For pipe sizes DN ≥100 with wall thickness ≥ 10 mm, it is
recommended to deduct 10 mm from the above ”A” dimensions to
guarantee that the hole saw goes fully through the wall of the main
pipe.
The above ”A” dimensions are valid for Lenox holesaws. When
using a Sandvik hole saw, an additional 10 mm must be deducted
from these dimensions (A 38 mm diameter Sandvik hole saw is
10 mm lower than an equivalent Lenox one).
