Detailed Review
The FLEX CS 40 Wet Tile Saw is a dedicated cutting tool built for tile and masonry tasks. It provides high-speed cutting capability for tradespeople and DIYers who need to slice through tile materials with precision. Operating at a no-load speed of 12,000 rpm, it delivers rapid rotation for clean and efficient cuts.
The saw uses a 5-inch by 7/8-inch blade setup and includes a 20mm adapter ring to ensure proper fitting. For standard perpendicular work, it handles material thicknesses between 26mm and 41mm at 90 degrees. This provides enough clearance for standard to relatively thick tiles.
When angled edges are required, the saw features an integrated tilting range spanning from 0 to 45 degrees. However, the listing does not specify the maximum cutting depth when the saw is tilted to 45 degrees. It also does not list the overall tool weight, cord length, or water feed attachment details, so buyers looking for complete setup specs will need to verify those elsewhere.
Verdict: The FLEX CS 40 Wet Tile Saw is well-suited for anyone needing a high-speed saw capable of handling tile thicknesses up to 41mm at 90 degrees. It offers the essential tilting range and arbor compatibility needed for standard tile and masonry cutting jobs.
