Offers great accuracy
  • Easy to calibrate


  • Can’t be used with smaller angles of chamfer holes

Starrett 684-3Z Inch Reading Internal Gauge

Starrett 684-3Z Inch Reading Internal Chamfer Gauge, 90-127 Degree Angle, 0-1' Range

Starrett has taken over our review list! Well, the quality of their products is really worth each penny.
Like the previous model in our list, Starrett offers us a product with a wider plunger range. The 684-3Z model can precisely measure chamfer holes with a diameter up to 1 inch, with a plunger range of 90 to 127 degrees.

When we talk about the dial itself, it comes with graduations of 0.001 inch. No setting master is required to get accurate measurements from the gauge. You just need to press the three-blade plunger in a flat surface, adjust the dial to zero it out, and you are good to go.

This tool is specifically designed to measure chamfer holes with wider angles. So, if your particular equipment has much smaller holes, it is better to go with the first few models on our list.
As we can expect from Starrett, this model is designed through AGD standards. The product also comes with a beautiful deluxe padded case.


  • No setting master required, easy calibration
  • Comes with a deluxe padded case
  • Designed to follow AGD
  • Durable


  • Quite expensive

Features to Look for Before Buying

A chamfer gauge is a very helpful tool in identifying the exact chamfer diameter or the edge that transitions one surface of a part to another. As long as you have a good chamfer gauge, you can get precise readings that will help you with your machinery.

However, not all chamfer gauges are created the same. Some may work for you, while others might not. Therefore, it is important to have an idea of what makes a good chamfer gauge. This will help you to end up with a good purchase and a good return on your investment.
Here are a few points you should consider in buying a chamfer gauge.


This is the most important consideration in buying a chamfer gauge, or any gauge and other measuring tools in general. You need a model that will give you precise, accurate measurements each time you use it.

You will notice that a lot of the models we picked on this review have an impressive accuracy of .001-inch, which is what you should get to ensure precise measurements.
Remember, each thousandth of an inch is crucial to any bushing, a pin, or screw.

Capacity and Angle

Capacity and Angle

Consider the equipment or tool where you need to use your chamfering gauge. Are the holes particularly large or small? Most chamfer gauges in the market have a capacity to measure 0 to up to 2 inches.

In terms of angle, it is highly recommended to use a chamfer gauge plunger that comes with an angle range greater than the hole you need to measure. This is because if the hole angle is greater than the chamfer gauge plunger’s angle, it might erroneously register a smaller diameter reading, making it unreliable.


Chamfer gauges, like any other dimensional measurement tools, do not come cheap. This is because only the top of the line materials and engineering is needed to produce one.
That said, it is better to spend a bit more in purchasing chamfer gauges where you are sure about the quality than settling for cheap ones that will fail.

Frequently Asked Questions

What is a chamfer gauge?

By definition, a chamfer gauge is a dimensional measurement tool made up of a plunger and a ratio indicator. It is used to measure the largest diameter of the holes along its top surface.

What’s the difference between chamfer gauge and countersink gauge?

Both are actually very similar in appearance. However, a chamfer gauge has a plunger with three fluted portions. On the other hand, a countersink gauge comes with a plunger of conical shape.

Are digital and electronic chamfer gauges available in the market right now?

For a lot of years, electronic or digital chamfer gauges had not been usable. This is because of the non-standard conversion ratios involved in chamfer gauging.

However, more and more digital indicators have been available in the market recently. Thanks to the special conversion ratios programmed to them!

In measuring the chamfer diameter, do I need to use a gauge which angle will match the hole’s angle?

Since the gauge plunger will only need to be in contact with the top edge of the hole, you don’t necessarily need the two angles to be the same.
Although, it is recommended that the angle of the plunger on a chamfer gauge is wider than the angle of the chamfer hole itself.

Are there some disadvantages in using chamfer gauge?

One disadvantage is that it requires you to count the revolutions on dial models in order to calculate a reading.

Final Words

With the best chamfer gauge, you will be able to get fast, accurate measurements that you need to check your machines or tool’s quality. Among the five models we reviewed, which one did you pick? Hurry and purchase it now and get ready to be amazed by how well they perform.
