mcp 32 Posted May 16, 2020 Share Posted May 16, 2020 Solid fibreglass is very very hard on jigsaw blades it seems. What type of blades have people had success with? Or do I just need to buy lots? Quote Link to post Share on other sites
Dtwo 157 Posted May 16, 2020 Share Posted May 16, 2020 Buy lots. Bimetal for thicker, wood for thin - but buy even more. Go as slow as you can. Quote Link to post Share on other sites

Got mine from Gail at Alltrades. Doesn't clog like the coated particle ones but go slow. Did all my window openings with them. We used the particle ones for cutting out fins from a 12mm solid laid up panel. Do you have any pictures of the blade you acquired and how long did each one last? I am cutting 12mm - 15mm solid polyester based fibreglass. Quote Link to post Share on other sites

From memory they lasted longest of any blade but weren’t suitable for tight radii. Used high tooth count TC skilsaw for the straight runs. Thicker kerf. The particle ones we used were TC as well. Diamond weren’t available then. How tight of a radius could you do? I need to cut two 190 mm round holes. Quote Link to post Share on other sites
eruptn 95 Posted May 20, 2020 Share Posted May 20, 2020 Used to cut a insert in bulkhead for GPS chart plotter, maybe 6-8 mm thick. Quote Link to post Share on other sites
