Knight 4.5" Diamond Cutting Disc

This disc is designed for hard materials such as concrete, stone, brick, and metal, making it versatile for construction, demolition, and masonry tasks.

Key specs include a 4.5" diameter and compatibility with standard angle grinders. It’s designed to work with a range of materials and can be used with cutting fluids to aid cooling and maintenance during use.

To install: unplug the grinder, remove the guard if needed, place the disc on the appropriate shaft, secure with the correct flange and nut, and tighten firmly. Always ensure the grinding wheel is installed in the correct direction and that the tool’s guard is in place before use.

Always wear safety glasses or a face shield, gloves, and a dust mask or respirator. Use hearing protection if your work generates loud noise, and ensure proper ventilation when cutting dusty materials.

Use a steady, controlled feed without excessive pressure. Let the disc do the cutting and avoid forcing it. Allow cooling time between heavy cuts and use appropriate cutting fluids if required to aid cooling and longevity.

Common use cases include cutting concrete blocks, stone slabs, masonry bricks, tile removal, and metal cutting in construction or renovation projects where a reliable, durable disc is needed.

For similar tasks, you might consider the Knight 5-inch Diamond Cutting Disc (https://fepy.com/product/knight-5-inch-diamond-cutting-disc) for a slightly larger diameter, or the Knight 7-inch Diamond Cutting Disc (https://fepy.com/product/knight-7-inch-diamond-cutting-disc) for deeper cuts. If you need a segmented rim option, see Knight 4.5-inch Diamond Cutting Disc Segmented (https://fepy.com/product/knight-4-5-inch-diamond-cutting-disc-segmented). These options share the same diamond-infused durability and compatibility with standard angle grinders while offering different cutting capacities.

Store the disc in a dry place, inspect it before use for cracks or damage, avoid dropping it, and clean off dust after use. Use the disc within its intended material range and avoid overheating by using steady feeds and occasional cooling.

This disc is designed primarily for dry use on standard angle grinders, but you can use cutting fluids to aid cooling in demanding applications and to help manage heat buildup during cuts.

Replace the disc if you notice cracks, warping, significant wear, glazing, or if cutting performance drops noticeably. Continuing to use a damaged disc can be dangerous and lead to failure.
