Bosch GKS 18V-57-2 GX: rail ready saw in L-BOXX
Compatible with the Bosch FSN guide rail and FSN X crosscut rail, according to Bosch.
Check price on AmazonAffiliate link
A cordless circular saw is the quickest way to cut decking boards, joists, studs and sheets of ply or OSB without dragging a lead around. Blade size sets the depth of cut: 165 mm saws cut around 55 to 57 mm, enough for most decking and 47 mm timber, while 184 to 190 mm saws reach deeper for larger sections. Guide rail compatibility matters if you want clean, straight cuts in sheet material, and an electric brake stops the blade quickly after release. This guide compares 18 V saws by blade size, listed depth, rail compatibility and what is in the box, as many are bare units. Circular saws can kick back if the blade pinches: support both sides of the cut, set the depth just below the material, keep the guard working, and wear eye and ear protection as the manual and HSE guidance advise.
