HI, Can anyone, especially in the UK, point me towards somewhere I might get HSS slitting saw blades in 1" to 1.5" diameter and 7 to 10 thou thickness ( ideally 0.15mm) please? Thanks, Ian
Alouette Tool, a Swiss company might work better for you over there in the UK.
Thanks Pixman, I'll look for them...
