Hamar Laser’s L-706 Bore Laser Alignment System is highly accurate and unparalleled for ease of use. It can handle a wide range of bore alignment and straightness applications. Even extremely difficult bore alignment jobs, such as spherical bearings, can be done easily. The L-706 may be used at distances up to 100 feet, and is recommended for applications with higher pointing-accuracy requirements, such as engine block bore alignment. The L-705 is recommended for applications with lower pointing-accuracy requirements, such as extruder barrel alignments or aerospace hinge lines.

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.
Hamar Laser has developed the world’s first self-centering targets (A-510, A-512, T-220, T-221, T-1240) and bore adapters (A-510STA/A-510LTA, A-512STA/A-512LTA, A-514A/B/C, T-221STA) that use no moving parts to self center in a bore. It takes just seconds to position the target in the barrel for an accurate measurement down to .0005 in. (0.01 mm). This eliminates the annoying 0 and 180 measurements needed for typical bore targets.
We’ve been making bore alignment systems for 30 years and have the widest array of targets to check bore alignments with diameters from 1.2 in. (30 mm) to 40 in. (1 m). Most of our targets are self-centering and highly accurate with accuracy down to .0002 in. (0.005 mm) in 10 ft. (3 m).
For maximum mounting flexibility, the L-111 Laser Stand and L-102 Beam Translator are used to mount the L-706 either on a flat surface, L-106 Instruments Stand or on the flange of a bore. The powerful magnetic base can be reconfigured to mount the L-111 on vertical or horizontal surfaces. The L-102 Beam Translator uses a parallel-sided piece of glass to center the laser beam on the bore target without changing angle to within .0001 in. (0.0025 mm).
Our Bore9 Software records the bore alignment data, analyzes the results and produces a graph and report on the alignment. A easy-to-follow 5-Step procedure guides the user through the alignment with on-screen help text to aid in training. Bore9 runs on most Windows 7/8/10 laptops and tablets using our A-910-2.4ZB Wireless Radio Receiver to download the data from our R-1307B-2.4ZB Readout
The L-706 has 3x finer laser tilting capability than the L-705 for use in long-distance applications up to 110 feet (33 m). The laser beam can be adjusted to .001 in. in 100 feet (0.025 mm in 30 m). Due to the lower angular adjustment range, the L-706 does not work well with lower-accuracy bore applications, such as extruders or hinge-lines, where the L-705 is used instead.
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). In fact, the laser replaces the first reference target that a typical borescope would need.
