Not all small openings need to be round. While many small holes are core or stitch drilled, the time saved with a square hole may reduce costs. A small opening can be made in as little as 5 minutes with ICS® concrete chain saws.
1. Score cut the opening on all 4 sides – 2 minutes.
2. Plunge cut each side starting at the center of each cut and working toward the corners – 3 minutes.
The result: A small opening, with perfect corners and no overcuts.
Total elapsed time: 5 minutes.
