Product Description

The Starrett dial caliper has sharp black graduations every 0.100" on the no-glare, satin-finished stainless steel bar, and graduations on the dial every 0.001". One full revolution of the dial is equivalent to 0.100". These calipers have knife-edge contacts for measuring both inside dimensions (ID) and outside dimensions (OD). The knife-edge contacts can be used to scribe parallel lines on the workpiece. This caliper can be used with one hand through operating the fine adjustment roll with the thumb. The lock screw locks the dial bezel and holds the sliding jaw in position. The depth rod is integrated into the rack of the caliper, unlike many calipers which offer a detachable depth rod, or none at all.

The hardened stainless steel components, including the bar, measuring surfaces, rack, gears, and depth rod, offer corrosion resistance, increased accuracy, and long life. Positive split gear anti-backlash control offers increased accuracy over standard gear configurations. Backlash is the amount of clearance between mated gear teeth in the caliper controls, which prevents the gear teeth from jamming. It is undesirable to have much backlash due to the lack of precision offered by the increased amount of play between gears. Certain gear designs can minimize or eliminate backlash; split gear systems actually split the gear into two gears, each half as thick as the original gear. One of these gears is then fixed to the shaft while the other gear is allowed to turn. The free-turning gear is connected to coil springs that rotate it until all of the backlash in the control system has been eliminated. The rack teeth point down to keep foreign matter from clogging the gear operations. This prevents measurement errors where metal chips could interfere with proper caliper operation.

Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, and machining. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The digital caliper takes a differential by zeroing the display at any point along the slide, with an LCD that displays a single value in English and/or metric units.

Starrett 120A-6 Dial Caliper, Stainless Steel, White Face, 0-6" Range, +/-0.001" Accuracy, 0.001" Resolution Review

One of the reviewers referred to this caliper as being "heirloom quality". I feel that statement needs a bit of qualifying.Starrett has recently (within the past couple of years) made some changes to this caliper. I'll let you be the judge as to whether it was a good move. I should preface this by saying that I own several Starrett tools and have plans to add more to my chest (my wallet permitting).The first change that I'll speak to is with the dial housing. It has gone from being made from metal to plastic. I spoke w/a tech rep at Starrett who told me that It was a cost cutting measure as well as an attempt to make all the dials in their product line universal. He also said that he has fielded several customer complaints regarding this change. I have both versions of this caliper and the one with the plastic dial does not meet my expectations of "heirloom quality". It is a fine caliper but the plastic on this instrument detracts from the reputation for quality that Starrett has developed. However, the metal dial version of this tool, IMHO, embodies the qualities that Starrett is known for. I should also say that there is no functional difference, that I can find, between the two calipers. The other refinements (of the plastic dial version) are merely asthetic. The jaws have a slightly different profile and the depth rod is slightly thicker. Nothing that would provide anything better functionally. I hope that Starrett will return to producing calipers with a metal dial housing. If you can get your hands on one of these, then you will really have something that is "heirloom quality" Help other customers find the most helpful reviews� Was this review helpful to you?�Yes No Report abuse | PermalinkComment Comment
