Very clean finish on top as well as on the bottom - Among carpenters and joiners it has always been an art to ensure that the visible part of the work material shows the "clean side" of a jigsaw cut. Sometimes you have to turn the workpiece over to saw it, or saw from the underside to have the desired cut quality on the visible side. Or you can use the EXPERT 'Hardwood 2-side clean', which offers a perfect, tear-free cut on both sides thanks to its tooth geometry. The ingenious design of these jigsaw blades means that no further work is required after cutting. The teeth prevent tearing during the up and down stroke. This is perfect for professionals who want to save time and provide their customers with the highest quality work. Made from bi-metal - a strip of high-speed steel welded onto a flexible steel blade to combine strength and flexibility - the Bosch EXPERT 'Hardwood 2-side clean' jigsaw blade is tough enough to cut coated kitchen boards from coarse chipboard or hardwood. Available for tear-free straight cuts (T308BF) and for extra accurate tear-free angled cuts (T308BFP) Fits all T-shaft jigsaws.
