Logosol HSS - stays sharp at least three times longer
Logosol is now presenting a bandsaw blade with a five times longer service life. This bimetallic blade with HSS teeth has been developed by Hakansson Sawblades.
“They last significantly longer than normal hardpoint sawblades,” says Leif Håkansson.

Despite his surname, Leif has no connections with the sawblade manufacturer. He runs Flintarp Snickeri near Laholm on the Swedish west coast, and contacted Logosol in his hunt for a more durable sawblade.
He uses a large amount of dry oak in his production.
“Oak that has dried for 7-8 years is too hard for normal hardpoint bands,” says Leif, who was given the opportunity to try out the new HSS blade.
He purchases oak in blocks, and then breaks the blocks down with a large joinery bandsaw.
The new blades are available in various lengths and widths, both for log bandsaws and joinery bandsaws. Leif is satisfied with the results.
“The blades stay sharp for 4-5 times as long. They are a little more rigid, which means that they are not suitable for scroll saw woodworking, but they are even better for sawing in a straight line,” he says.
For people who wish to perform scroll saw woodworking, a narrower blade than normal is recommended. In a sawmill, however, the same width as in normal blades produces straighter sawing.
Tried and tested technology
Bimetallic blades have been used for metalworking for getting on for 40 years. In other words they are a tried and tested product, and one that is now available for sawing wood. Unlike sawblades with tungsten carbide tips soldered in place, the harder steel is integrated in the band. There is no risk of the teeth coming loose.
“The blades can also be resharpened around five times,” says Lennart Schwartz at the manufacturer Hakansson Sawblades.
A normal tungsten carbide tipped blade can be sharpened twice as many times, but as the HSS blade lasts five times as long, the results is a significantly improved service life. Even though the bands cost a little more, they represent a good deal for anyone who performs a large amount of sawing.
Soil and sand
“The new blades are of most benefit on a log bandsaw, although we also have HSS blades in dimensions suitable for joinery bandsaws,” says Lennart Schwartz.
HSS blades are more resistant to soil and sand in the bark, although they are not impossible to wear out. Sand and other contaminants are abrasive substances that, in time, would wear even a diamond blade.
“For people who saw hard wood types extensively, HSS blades are well worth trying out. You can saw for longer in between sharpening, and this reduces the cost per metre of sawing,” Lennart Schwartz sums up.
