plastics (Trespa®, PVC, nylon, polyester)
fiberglass and acrylic glass
soft tiles (surface hardness ≤6 Mohs), solid bricks and bricks with cavities, aerated concrete blocks, lightweight aggregate blocks and breeze blocks, soft density lime-sandstone building blocks (max 30 N/mm2 hardness); for hardness >30 N/mm2 use the diamond dry hole saws.
