The model J2 jaw gage features Dorsey’s proven precision lapped chrome/steel bushing in a rigid cast iron frame. A series of interchangeable contacts, and adjustable two axis rest stage along with a micrometer tail stock combine to make the J2 jaw gage suitable for most high accuracy OD inspection tasks.

LDAR gages feature a lightweight tubular steel frame with a reed pantograph movement. The pantograph movement utilizes parallel springs to transfer motion and is well suited to production applications as dust, dirt or coolant cannot harm or jam the mechanism.

This economical, heavy duty production gage features a rigid steel plate frame and our bullet proof reed spring gaging transfer. The LDAR mechanism is impervious to coolants, dirt, and contaminants and offers great repeatability.

Dorsey’s most popular series of ID/OD gage uses rigid steel tubing, cast end blocks, and a precision right angle transfer mechanism similar to our bore gages which gives accurate and sensitive readings.

Dorsey's Dynamike Model DYN groove gage combines a patented ball bushing slide with a series of gaging arms to suit almost any application. Gaging contact retraction is accomplished by using a conveniently mounted thumb lever while gaging range adjustment is accomplished by sliding the static gaging arm along its precision ground rail.

Bore gages are comparator type instruments used to compare parts being manufactured (unknown sizes) to known dimensions. “Setting” the bore gage to a known dimension requires the use of a reference master. The master ring is the most common type reference master used in industry and each ring is limited to one specific hole size. This means that a master ring inventory can reflect a large investment. Dorsey’s adjustable bore gage setmasters maintain all the advantages of master rings, but provide the added feature of adjustability. Within the specified capacity of each Dorsey “Setmaster”, any dimension can be set by easily adjusting the master to a preset combination of gage blocks.
