Hamar Laser’s L-706SM Small-Bore Laser Alignment System is highly accurate and unparalleled for ease of use. It has been designed to work on very-small, bore-diameter applications to work with our 4×4 mm PSD targets. It is used primarily on short length, small diameter applications, such as heat exchangers, tube-sheet bore straightness measurements and large caliber gun barrel straightness. The L-706SM may be used at distances up to 15 ft (4.5 m).
If you do not see your application listed, please contact us to discuss your requirements. We will be more than happy to provide a solution that’s right for your unique alignment problem.

The L-706 Laser has been designed with a .750 in. (19 mm) mounting stud and flat face with magnets to hold it flush to fixturing. Since the laser beam is concentric to the OD to within .0005 in. (0.01 mm), a simple flat face and .750 in. (19 mm) hole on center is all that is needed to hold the laser (the extruder package includes a self-centering chuck fixture). The laser comes with a 2 mm laser-beam diameter to work with the T-220’s 4×4 mm PSD. Due to the small size the laser limited to about 15 feet (4.5 m) for most small-bore applications.
The L-706 system uses our patented self-centering target technology for the T-220 Target. Self-centering bore targets use no moving parts to self center in a bore and take just seconds to position the target in a bore for an accurate measurement down to .0005 in. (0.01 mm). This eliminates the annoying 0 and 180 measurements needed for typical bore targets.
The T-220 Self-Centering target can measure the alignment and straightness of bores from .75 to 2.0 in. (17.75 to 50.8 mm). The target comes with a 4-foot (1.2 m) pole for insertion deep into bores. Pole extensions are also available.
Hamar’s bore alignment systems are the most accurate in the industry. Our patented, self-centering targets combined with ultra precise lasers means accuracies down to .0003 in. (0.0075 mm) in 10 feet (1 m) are no problem for our line of bore alignment lasers.
The L-706 Laser has an angular adjustment range: ±0.06° (± .0125”/ft. or ± 1.04 mm/m) and is used on applications under 40 feet (12 m), such as extruder barrels and hinge-line bore alignments.
The R-1307B 2-Axis Readout has .0001 (0.001 mm) resolution with LED displays that can be seen from 10 feet (3 m). It features 9 hour battery life and the ability to change display resolution and system averaging. The R-1307B-2.4ZB version adds a 2.4 GHz radio to transmit the data to our Bore9 Software for recording and analysis.
Hamar Laser’s Bore9 software records alignment (concentricity) data for up to 50 bores. It also measures straightness of cylinders and can measure diameter changes when used with our self-centering targets in Measure Mode. It supports all of Hamar’s past and present bore alignment equipment and features a step-by-step guide to help the user through the software.
