Inwell IN0201115 4.5-Inch Segmented Diamond Saw Blades, 7mm Segments, 2-Pack

For cutting concrete, stone, or brick during a renovation, these Inwell segmented diamond blades pair a 4.5-inch cutting wheel with 7mm-high diamond segments. The segmented edge helps move debris away and improve airflow, while the two-blade pack keeps a second blade available for another job or a replacement.

Use them with a compatible handheld angle grinder or tile saw. The 7/8-inch arbor and included 20mm reducing rings support the specified fit, and the blades are designed for wet or dry cutting.

Key features

The diamond cutting edge is designed for hard materials including concrete, granite, stone, marble, masonry, and brick. That makes this set useful for tasks such as trimming masonry, shaping stone, or making cuts in tile and other hard surfaces. The 7mm-high segments and hardened steel body are built for demanding cutting applications.

The segmented design promotes airflow for heat dissipation and helps clear cutting debris. In practical use, that can make it easier to maintain a clear view of the cut line as you work. The manufacturer also describes the blades as low-vibration and low-noise. The maximum rated speed is 13,300 RPM, use a compatible tool and stay within its operating limits.

Customers often praise the blades for cutting concrete and stone cleanly at a reasonable pace. Feedback on durability is mixed: some buyers describe long-lasting use, while others report early blade issues. This set is a practical choice for shoppers seeking diamond blades for common masonry and stone-cutting jobs, rather than a blade intended for a different material or cutting task.

How to use it

Fit the blade to a compatible angle grinder or tile saw with a 7/8-inch arbor. The set includes 20mm reducing rings for the stated arbor fit. Choose wet or dry cutting to suit the job and the tool setup, and keep the tool’s rated speed within the blade’s 13,300 RPM maximum. A typical project might involve trimming a brick or cutting a stone piece to size, the segmented edge helps clear debris while you follow the cut.

Best use cases

These blades suit home renovation, masonry work, and other projects involving concrete, granite, marble, stone, brick, or block. They offer a focused alternative to choosing a general-purpose cutting wheel when the task calls for a diamond edge for hard materials. The 4.5-inch format is intended for compatible angle grinders and tile saws, so check the tool’s arbor fit and operating speed before mounting the blade.
