Our Top Pick is the Starrett Dial Caliper

Calipers are a valuable tool that many need to perform certain measuring tasks.  The Starrett Dial Caliper is easy to read thanks to the glare-free ruler that has a smooth satin finish and the white dial face.  Both of them are equipped with crisp lines that make reading the measurements easy.

The jaws of the caliper’s claws have knife edges that will carve parallel lines on wood or metal.

The depth rod is part of the caliper’s rack so it is very easy and convenient to use. The durable, stainless steel construction is long lasting and corrosion resistant which ensures that with the proper care, you’ll have these calipers for years to come.

Gear accuracy will never be a problem due to the positive double-pinion, anti-backlash control.  Users won’t have to worry about foreign substances clogging the gears because the teeth that is on the rack point downward rather than pointing upward or at a slant.

You will get precise, accurate measurements for depth, internal and external readings. There is a lock screw that will hold the sliding jaw in place and will lock the dial bezel as well.  There are many different professions that calipers are used in.  Most dial calipers are used for measuring size differences between two objects as well as measuring inside, outside, depth and step measurements.

They are one of three different types of calipers available and all of them work in very similar ways.  This Starrett Dial Caliper will be a great addition to your tool box and will give you the accuracy and reliability you are looking for.

The Starrett dial calipers use simple movements and backlash gears to get the precise measurements users need. If you have any reason to take them apart (which is not recommended) be careful because the parts can come loose and fall and you may lose something necessary to the proper workings of the caliper.  Remember where everything goes as you take them apart. Write it down if that helps. Sometimes trying to remember proves to be inaccurate.

The Starrett 1202 is a better made caliper than many of the standard version.  They are sturdy and have well made movement that is a big improvement over the old calipers.

Who Should Buy This

Dial calipers are one of three types of calipers that users have to choose from. Many prefer dial calipers due to the fact that they work well, are not super hard to use and there are no batteries or charging activities to worry about.

Whether you are in a profession that uses calipers on a daily basis, or you are simply working in your garage on projects that require you to take precise measurements of this type, the Starrett Dial Caliper is the way to go.

What Makes a Good Dial Caliper?

Dial calipers are a more user-friendly type of caliper that uses a dial that allows the user to add the number showing on the dial to the number on the main scale.  This gives the user the total measurement.  The Vernier style of caliper relies only on the points along the scale to get the measurements which can be a bit inaccurate.

Dial CaliperThe adjustable claw that a dial caliper uses, slides along the rules scale and will provide precise measurements of the internal and external diameters of an object along with the depth and step of that object as well.

Most of the dials on dial calipers are large which makes reading the measurements much easier than it can be on the vernier caliper.  The dial caliper will read in metric and inches. The outside diameter is measured with the large jaws of the caliper.

The inside dimensions are measured with the small jaws, depth is measured with the extending probe rod and the step measurements are taken by using the front of the dial caliper to provide the user with thorough measurements.

The Starrett Dial Calipers provide accuracy to plus or minus, one graduation per every 6”.  These capabilities are consistent as long as the surfaces being measured have not been bent, damaged or worn in any way.

Most dial calipers will be able to measure within a range of 0 to 6”.  There are also 8”, 12” and longer calipers available as well if you need them.  The longer calipers do tend to be much more awkward to handle than the 6” models.  If you are measuring something that is over 4” you will have an easier time if you get an 8” caliper.

The Step Up

Users can use these calipers for measuring internally, externally, depth and step as well for an all inclusive measurement that is precise and accurate.  The adjustable zero allows users to set zero at a distance that is convenient for the user.  The rod that measures depth is integrated into the rack.  The extra hard stainless steel jaws provide users with a caliper that will last a long time. Spare parts for the Brown and Sharpe are readily available should you need them.

You will have even more accuracy over the configurations of other standard gears because of the spring anti-backlash control.  For those who are not familiar with backlash, it is the amount of clearance available between the mated gear teeth that are in the controls.  This feature prevents the gear teeth from getting jammed.

Care Use & Maintenance

Taking care of your tools plays a part in how long they last and how well they continue to do their job.  There are several things you csn do to ensure that your dial calipers last a long time. There’s no reason why, with the right care and maintenance that your dial caliper can’t last for years and years. We have provided some valuable tips below for users to use as a guideline to keep their calipers in great shape for a long time to come.

When it comes to safety, calipers are not really dangerous tools to use or work with, so there is very little in the way of safety that is available.  Follow basic safety guidelines when it comes to working on the job site or with the tools you are working around and use good common sense.  The dial caliper should be kept out of reach of children, as they can break the internal jaws by playing with it. Tools are never toys, so even the ones that aren’t dangerous should be kept out of their reach.

Maintenance Tips

  • Check your calipers for accuracy using a gage block or gage block combinations
  • Wipe the beam of the caliper before each use to prevent getting dirt or chips into the rack teeth
  • If there are worn surfaces have them repaired
  • Do not oil dial calipers, this will only attract dirt particles
  • Use an air hose to blow dust and chips away – do this after every use, especially the teeth
  • Do not take the calipers apart unless you REALLY know what you are doing
  • Do not drop or hit the calipers
  • Do not get dirt in the calipers
  • Do not get the calipers wet or leave them in a high humidity area
  • Do not use any solvents in the dial movement, this will only gum things up
  • If you work in an area that rusting is a problem, lightly oil the exposed steel and then wipe it off with a cloth.
  • Remove any and all oil and water from the beam before measuring
  • When you first get the caliper, take a dry cloth and some wd40 and wipe off the exposed metal parts which are the beam and the jaws.  Do not oil the plastic parts.  Once oiled, take another dry cloth and wipe off all the wd40.
